Sigma issues product advisory for its 60-600mm F4.5-6.3 and 70-200mm F2.8 Sports lenses

10 Jun

Sigma has issued a lens product advisory for its 60-600mm F4.5-6.3 DG OS HSM and 70-200mm F2.8 DG OS HSM lenses.

According to the advisory, posted below in its entirety, Sigma has ‘found a phenomenon whereby when pressing the shutter button on the camera body, it may occasionally stop operating and not respond to the reoperation.’

Due to this ‘phenomenon’ (someone’s been looking at Canon’s product advisories), Sigma says it will offer free lens firmware updates free of charge to customers with affected products within the following serial number ranges:

Sigma 60-600mm F4.5-6.3 DG OS HSM | Sports for Sigma, Canon EF and Nikon F Mount

Serial No.53824160 or earlier

Sigma 70-200mm F2.8 DG OS HSM | Sports for Sigma, Canon EF and Nikon F Mount

Serial No.53846990 or earlier

Sigma notes its USB Dock can’t be used for this firmware update ‘as it requires an adjustment to optimize each lens individually.’ So, if you’re noticing your lens having this issue and it falls within the serial numbers, Sigma requests you contact an authorized Sigma subsidiary/distributor who will then direct you to take the proper steps to get the issue fixed. You can find a full list on Sigma’s World Network webpage.

We spoke with a technician at Sigma America who said lenses that aren’t experiencing the issue don’t need to be sent in at the time and in the event a lens still under warranty does have the issue occur down the road, Sigma will still provide the firmware update free of charge.

Sigma has also noted that some products within the serial number ranges provided have already had their firmware updated. As shown in the above graphic, units with a black dot sticker above the barcode of the box have already been updated.

Lensrentals found a dead fly inside a Canon 70-200mm, tested how it affects image quality

12 Apr
A backlit photo of a dead fly trapped inside the inner elements of a Canon 70-200mm F2.8 lens, photos kindly provided by Lensrentals.

Thanks to ever-increasing reliance on firmware, the latest lenses can sometimes have bugs, but the bug Roger Cicala and his team at Lensrentals recently came across inside a 70-200mm F2.8L IS II lens wasn’t about to be fixed with the latest firmware update from Canon. That’s because it wasn’t a bug in the programming they encountered, it was a fly that managed to trap itself inside the optical elements of the lens.

Time for its close-up!

Somehow, a sneaky fly found its way into the deepest parts of a 70-200mm F2.8 lens, where it remained until its untimely demise. Naturally, Roger and his team wanted to remove the little critter, but not before they used it as an opportunity to see just how much a fly in the lens affected the performance of a lens and share the results (and process) with the world. In Roger’s own words, the blog post was written up for two reasons:

‘1) [To shot that] this big-ass fly had almost no effect on image quality, so that little dust speck you’re frantic about sure doesn’t, and 2) getting flies (or dust) out of a lens is a lengthy and difficult process that takes a long time.’

Just how well did the lens perform with the fly stuck inside of it? ‘Pretty well, actually,’ according to Roger. The Lensrentals team took the time to run a complete set of MTF tests and stopped down the lens across all focal lengths.

What the fly looked like stopped down to F13.

As noted in the blog post, there was no sign of the fly until the lens was stopped down to F13, but even then all that was visible was a shadow in the image. Stopped down to F22 and zoomed out to 70mm showed a much more prominent black spot, but even then it only took up a fraction of the frame.

What the fly looked like when stopped down to F22 at 70mm.

The remainder of the post details the teardown process and shows just how much effort goes into thoroughly cleaning out the inner-elements of a lens, especially a zoom lens as intricate as a 70-200mm IS lens. For all of the nitty-gritty details of the teardown process and more photos, head over to Lensrentals’ blog post.

Finally, the fly is discovered.

Roger’s takeaway message from the image tests with the fly-laden lens is ‘if your dust spec is smaller than a fly (about 4mm by 1.5mm) it’s not showing up in your images.’ He goes on to say in the ‘Final Thoughts’ section:

I think this does serve as a good demonstration of how little effect even a very large object inside the lens has. It would have a more dramatic effect, probably, if it had been located closer to the rear element. It’s also a really good demonstration on why we (nor anyone else who’s qualified) won’t clean the dust out of your lens for $ 50. Sure, a lot of lenses are easier to do than this one, but it’s still time-consuming and often technically difficult.

As for how the fly got into the lens, Roger deduces that it likely made its way into the lens through the small gap that’s made in the rear of the lens that can open up during the zooming process. The lens had been in Lensrentals’ rotation for 15 months, so he believes it found its way inside the lens after it left the factory. However, Roger admits he’s not a bug expert, so he’s not against hearing other possibilities.

Sigma 70-200mm F2.8 DG OS HSM Sport Review

07 Apr

The post Sigma 70-200mm F2.8 DG OS HSM Sport Review appeared first on Digital Photography School. It was authored by Anabel DFlux.

Sigma has made a significant name for itself via its famous ART line of lenses. But did you know Sigma also has a Sport line? Lesser known than the ART lenses, the Sport lenses are the incredible workhorses of the photography world (and deserve recognition). The Sigma 70-200mm F2.8 DG OS HSM Sport (Canon and Nikon Mount) is the newest addition to the Sport line, featuring a loved focal length. A big contender in the telephoto field, this lens may just be the top dog you didn’t see coming.

This lens focal length is so splendid, that the Digital Photography School even has an article on why you need a 70-200mm lens!

Lens build

Weight

I have tried many different 70-200mm F/2.8 lenses in the past, and currently own the newest one from Canon’s L line. This version of a favorite millimeter stands out. Before we even get into the construction, I can tell you that this lens is not the heaviest by far as compared to other brands like Tamron, and Rokinon, and older versions of the Canon and Nikon. As someone who tends to shoot sporting events for a good 12 hours at a time, my back is bowing in thanks at the decreased weight. Weighing in at a teeny bit less than 4 pounds, this is by far a more useable weight. The lens size is customary for this focal range at 3.7 inches in diameter by 8.0 inches in length.

Construction

The body is constructed out of a clever mixture of a very durable form of plastic, metal, and a new compound known as TSC (short for Thermally Stable Composite). The lens feels durable, and I found it to be more shock resistant than many of my other lenses. The glass itself is a high-grade glass mixture – 24 Elements in 22 Groups. I like the tactile feel of the focus and zoom rings, and it is very comfortable to use.

Weather sealing

This lens is built to work, and as such, its weather sealing is incredible. I feel very confident taking this lens out for a spin in whatever situation I find myself in. With the recent rains and odd weather in Southern California, I was still able to take this lens out in ease at a local outdoor sporting event. The weather sealing is a testament to a highly effective dust and splash proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.

That said, do use your best judgment to determine whether the weather is good enough to go out and shoot or not… weather sealing is not equivalent to weatherproof! As for the glass, the forefront and rear lenses incorporate water and oil-repellent coating that allows water to be wiped away easily. It prevents oil and fat from sticking to the surface, even in challenging shooting conditions, making lens maintenance easy.

The only downside I find with the lens construction is that you cannot remove the customary tripod foot (that many 70-200mm lenses have). This lens is also still technically heavier than the latest Canon or Nikon versions, but I’d argue this is a fair trade for how shock resistant and durable it is.

Lens features

As is customary for the Sigma lenses, the Sigma 70-200mm F2.8 DG OS HSM Sport features a slew of unique and useful features. Before we even get into them, it is worth mentioning that at this time, this lens is available only in Sigma, Canon, and Nikon mount. Sigma does offer a mount conversion service in case you want your lens to fit onto a different camera brand.

Sigma has gone the extra step to make sure that the mechanics of their lenses work as well as Canon and Nikon native lenses. The Canon mount version is compatible with Canon’s internal chromatic aberration control, and the Nikon version works with Nikon’s electromagnetic diaphragm.

Focus range limiter switch

A nice added feature for any telephoto lens is the focus range limiter switch, which restricts the range of distance your lens can focus. I use this feature myself when I photograph dog agility shows to make sure that the lens doesn’t focus on any obstacles near me but remains locked on a running dog that is far away.

Hyper Sonic AF Motor (HSM)

As the name suggests, this lens uses HSM (Hyper Sonic AF Motor) for its focusing. HSM uses ultrasonic vibrations to drive the focusing group. This motor benefits an internal focusing system.

You can easily override the HSM for manual control via a finger switch on the lens. A feature that goes along with this aspect is the Manual Override (MO). With MO, a photographer can continue using autofocus as usual, before making any final manual adjustments using the focusing ring around the lens. The lens can focus as close as 1.2m away from the subject unless restricted by the focus limiter.

The lens comes with a locking lens hood, which is superb considering the number of times the hood on my other lenses go flying off because they get bumped! The lock is sturdy, but still very easy to use when you need to get the hood off in a flash.

Focus

With a sport and action lens like this one, strong autofocus is the key to success. I photograph a slew of canine athletes, and you’d be surprised how incredibly fast those small champion papillons are! Additionally, to ensure the dogs are not distracted by the sound of my camera or lens, quiet autofocus is pretty high up on my list of needs too.

Lucky for me – and anyone else interested in this telephoto model – the Sigma 70-200mm F2.8 checks all of these boxes. The HSM motor keeps the autofocus noise to a minimum or nonexistent, which allows me to get a wee bit closer to the dogs as they make their impressive jumps and leaps.

The autofocus is rather accurate – even on small moving subjects like an Italian greyhound dog, through to bigger canines such as the border collie. The lens allowed me to capture the agility competition with ease. The focus was very smooth too, with little focus hunting, even when the clouds took over and the location became quite dim. No manic focusing movements either, like I’ve experienced with Tamron’s equivalent of this lens last year at a tradeshow.

In comparison to my Canon 70-200mm F/2.8 L IS USM III lens, this one performed just as good, and I would certainly consider it as an additional.

Sharpness

Although zoom lenses may never be quite the same level of sharpness as fixed focal lengths, this one still performs brilliantly despite this fact. Sharpness and contrast are excellent, even when shooting wide-open, throughout the entire zoom range. Centre sharpness at 70mm is excellent and just fine at all other focal lengths. Corner sharpness is high at 70mm, but at 100mm and beyond, corner sharpness takes a significant downturn at larger apertures. If you want to get the entire frame sharp, you’ll probably have to switch over to F/11 or so. That said, this isn’t unusual for zoom lenses. The contrast it produces is also excellent.

Depth of field

The F/2.8 wide aperture gives a nice subject separation and bokeh (the out of focus areas in an image). The depth of field is creamy and smooth, and very pleasing to the eye. The 11 diaphragm blades help to keep bokeh looking natural.

There is some vignetting on the edges. Some people like this, others don’t. I enjoy the natural vignetting that is contrary to popular opinion, but for those that find it a nuisance, keep this in mind.

Image Stabilization

The image stabilization system in this particular 70-200mm is superb. This lens incorporates Intelligent OS, which is the latest algorithm to deliver image stabilization. The intelligent OS works horizontally, vertically, or diagonally – whatever direction your lens is being held or used. The mode can be adjusted by a switch on the side of the lens and has two modes from which to choose.

The optical stabilizer was effective up to four stops – fantastic for a telephoto lens. The panning stabilizer was equally impressive, allowing me to track my subjects with ease while handheld. I took this lens out for a swing at a local concert as well. The F/2.8 aperture paired with stabilization, allowed me to expose my shots quite well.

Flare resistance & chromatic aberration

The glass coating on this lens does a fine job decreasing flaring and ghosting – an annoying issue that plagues photographers when the light hits the lens at a bad angle. The chromatic aberration control is quite good as well, with the optical array comprising of 24 elements spread across 22 groups. This includes nine FLD pieces of glass and a single SLD lens, all of which are used to help control chromatic aberration.

The Canon mount versions of this lens also benefit from compatibility with a full set of in-camera corrections for lens aberrations (a big yippee for me as a Canon user).

Pros and Cons of the Sigma 70-200mm f/2.8 DG Sport

Pros:

  • Durable, comfortable, solid lens build.
  • Superb weather sealing, as well as dust and moisture resistance.
  • Water and oil repellent coating on the glass.
  • The Canon mount version is compatible with Canon’s internal chromatic aberration control and the Nikon version is able to work with Nikon’s electromagnetic diaphragm.
  • Various switches built into the lens for professional use such as the focus limiter, modes, and image stabilization.
  • On the topic of image stabilization, the IS is superb.
  • HSM for quite and reliable autofocus.
  • The addition of an Manual Override mode for focus.
  • Locking lens hood.
  • Good flare and ghosting resistance.
  • Excellent chromatic aberration control.
  • Good center sharpness.
  • Very nice, creamy, natural bokeh.

Cons:

  • Tripod foot cannot be removed.
  • Vignetting on the edges.
  • Sharpness suffers in the corners at 100mm and more.
  • Weight

Conclusion

At a price tag of US$ 1,500, while this may seem hefty to some, it’s actually much more affordable than equivalent lenses of this caliber. There is a lot of bang for your buck. Moreover, it’s a very worthwhile investment for those shooting outdoors or in questionable conditions, as this lens is built to be the perfect workhorse.

I genuinely loved this model. It was very easy to use for my athletic needs!

We’ve been shooting a lot with Sigma’s redesigned 70-200mm F2.8 Sport lens and initial impressions are positive: it appears nice and sharp throughout the zoom range and proved quick to focus on the Canon 5DS R and EOS R. However at 1805g it’s certainly not a lightweight lens. Do the images make up for the awkward handling? Judge for yourself in our gallery of real-world samples.

Portrait Photographers: Do You Really Need a 70-200mm Lens?

26 Mar

The post Portrait Photographers: Do You Really Need a 70-200mm Lens? appeared first on Digital Photography School. It was authored by Simon Ringsmuth.

For many portrait photographers, the 70-200mm f/2.8 lens is considered the key to great results. This lens seems like it covers all the bases that any portrait photographer would want: wide aperture, a range of good focal lengths, and excellent build quality. It’s the cornerstone of many portrait photography workflows – and with good reason too – but it also comes with a hefty price tag (nikon, canon, sony). The question, then, for many amateur and semi-professional portrait photographers becomes: do you really need a lens like this to get good portraits? The answer might surprise you.

Nikon D7100, 50mm f/1.8 lens. Shot at f/2.4, 1/3000th second.

Whenever you are thinking about buying new gear, it’s wise to perform a needs assessment. This can help you figure out exactly what you can do with your current camera equipment, what you want to do, and whether a new purchase is required to bridge that gap. You can do this using a variety of methods, but a good way to start is to ask yourself some simple questions such as:

  • What camera lenses do I currently have?
  • What kind of portraits do I want to take?
  • Do I know how to use my lenses to get those portraits?
  • If not, can I learn to use my lenses differently instead of buying new gear?
  • In what ways are my current lenses limiting my portraits?
  • What lens would be best for the portraits I would like to be able to take?

Nikon D7100, 35mm f/1.8 lens. Shot at f/3.3, 1/90th second.

Perhaps your current lenses are lacking in specific areas such as the ability to shoot in lower light, overall sharpness, or autofocus speed. In that case, it might be a good idea to look at upgrading your gear. However, it is also entirely possible that the lenses you have are just fine for portraits and you don’t need new lenses at all.

If you do decide to drop some cash on a new lens, you might think that a 70-200mm f/2.8 lens is the be-all, end-all, ultimate goal to start saving for. Also, in many respects, you wouldn’t necessarily be wrong. However, you can get outstanding results with other lenses too and save a massive amount of money in the process. Here are some other lenses worth considering that produce excellent portraits for a lot less money.

Note: While I mostly mention Nikon and Canon lenses throughout this article, you can also get the same types of lenses for other systems like Sony, Olympus, Fuji, Panasonic, Pentax, and more.

The Power of the 50mm Prime

One of the most amazing lenses you can get for portraits is a humble 50mm f/1.8. The Nikon version is around $ 200 and the Canon retails for about $ 125, and there are plenty of third-party options available as well.

These little workhorses, sometimes called the Nifty Fifty or Fantastic Plastic due to the nature of their construction, can produce absolutely breathtaking results. In some ways, they are actually better than a two-thousand-dollar 70-200mm f/2.8 pro-grade lens. A 50mm f/1.8 lens has more light-gathering ability which means lower ISO values or faster shutter speeds in low light, as well as shallow depth of field.

Autofocus speed on these lenses isn’t going to win any awards, nor are they designed to take a beating or function in the rain and snow. However, they shoot great images in low light, and their wide apertures let you get the type of creamy bokeh you might have always wondered about but never been able to achieve with your kit lens.

Nikon D200, 50mm f/1.8 lens. Shot at f/1.8, 1/250th second.

If you’re the type of person who delights in pixel-peeping or poring over MTF charts, you might turn up your nose at an inexpensive 50mm f/1.8 lens. That’s not the point of a lens like this though, and what they lack in technical specs they more than make up for with sheer results. Also, at less than one-tenth the cost of a 70-200mm f/2.8 lens, their price-to-performance ratio is almost impossible to beat.

Nikon D7100, 50mm f/1.8 lens. Shot at f/4, 1/350 second.

The Mighty 85

One downside to shooting with a 50mm lens is that you won’t get much background compression. Your subjects won’t appear any closer to the background elements in the shot. While you can use an f/1.8 aperture to make the background blurry, it won’t zoom in much which is one advantage of a lens with a longer focal length. If that’s what you’re looking for, then an 85mm lens might fit the bill quite nicely.

Nikon D7100, 85mm f/1.8 lens. Shot at f/2.8, 1/350th second.

An 85mm f/1.8 lens is going to cost about two to three times what you would pay for a 50mm f/1.8 – around the $ 400 mark for both the Nikon and Canon.

In exchange, you’re going to get a hefty piece of equipment that is a little sharper, a little faster to focus, and will give you a bit more flexibility in terms of your portraiture. Its longer focal length will make it seem like backgrounds are just a bit closer to your subject.

In addition to their ability to get super blurry backgrounds when shooting at wide apertures, this could be the answer you are seeking.

Nikon D7100, 85mm f/1.8 lens. Shot at f/2.8, 1/750th second.

The 85mm focal length is ideal for many portraiture situations. I know professional photographers who choose to shoot with an 85mm lens instead of a 70-200 f/2.8 lens. 85mm lenses are smaller, lighter, and often just as capable as their big brothers.

Moreover, when you shoot at f/1.8, you can blur the background even more than a more expensive f/2.8 lens when shooting at similar focal lengths. While it’s true that the f/1.8 versions aren’t going to be as tack-sharp as their f/1.4 or f/1.2 counterparts, it’s hard to beat the value you get for your money.

Go wide with a 35

While many people tend to think of longer focal lengths as being best suited for portraits, you can get good results with a wider lens too. The 35mm focal length is close to what our human eyes see and can help you capture in-the-moment shots that are highly sought after by many people who want portraits. You can get up close and personal with a 35mm lens, shoot in low light conditions, and even achieve the buttery-smooth bokeh that you have always been craving.

Nikon D7100, 35mm f/1.8 lens. Shot at f/1.8, 1/1000th second.

Best of all, 35mm lenses are so cheap that you’re never going to break the bank with the Nikon coming in at around $ 200. Canon doesn’t offer a first-party 35mm lens but the excellent 40mm f/2.8 pancake lens is almost the same and even less expensive at about $ 175. My favorite part about a 35mm lens is that you can use it to get intimate images the likes of what a 70-200 f/2.8 could only dream of.

Nikon D750, 35mm f/1.8 lens. Shot at f/4, 1/90th second.

For years I shot almost exclusively with a 35mm lens on my full-frame camera. It was a constant companion of mine on everything from formal portraits to casual everyday shots. In fact, one of the biggest reasons I now use a Fuji X100F for almost all of my photos is because it’s basically the same as using a 35mm lens on a full-frame camera but in a much smaller package.

I wouldn’t go so far as to do entire portrait sessions with only a 35mm lens, but if you’re considering a way to upgrade your kit you might be surprised at how much mileage you can get out of this lens. I would even go so far as to say that you’d be wise to have it even if you do opt for a 70-200mm f/2.8, simply because it’s nice to have the flexibility of shooting at a wider angle when you really need it.

Nikon D7100, 35mm f/1.8 lens. Shot at f/4, 1/45th second with an external flash.

The main takeaway here, before I get to an examination of the 70-200mm f/2.8, is that you can do a lot with other lenses. Whether it’s one of these less-expensive primes or a more professional-grade lens like the Canon 85mm f/1.2 or the Nikon 105mm f/1.4 or any number of other lenses especially from third parties like Sigma and Tamron, the point is you don’t always need the heft and focal range of a 70-200mm f/2.8.

But sometimes you do.

70-200mm f/2.8: The Jack-of-all-trades

It’s impossible for me to say whether any individual photographer needs one of these lenses, but I can say that they are extremely useful in a variety of situations. They are professional-grade lenses designed to meet the demands of a variety of situations, especially for portrait photographers. If you really can’t get your work done with the gear you have, and if one of the other lenses I’ve already discussed isn’t going to meet your needs, then a 70-200mm f/2.8 might fit the bill quite nicely.

Nikon D750, 70-200 f/2.8 lens. Shot at 200mm, f/3.3, 1/250th second.

There are many times in which these lenses can outperform a lot of other options.

If you find yourself in situations like this, then a 70-200mm f/2.8 could be just what you’re after.

They are great for things like:

  • Fast-moving subjects who just won’t sit still. In other words…when you are photographing portraits of kids outdoors.
  • Full-body portraits where you want a nice blurry background
  • Subjects that are far away and you need to zoom in to see them
  • Group photos where you want to see the whole family but still have a nice blurry background
  • People moving towards the camera, either by themselves or as a group. You can stay in one place and adjust your focal length to zoom out while they get closer.
  • Action-style portraits of adults or kids while they are playing sports
  • Photographers who need a lot of versatility in their lenses, without wanting to change lenses or carry multiple camera bodies.

A 70-200mm f/2.8 lens isn’t always a necessity, but it can make a big difference if your needs aren’t met by other gear. They’re heavy and expensive, but the results can be worth it as long as you know why you want one and what you plan on using it for. You should also note that you might not need the sheer light-gathering capability of an f/2.8 aperture. In many cases, you would be well-served with a 70-200 f/4 lens which is going to cost significantly less and still produce good results.

Third-party options are a good choice too. You will often find 70-200mm f/2.8 lenses from Sigma, Tamron, and others available for about 50-75% of what you would pay for a first-party lens. These might not have the snappiest autofocus or same level of build quality, but for most portrait photographers they would work just fine.

Conclusion

Hopefully, this information, along with some of these pictures, helps you get a better sense of what different lenses can do. Of course, a 70-200mm f/2.8 lens is great, but if you examine your situation and think about your needs and goals, you might find that a different lens would suffice quite nicely. The point is to find something that works for you, no matter what it is and no matter what other people might use. As long as your gear helps you get the photos you want to take, then that’s all that matters.

Canon shows forthcoming RF lenses including radical 70-200mm F2.8 IS

15 Feb

Introduction

Alongside the EOS RP, Canon has announced the next six lenses it plans to introduce for its RF mount. Don’t be fooled by the timing: although they are being announced with the RP most of these lenses are not being targeted at entry-level or even mass-market customers.

Canon has already said it’s working on a full frame mirrorless camera aimed at professionals, and most of today’s development announcements make clear it intends to have appropriate lenses ready to suit it. All six lenses will be formally launched by the end of 2019, the company says.

Details are pretty scant right now (technically Canon is only announcing its intention to develop these lenses), but mockups of all six were on show at the pre-launch RP event.

RF 70-200mm F2.8L IS USM

To us the most exciting lens to be revealed is the RF 70-200mm F2.8L IS. Part of our excitement is that a 70-200mm F2.8 is one of the workhorses of any system. Pros and enthusiasts use these lenses for a whole range of shooting situations, from portraiture to sports, so it’s an essential ingredient for a system trying to appeal to high-end shooters.

Another piece of good news is that the lens uses Canon’s Nano USM lens motors. The company is a little cagey about exactly how these work, other than that they provide linear, rather than the rotational motion of the ring-type USM motors used in DSLR lenses. What we do know is that the fastest and smoothest focusing lens in the RF system so far (the 24-105mm F4L IS) is powered by Nano USM, which bodes well for the 70-200mm.

RF 70-200mm F2.8L IS compared to the EF 70-200mm

Oh, and the other interesting thing about the RF 70-200mm F2.8L IS? It’s TINY. Here we’ve shot it alongside the most recent EF 70-200mm F2.8L IS and you can see just how much smaller it’s going to be. Unless the ‘pro’ RF model ends up being huge, this is going to make an impressively compact combination.

Canon’s engineers wouldn’t be drawn on exactly how they’ve managed to make it so small, beyond pointing us back to the claimed benefits of the short and wide lens mount. There may well be something more complex going on: we’ll find out when it’s formally released but we were given the distinct impression that it’s not a diffractive optics (Fresnel) design.

RF 24-70mm F2.8 L IS USM

Another great pro workhorse is the 24-70mm F2.8 and Canon’s going to launch one of those, too. We’ve had no details about specifics but it’s a sensibly-sized lens, even if it isn’t as impressively small at its tele counterpart.

Canon has confirmed that it’s working on an in-body stabilization system

Like the 70-200mm the 24-70mm has built-in image stabilization and Canon has confirmed that it’s working on an in-body stabilization system for future camera models that will work in conjunction with this. So you’ll get stabilization on all RF bodies and even greater stabilization on others.

Like the 70-200mm, the 24-70mm will be driven by a Nano USM focus motor.

RF 15-35mm F2.8 L USM

The last in the cover-the-bases pro lineup is the 15-35mm F2.8. Canon says the RF lens mount allowed them to make it a 15-35mm, rather than starting at 16mm.

Again the lens is small and stabilized and, like the other two F2.8 zooms, will be driven by a fast, silent Nano USM motor.

We only wonder whether it needs more prominent markings to make it easier to distinguish from the 24-70, when they’re placed next to one another in a camera bag.

RF 85mm F1.2 L USM

While the trio of F2.8 lenses are all pretty compact, the same can’t be said of the 85mm F1.2. We thought the RF 50mm F1.2 was big (in part because we’ve only had the mid-range EOS R to mount it on, so far), but perhaps not unreasonably, the 85mm F1.2 is even bigger.

We’ve been impressed by the optical performance of the 50mm F1.2 so far. And, while we can’t be sure how much of that can be ascribed to the short, wide lens mount, Canon is clearly doing something right. A super-fast 85mm prime that can be confidently shot using off-center AF points is likely to be an exciting prospect as a portrait lens, even if you don’t always opt for for the hairbreadth depth-of-field that F1.2 can give you.

On the subject of focus, like the RF 50, the 85mm’s focus elements are too big and heavy for the use of a Nano USM motor, so it’s based around slightly less snappy ring-type USM drive.

RF 85mm F1.2 L USM DS

The ‘DS’ designation is new for Canon. Sadly it doesn’t mean we should expect avant garde engineering and styling. Instead, it stands for ‘Defocus Smoothing’ and promises improved bokeh, compared with the standard version.

If that makes you think of apodization elements (essentially an element that’s progressively darker towards the edge to prevent bright-edged bokeh), then the things we were told in our interview with senior engineers will only confirm that assumption.

The DS was the only lens not shown in mockup form as we’ve been told that not all the design decisions have been made yet. Despite this, a computer rendering of the lens has been issued: it says ‘Defocus Smoothing’ on the front, whereas the non-DS version does not.

RF 24-240mm F4-6.3 IS USM

The only lens not clearly aimed at a high-end audience is the RF 24-240mm F4-6.3 IS USM. It’s designed as a do-everything travel zoom, giving a 10x zoom capability.

We’ve mounted it here on the EOS RP and you can see it’s well matched (many of the other RF lenses have a wider diameter, and as a result lift the RP body off the ground if you haven’t attached the optional grip extension).

The two most obvious features are its comparatively small size and comparatively slow aperture range. We stress ‘comparatively’ when it comes to aperture, since you’d need a 15-150mm F2.5-4.0 on Canon APS-C to be equivalent, and few keen photographers would turn their noses up at such a lens. The other thing to notice is that it has only two rings, so we wonder whether the ‘focus’ ring will double as a custom ring when in AF mode.

Summary

The addition of these six lenses will extend the RF system to ten lenses by the end of 2019. With the three F2.8 zooms, 50 and 85mm F1.2s and the monstrous/rather cool 28-70mm F2, it means seven of the options have a distinctly high-end feel to them (and, we suspect, will have price tags to match).

This may leave EOS RP and many EOS R users a little short of choice (or push them towards adapting EF DSLR lenses), but makes very clear that Canon is gearing up for a pro-level RF camera sooner, rather than later.

Sigma announces pricing and availability of its 70-200mm F2.8 DG OS HSM Sport lens

11 Dec

More than two months after first showing it off at Photokina 2018, Sigma has announced its 70-200mm F2.8 DG OS HSM Sport lens will be available by the end of December 2018.

The lens, which rounds out the signature F2.8 trio alongside Sigma’s 14-24mm F2.8 and 24-70mm F2.8, will be available in Canon EF, Nikon F and Sigma SA mounts. It’s constructed of 22 elements including one Special Low Dispersion (SLD) element and nine F Low Dispersion (FLD) elements alongside an 11-blade aperture diaphragm and 1.2m (1.31yds) minimum focusing distance.

Following suit with most of Sigma’s other lenses in its Global Vision lineup, the 70-200mm F2.8 DG OS HSM Sport lens comes in at a discount compared to its Canon and Nikon counterparts. Sigma has set the retail price at $ 1,499 USD, a full $ 600 cheaper than Canon’s 70-200mm F2.8L IS III USM lens and exactly a thousand dollars cheaper than Nikon’s 70-200mm f/2.8E FL ED VR lens.

The 70-200mm F2.8 DG OS HSM Sport lens is available for pre-order on B&H (Canon EF, Nikon F, Sigma SA).

Sigma announces 28mm F1.4 Art, 40mm F1.4 Art, 70-200mm F2.8 Sport and 60-600mm F4.5-6.3 Sport

26 Sep

Sigma has announced four lenses for Canon EF, Nikon F and Sigma SA mounts. The 28mm F1.4 DG and 40mm F1.4 DG are both part of the company’s premium ‘Art’ range that prioritize image quality over price and weight. These two lenses will also be available for the Sony E mount. The new lenses help round-out the series, which now includes a range of prime lenses extending from the 14mm F1.8 DG HSM up to the 135mm F1.8 DG.

The 28mm F1.4 DG adds a semi-wide option to Sigma’s impressive range of ‘Art’ prime lenses.
The 28mm F1.4 DG | Art has a 77mm filter thread, matching that of the 24mm F1.4.
The 40mm F1.4 DG | Art is a near perfect ‘normal’ lens: a close match for the diagonal length of a full frame sensor. It’s been a historically popular focal length, so we’re pleased to see its return.
The Sigma 40mm F1.4 DG | Art has an 82mm filter thread.

In addition, Sigma has introduced a redesigned, stabilized 70-200mm F2.8. The 70-200mm F2.8 DG OIS is, as you’d expect, part of the company’s Sport range of optics and is likely to offer a less-expensive alternative to OEM 70-200s. We will, of course, be testing its performance as soon as one becomes available.

Finally, Sigma has announced the 60-600mm F4.5-6.3 DG OIS, a monster telephoto lens, also part of its Sport range. Despite the sport designation, we suspect the lens will be used more for birding and airshow shooting.

The Sigma 60-600mm F4.5-6.3 DG | Sport is a substantial beast, even at its 60mm setting.
But that’s nothing compared to seeing it at full stretch. It certainly lives up to the ‘Bigma’ nickname of its predecessor.

As you’d expect, it features a focus limiter, OIS control switch. In addition, there’s a ‘Custom mode switch’ that can be used in conjunction with the Sigma USB Dock to access customized adjustments of the lens’s focus and stabilizer behavior.

Sigma Unveils Five New Global Vision Lenses

Sigma’s 28mm F1.4 DG HSM Art, 40mm F1.4 DG HSM Art, 56mm F1.4 DC DN Contemporary, 70-200mm F2.8 DG OS HSM Sports, and 60-600mm F4.5-6.3 DG OS HSM Sports will make their public debut at Photokina 2018

LensRentals tears down Canon EF 70-200mm F2.8 Mark III and Mark II

01 Sep

LensRentals Canon EF 70-200mm F2.8 Mark III and Mark II teardown

When Canon announced the EF 70-200mm F2.8L IS III USM earlier this summer, the company was pretty open about the fact that it was a minor upgrade to its predecessor, featuring tweaked coatings and a new finish, but the same optical-mechanical formula.

Never ones to take a press release at face value (and since repairing lenses is a big part of their job) Roger Cicala and the team at LensRentals opened the lenses up to see whether Canon made any hidden changes. Not to spoil the surprise, but what they found… wasn’t a surprise.

All images courtesy of LensRentals, and used with permission.

LensRentals tears down Canon EF 70-200mm F2.8 Mark III and Mark II

The new Mark III version of the 70-200mm F2.8 is indeed optically and mechanically identical to the older Mark II. In Roger’s words: “If you think there’s an optical or performance difference, please contact me about some Tennessee Beach-front property I have for sale.”

But that doesn’t mean that they’re not optically and mechanically interesting lenses. According to Roger, the various versions of the Canon EF 70-200mm F2.8 are possibly the most popular lenses that the company has in their loan stock, but because they’re so complex, internally “the 70-200mm f/2.8 is […] one of the ugliest bits of engineering in the Canon fleet”

If the containing tape in the last photograph didn’t give it away, the camera-side internals of the 70-200mm F2.8 II/III are something of a rats nest of fragile ribbon connectors, wires and PCBs. “Not much fun to work with” says Roger, and we believe him.

This shot shows the rear group (being lifted off) connected by one remaining ribbon to the image stabilization unit. The rear group acts as a single centering element, making it “a bit of a pain to adjust”, requiring repeated adjustment, reassembly, more adjustment, reassembly (again) and so on, until it’s correctly aligned.

Here’s the IS unit, removed from the main lens barrel. The tweezers indicate one of the four posts that stop the IS unit from moving around too much inside the lens. To avoid damage to the IS unit during travel or shipping, Roger recommends turning IS off when the lens is still on the camera. Otherwise the element won’t lock and these plastic posts are the only things stopping the lens from banging around freely inside the barrel.

Two layers of weather-sealing tape (which the LensRentals team tells us is pretty much the same material as this stuff) protects the 70-200mm’s front group, and helps prevent water ingress. This is how the LensRentals team gets access to the front element of the 70-200mm, which they have to do a lot, to replace scratched front elements, get rid of dust and make optical adjustments.

So is the new Mark III version worth upgrading to? We’re not convinced, and neither are Roger and his team. Both are excellent lenses, and if you can find a Mark II for a good price, go for it.
