Ronkonkoma, NY – September 30, 2020 – The SIGMA 105mm F2.8 DG DN Macro | Art lens is the first prime macro lens designed by Sigma exclusively for full-frame mirrorless cameras, as the DG DN in the name indicates. Announced today by Sigma Corporation, this lens offers 1:1 magnification (life-sized) at a 5.5-inch working distance with internal focusing, and it is available in Sony E-Mount and L-Mount formats.

Exceptional focal plane sharpness with minimal aberration is achieved through a new optical formula featuring 17 elements in 12 groups with one SLD element. The lens design also features excellent peripheral brightness for pleasing bokeh, complemented by nine rounded aperture blades. The L-Mount version of the 105mm F2.8 DG DN Macro | Art lens is compatible with the SIGMA Teleconverter TC-1411 and TC-2011, increasing the maximum magnification to 1.4:1 and 2:1, respectively.

“In order to capture the minute details of small subjects, macro lenses must meet an extremely high standard of optical precision, and the new SIGMA 105mm F2.8 DG DN Macro | Art lens truly delivers,” says Mark Amir-Hamzeh, President of Sigma Corporation of America. “Whether you are shooting images of flowers, insects or just interesting objects around the house, the sharpness, bokeh quality and practical functionality of this lens will exceed the expectations of professionals and hobbyists alike.”

The Hypersonic Motor delivers smooth, quiet, confident autofocus in both close-up and portrait-distance settings, and the three-zone focus limiter switch allows for even swifter response when focusing exclusively in either the macro or more distant range.

The Sigma Art line has been consistently redefining both imaging excellence and satisfying handfeel, and this new lens continues that journey. The dust and splash-proof design, aluminum and TSC (Thermally Stable Composite) construction, a brass bayonet mount, plus well-damped switches and rings demonstrate the level of build quality that the Art name represents. The Aperture Ring can be clicked or de-clicked by flick of a switch, and the lens also includes an Aperture Ring Lock Switch function. Additional benefits include a programmable AFL button on the lens barrel, and compatibility with face and eye-detection autofocus.

The lens will begin shipping late October 2020. / MSRP: $ 799

My thoughts on the Micro Nikkor 60mm f/2.8G Lens and the 105mm Macro

28 Apr

The post My thoughts on the Micro Nikkor 60mm f/2.8G Lens and the 105mm Macro appeared first on Digital Photography School. It was authored by Lily Sawyer.

I must tell you first of all that before I had the Micro Nikkor 60mm f/2.8G lens, I have always used the bigger and heavier big brother – the Micro Nikkor 105mm f/2.8G Macro. While this article will be about what I think of the 60mm, I feel I must also compare it with the 105mm as I have used both.

dps-60mm-nikkor-micro-105mm-macro-review

Lens specs

Let’s start with the basic similarities: both are prime lenses with an f/2.8 maximum aperture and f/32 minimum aperture, have the same number of diaphragm blades and both rounded blades. Both are autofocus, and being G lenses, have an internal ultrasonic motor type.

In terms of differences, the 105mm has vibration reduction while the 60mm hasn’t. The 105mm weighs in at 720g, much heavier due to the size and optics with 14 elements compared to the 60mm at 425g with 12 elements. Interestingly, both have the same filter thread size at 62mm which I found handy when changing filters.

dps-60mm-nikkor-micro-105mm-macro-review

The main difference, however, for me (and the most crucial one of all) is the focusing distance, which is roughly 6 inches for the 60mm and double that for the 105mm at 12 inches. Why does this difference matter to me?

With the 60mm, I need to be really close to the subject to fill the frame. It can get quite tricky when being so close and sometimes I revert to manually focusing the lens. When photographing rings, to get a really great shot, you have to be extremely close for the ring to take up a lot of the frame. As I usually prop both the ring and lens on a steady surface, I can take my time to focus and get really close.

However, because it’s a wider lens than the 105, sometimes I just can’t fill the frame enough with very tiny objects. I then resort to cropping in post-production for these instances.

The 105mm lens with it’s narrower field of view means I don’t have to get as close to the subject and still can get close enough to fill the frame with it. I find there is less need for cropping in post-production too. Because I am usually photographing still life objects such as rings, movement isn’t an issue. However, this becomes one if you were photographing, say insects, where you can’t be close enough otherwise you disturb them and lose the insects as well as your shot.

When I use these lenses

dps-60mm-nikkor-micro-105mm-macro-review

Generally, and as a rule, when I’m doing smaller and shorter shoots like an engagement session, I bring three lenses – wide, medium and long. Because my shoots are mostly on location and often we walk around quite a lot, I try to pack as lightly as possible. For these types of shoots, I use my three prime lenses: a 35mm f/1.4 G, an 85mm f/1.8G, and a 105mm f/2.8 macro. The 105mm here acts as my longer lens and my macro without the bulk of the 70-200mm zoom and another micro lens being the 60mm.

When I do a wedding that only requires a few hours coverage, I also don’t bring my entire arsenal. Instead, I carefully choose my lenses to make sure I have everything covered for those hours. For short weddings, I pack my 24-70mm f/2.8 G, 70-200mm f/2.8G, 85mm f/1.8G, and 60mm f/2.8G. I don’t need the bulk of the 105mm when I cover that focal length with my zoom but I still need a macro, and the 60mm is perfect.

How I use these lenses

dps-60mm-nikkor-micro-105mm-macro-review

I find the Nikkor 60mm Micro Lens is such a versatile focal length and being a micro lens means I do not have to carry my 50mm f/1.4G along with my other lenses anymore. It fulfills both macro capability – mainly for the ring shot and close-up details like food, table setting, and flowers – and a versatile focal length that allows for natural portraits without distortion and those not-so-close-up details.

When using the 60mm for portraits, I am usually shooting with apertures between f/2.8 – f/5.6. When using it as a micro/macro, I am shooting at apertures between f/7.1 – f/11.

The 105mm, as well as being a macro lens, is also perfect for portraits and gives you that creamy bokeh with gorgeous background compression.

When using the 105mm for portraits (which I love doing), I am usually shooting with apertures between f/2.8 – f/4. When using it as a micro/macro, I am shooting at apertures between f/7.1 – f/8. I find that this lens really sings at f/7.1. I have set my camera to 1/3 stops hence the f/7.1.

Performance

dps-60mm-nikkor-micro-105mm-macro-review_

Both lenses have top specs and perform brilliantly. Generally speaking, I find that when shooting with both lenses, more ambient or available light is required.

Both lenses tend to produce more vignetting than other lenses. However, there is one main difference to the performance of both lenses. Provided there is enough light for the subject matter, the 60mm is faster and quicker to grab focus whereas the 105mm is slower and often hunts for focus. The 60mm works better for moving objects without flash than the 105mm in the same scenario. While the use of artificial light such as electronic flashes does away with this issue, I am mainly speaking about natural or ambient light.

Recommendation

dps-60mm-nikkor-micro-105mm-macro-review

In summary, I highly recommend both lenses both in quality and overall performance. I think there is a lens for each purpose. You just need to analyze which lens you require to achieve your aim. I don’t think there is a one lens for all. My preference is for prime lenses because of their cleanness and sharpness of images, and for me, they perform better.

However, they cannot compare with the zoom lenses when it comes to fast-moving and hectic shoots like weddings where I physically cannot be zooming in and out with my feet all day.

If you are looking for a prime that gives you the flexibility to shoot portraits and macro, then the 105mm is your lens. However, if you are after more of a travel, photojournalistic, natural view type of images and need a micro, then the 60mm would be my suggestion.

On family holidays, I used to carry my 50mm f/1.4 G. You can read here an article I have written on 5 creative uses of the 50mm. But that was during my pre-60mm days. Since then, my 60mm has replaced my 50mm for these occasions. If I am only allowed one lens for family holidays and travel, I go for the 60mm. I may have lost the wider aperture of the 50mm f/1.4 G, but as holidays are usually during the summer when light is abundant, the difference it makes is not an issue.

I hope you found this helpful. Do let me know your thoughts in the comments section below.

Sigma announces price and ship date of 105mm F1.4 ‘bokeh master’ Art lens

26 May

Sigma’s special ‘bokeh master’ 105mm F1.4 DG HSM Art lens made quite a splash when it was first announced back in February, and now Sigma is finally revealing when it will ship and how much it will cost. If you’re in the market for this behemoth of a lens—seriously, we got a hands on at CP+… it’s huge—for either Nikon, Canon, or Sigma mounts, you’ll have to pony up $ 1,600 USD and wait until “late June” to get it.

For Canon and Sigma shooters, this is a whole new speed of lens that you’ve never had access to before. For Nikon shooters, it’s an opportunity to save $ 600 on the Nikon 105mm F1.4E ED lens, which is currently going for $ 2,200.

To learn more about this lens, check out our hands-on coverage from CP+, read the full pricing and availability press release below, or visit the Sigma website.

Press Release

Sigma Announces Pricing and Availability for Its 105mm F1.4 DG HSM Art Lens

The “Bokeh Master” will begin shipping in Canon, Nikon and Sigma mounts in late June for a retail price of $ 1,599.00 USD

Ronkonkoma, NY – May 25, 2018 – Sigma Corporation of America, a leading still photo and cinema lens, camera, flash and accessory manufacturer, today announced that its 105mm F1.4 DG HSM Art lens will be available in Canon, Nikon and Sigma camera mounts in late June for $ 1,599.00 USD through authorized US dealers. The Sony E-mount availability will be announced later.

The “Bokeh Master” with Longest Focal Length Among Sigma Wide-Aperture F1.4 Art Lenses

The Sigma 105mm F1.4 DG HSM Art is the ninth lens in the Sigma F1.4 line-up designed for full-frame cameras. To combine outstanding wide-aperture, mid-telephoto performance with F1.4 brightness at maximum aperture, this lens incorporates 17 optical elements in 12 groups, including three FLD glass elements, two SLD glass elements and one aspherical lens element. This optical setup minimizes axial chromatic aberration to deliver ultra high resolution along with ample peripheral light volume, which minimizes vignetting. As a result, the area in focus is extremely sharp, while the out-of-focus area features a beautiful bokeh effect with highly natural colors, making this a desired lens for portrait photography. The optical design also minimizes sagittal coma flare, making it an excellent choice for capturing starry skies.

Meyer Optik is reviving Dr. Rudolph’s APO Plasmat 105mm F2.7 lens

21 Apr

Meyer Optik has announced its new APO-Makro-Plasmat 105 F2.7 lens, a modern version of one of the classic Plasmat lenses developed by Dr. Paul Rudolph 105 years ago. As with previous Meyer Optik revivals, the company is funding its product on Kickstarter, where it explains that the new Plasmat 105 “offers natural sharpness, unbelievable color reproduction, and a glowing bokeh united at every step of the aperture.”

The name Makro, Meyer Optik explains, was chosen by Rudolph in reference to the Makro-Plasmat’s suitability for 35mm, not macro, photography. The company says that while its revamped version of the lens offers performance that’s “in the spirit of the Plasmat lenses,” it created the model with modern camera gear in mind.

The APO-Makro-Plasmat 105 has a 105mm focal length, 60mm width, an F2.7 – F22 aperture, 1.1m / 3.6ft minimum focusing distance, manual focusing, 6 elements in 5 groups, as well as 15 steel aperture blades with an anti-reflex coating.

As with the original Plasmat lenses, Meyer Optik says its remake offers a unique combination of glow, bokeh, plasticity, and sharpness, explaining:

The lens is sharp but it takes away the razor cut, sterile, microscope like sharpness and replaces it by an even sharpness around the subject that flatters it and pleases the eye of the spectator. Thus the lens fills the whole space with amazing depth and at the same time with a smooth transition from focus to softness.

The company plans to offer APO-Makro-Plasmat 105 for 35mm cameras in the following mounts: Canon EF, Nikon F, Sony E, Fuji X, and Leica M. A model will also be released for medium-format mirrorless cameras in both Fuji GFX and Hasselblad X1D mounts.

The lens has already reached nearly three times its funding goal on Kickstarter, where backers who pledge at least $ 1,050 USD (offer expires in the next 17 hours) are promised an early bird lens with a serial number that matches where they fall on the backers’ list—the first person to pledge will receive serial number 001, the second person will receive 002, and so on. Once this first early bird offer is gone, backers will be able to get the lens for $ 1,100, $ 1,150, and eventually $ 1,300 when all early bird deals are gone.

Initial shipments to backers are expected to start in February 2019; shipping costs depend on region. To learn more or secure your own, head over to the Kickstarter campaign page.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’ & 70mm macro

01 Mar

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

Sigma’s new 105mm F1.4 DG HSM is a beast, weighing in at 1.6 kilos. We’re at the CP+ tradeshow in Yokohama, Japan, where we just got our hands on what Sigma is calling the ‘bokeh master’.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

Even without the hood, the new 105mm is a large lens, with a front filter diameter of 105mm. It’s not particularly long, but as you can see from this shot, which shows the lens mounted on a Canon EOS 6D, it has a very wide diameter of 116mm (4.6 inches). The large tripod ring is included, and can be removed for hand-held shooting.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

With the hood attached, the 105mm gets even larger.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

The new 105mm is unstabilized, which means that the only controls on the lens are an AF/MF switch and a very broad, wide-diameter focus ring. Manual focus is a luxurious experience on all of Sigma’s ‘Art’ series and this lens is no different. Judging purely from our brief experience on the show floor, autofocus speed is similar to the 85mm F1.4: smooth and positive without being as quick and snappy as lenses with fewer pieces of glass to move around.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

And there is a lot of glass inside the 105mm. The new lens comprises 17 elements in 12 groups, including three FLD glass elements, two SLD glass elements, and one aspherical element.

Sigma claims that the lens creates a beautiful bokeh effect, and the well-controlled sagittal coma should make it excellent for capturing ‘starry skies’. A 105mm wouldn’t be our first choice for astrophotography, but we can’t wait to get hold of a shootable sample, and see what it can do.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

Also unveiled at the show was a new macro lens, – a first for the Art range. The 70mm F2.8 DG Macro offers true 1:1 reproduction, and a dust and splash-proof construction.

The lens features an extending, floating, two-group focus mechanism. Optical construction incorporates two FLD glass elements, two SLD glass elements, and one element with ‘a high rate of anomalous partial dispersion and a high index of refraction’. This should minimize axial chromatic aberration. Sigma claims that two aspherical elements ensure ‘razor-sharp’ images at close focusing distances.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

The 70mm macro is a pretty compact short-tele lens when focused at infinity, but gets bigger when the included hood is attached. The front filter diameter is a modest 49mm. Three focus limits can be set, for reducing autofocus ‘hunting’ at short working distances.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

When the lens is racked to its minimum focus distance of 26cm (10.2 inches) the lens itself grows considerably in size (but the hood stays put). Focus is ‘focus by wire’.

At 515g (18 oz) it’s reasonably lightweight, and balances well on our A7R III (with an adapter). We got our hands on a Canon-mount version, but the 70mm F2.8 is also available in Sony FE mount natively.

Leading the way in F1.4 brightness
Since introducing its first SIGMA Global Vision F1.4 lens in 2012, the 35mm F1.4 DG HSM | Art, SIGMA has been adding wide-aperture F1.4 options to the lineup. Now, with the introduction of the new 105mm F1.4 DG HSM | Art, SIGMA offers a total of nine lenses with F1.4 brightness, including six for full-frame cameras and three for APS-C cameras. SIGMA has designed all of these lenses to offer minimal optical aberration and deliver incredible resolution and stunning contrast. Boasting the longest focal length of the F1.4 Art line lenses, the new lens combines outstanding resolution with a beautiful bokeh effect. Designed with great care to ensure that both the in-focus and out-of-focus areas of the photograph are equally satisfying to the eye, this lens is truly a “bokeh master.” The SIGMA 105mm F1.4 DG HSM | Art has earned its place as the flagship of the F1.4 Art line lenses, prioritizing image quality above all to fulfill the promise of the line, delivering truly amazing optical performance.

Key features

1. Optical system delivering unsurpassed F1.4 performance
In order to combine outstanding wide-aperture, mid-telephoto performance with F1.4 brightness at maximum aperture, this lens incorporates 17 optical elements in 12 groups—an uncommonly large number of elements for a prime lens. By including three FLD glass elements, two SLD glass elements, and one aspherical lens element, the optical system minimizes axial chromatic aberration to deliver extremely high resolution along with ample peripheral light volume. The area in focus is extremely sharp, while the area out of focus features a beautiful bokeh effect with highly natural colors, making this lens a powerful choice for portrait photography. The optical system also minimizes sagittal coma flare, making this lens excellent for capturing starry skies.

2. Exceptional peripheral brightness
The most effective method of ensuring ample light is to maximize the diameter of the first element of the optical system. With its large filter diameter of 105mm, the SIGMA 105mm F1.4 DG HSM | Art delivers a significantly greater volume of peripheral light than other lenses in its class. Minimizing vignetting while offering a beautiful bokeh effect, this lens is ideal for portrait photography.

3. Professional specifications
Like SIGMA’s Sports line lenses, the 105mm F1.4 DG HSM | Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection*, manual focus ring, cover connection, and other areas, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy. The high-speed, high-accuracy autofocus helps photographers react in an instant to get those special shots.
*SIGMA mount lens does not include sealing, since sealing is present on compatible SIGMA cameras.

4. Ease-of-use specifications
Instead of conventional ABS plastic, the exclusive lens hood features CFRP (carbon fiber reinforced plastic), a light but strong material used in the interior and exterior fittings of aircraft, among many other applications. The removable Arca-Swiss tripod socket is compatible with Arca-Swiss platforms and clamps, and its exclusive protective cover makes the lens easier to carry and use when shooting hand-held.

5. Compatible with full-frame Sony E-mount cameras The Sony E-mount version of this lens is compatible with Sony mirrorless cameras and contains the same optical system as the versions for other mounts. SIGMA MOUNT CONVERTER MC-11 is not required, as the lens performs the same functions as the converter, including in-camera image stabilization and in-camera lens aberration correction. In addition, the lens is compatible with Sony’s Continuous AF, which is not available via MOUNT CONVERTER MC-11. SIGMA plans eventually to offer Sony E-mount versions of every full-frame prime lens currently available in the Art line, from 14mm to 135mm.
Note: This product is developed, manufactured and sold based on the specifications of E-mount which was disclosed by Sony Corporation under the license agreement with Sony Corporation.

6. Compatible with Canon Lens Aberration Correction
The Canon mount version of this lens is compatible with the Canon Lens Aberration Correction function.* Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

DxO just published their review, and their analysis of the lens’ performance backs up what we saw in the field: it’s one of the sharpest lenses that Nikon currently produces. Check out their full review here.
