Laowa-65mm-f2.8-2X-Ultra-Macro-APO-lens-review

When I was offered the chance to review the Laowa 65mm f2.8 2X Ultra-Macro APO lens, I must admit I wondered what all the fuss was about. From a quick look, it appeared roughly the same size and price as the Fujifilm 60mm f2.4 R macro lens – but it is a manual focus lens.

Then I realized I had misread the specs – this is not a 1:2 macro like the Fujifilm XF 60mm f2.4 R lens, where objects appear half their size on the sensor. Nor is it a true 1:1 macro like the Fujifilm XF 80mm f2.8 R LM OIS WR lens, where objects appear their actual size. The Laowa Ultra Macro lens boasts 2:1 magnification. That’s right! It can take photos where objects appear up to twice their actual size.

In this gear review, I put the Laowa 65mm f2.8 2x Ultra Macro APO lens through its paces on my Fujifilm X-T2. If you’re not a Fujifilm shooter, keep reading anyway, Laowa has released lenses for many full-frame and APS-C mount systems.

Background

Venus Optics has made Laowa lenses in China since 2013. Most of the lenses they’ve created so far have been for full-frame cameras. Their line-up boasts an impressive range of lenses, including fisheye (fancy a 4mm f2.8 lens?), probe, ultra-wide, and ultra-macro lenses for a variety of camera systems.

The Laowa 65mm f2.8 2X macro APO is the first macro lens that Venus Optics has launched for non full-frame cameras. While this review is for the Fujifilm X-Series mount lens, it’s also available for two other mirrorless camera systems: the Sony E-mount and Canon M-mount.

Laowa specs

Let’s take a look at the specs for this lens, the Laowa 65mm f2.8 2x Ultra Macro APO.

  • The focal length is 65mm, which is approximately 97.5mm in a full-frame equivalent when you take into account the 1.5 crop factor of APS-C cameras.

A light blue soldier crab on the beach. It’s a wonder I managed to get a shot like this, these little guys move so fast, and they don’t like people! I had to prefocus before the crab came into view. Adults measure 25mm (1 inch). Fujifilm X-T2 with Laowa 65mm f2.8 2X Ultra-Macro APO lens.

  • 2x Ultra Macro refers to the magnification of this lens – it’s possible to take images where objects appear twice as large on the sensor as real life.
  • Typically, a macro lens is considered a true macro when it achieves 1:1 magnification. So with double that magnification, it seems the Laowa offering is worthy of the title “ultra macro.”
  • APO stands for apochromatic optical design. The lens has 14 elements in 10 groups, including three extra-low dispersion glasses to minimize chromatic aberrations across the frame.
  • Apertures range from f/2.8 to f/22, which you control via the aperture ring on the lens. It focusses from 17cm (2X life-size) to infinity.

The Laowa is slightly bigger in size and weight to Fujifilm’s 60mm macro lens, but is still very compact. It measures 57mm in diameter, 100 mm long, and weighs 335g. It takes 52mm filters.

What’s in the box

The lens comes attractively packaged in a sturdy box. Rather oddly, the lens seems to have two different names. On the website, it’s the Laowa 65mm f2.8 2X Ultra-Macro APO lens. On the packaging and on the lens itself, it’s the CF 65mm F2.8 CA-Dreamer Macro 2X.

Laowa-65mm-f2.8-2X-Ultra-Macro-APO-lens-review

The lens is attractively packaged and is all metal, apart from the plastic lens cap.

Removing the sleeve from the box, there’s an illustration of the lens on the lid. Inside the box, there’s plenty of foam to protect the lens, which comes wrapped up in a plastic bag with a drawstring.

Build quality

The build quality of the lens – especially at this price point – is excellent. Unlike many other lenses at this price point that are plastic, this lens is an all-metal construction. Even the lens hood is metal, with only the lens cap being plastic.

Using the lens

The Laowa 65mm f2.8 2X macro APO is a manual focus lens – there’s no communication between the lens and the camera body. You achieve focus by rotating the lens until the subject comes into focus.

Given that the lens has quite a wide range of magnification (from infinity to 2x life-size), sometimes it feels like you are twisting the barrel quite a lot to get your subject in focus at different distances.

Laowa-65mm-f2.8-2X-Ultra-Macro-APO-lens-review

Select your aperture on the lens and twist the barrel to achieve focus.

If you’re new to manual lenses, don’t be put off. A lot of macro photography work is done using manual focus, anyway.

At first, I did find it difficult to determine exactly what was in focus and what wasn’t, but this is more due to my eyesight more than anything else. As soon as I turned on focus peaking on my X-T2, things became much easier. I did find that at very close distances, focus peaking didn’t seem to work at all.

When using the lens, remember to check the barrel to see which aperture you’re using. As there’s no communication between the lens and the camera body, this won’t show up in your viewfinder display.

You may also want to keep notes on which apertures were used for your images, as these won’t record in the metadata either.

The lens has a nice click as you change aperture across the range. My only issue is that the settings for f/16 and f/22 do look a little alike at first glance due to the design of the indicators.

Depth of field at even the narrowest aperture of f/22 is very shallow when shooting up close. You may want to consider focus stacking to get a sharp image across the frame.

There are some stunning sample images on Laowa’s website, but I’d guess they achieved them with both focus stacking and possibly even extension tubes.

Image quality

I’m really impressed with the image quality of photos taken with this lens. As well as being sharp, they display good color and contrast.

I took the lens down to my local beach and took a lot of images of boats, items on the beach, as well as very fast-moving soldier crabs. I took the images of the boats handheld but shot the close-up images using a tripod and remote release. These two items are essential when working at such close distances, where shutter speeds may be slower than 1/60 second, and where any tiny movement may blur the shot or change focus.

Value for money

The lens sells for around $ 399 USD. This is very good value considering the image quality, and build quality, and the fact that you’re unable to achieve this magnification with any other lens available at present.

Conclusion

The Laowa 65mm f2.8 2X Ultra-Macro APO lens boasts some impressive specifications. The most impressive, of course, is its ability to produce images of objects that are up to twice their actual size.

Image quality is very good, I’m happy with the results the lens gave me on my Fujifilm X-T2. Photos were sharp and displayed good color and contrast.

The lens is light and compact, has an excellent build quality, and is competitively priced.

Although I’m not a specialist macro photographer, I really enjoyed using the lens. If you enjoy shooting macro images, I’d recommend giving it a go. It’s certainly a great lens for flora and fauna enthusiasts, keen to get up close to the action.

Tamron 20mm F2.8 Macro sample gallery

30 Jan

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_6112799146″,”galleryId”:”6112799146″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Tamron’s new trio of compact, 1:2 macro prime lenses includes a 35mm F2.8, a 24mm F2.8, and this lens, a 20mm F2.8 for Sony’s full-frame E-mount cameras. We found that the lack of a super-fast maximum aperture is at least partially made up by the impressive close-focusing distance, and the lens is weather-sealed and affordable to boot. Take a look at what this lens can do on a 61MP Sony a7R IV, and catch a glimpse of some Seattle snow while you’re at it.

The new Canon M-, Fuji X- and Sony E-mount versions of the 4mm F2.8 circular fisheye lens are currently available on Venus Optics’ website for $ 200.

Venus Optics adds Fuji X, Sony E & Canon M options to the Laowa 4mm f/2.8 Circular Fisheye Lens

Anhui China, Aug 7, 2019 – Venus Optics, the camera lenses manufacturer specializes in making unique camera lenses, add new Fuji X, Sony E and Canon M variants to the Laowa 4mm f/2.8 Circular Fisheye Lens.

Laowa 4mm f/2.8 Fisheye lens is an 8mm equivalent fisheye prime specially designed for mirrorless cameras with APS-C and MFT sensors. On the contrary to the Laowa ‘Zero-D’ wide angle lenses, the new 4mm fisheye lens is designed to create an extremely distorted circular fisheye perspective.

210° angle of view The lens features an ultra-wide 210° angle of view. Photographers can take advantage of the dramatic field of view to capture more than what your eyes can see. A full 360-degree panorama can also be done using just 2 images as opposed to shooting 6 or more images with conventional fisheye lenses. This lens is also particularly good for VR photography, shooting virtual tour, skateboard shooting and spherical panorama.

Fast f/2.8 aperture The ultra-fast f/2.8 aperture makes it an ideal option for astro-photography and shooting in lowlight condition.

Focus as close as 3.14” (8cm) from sensor Photographers can take advantage of the super close focusing distance to capture some heavily distorted & impactful shots.

Drones friendly The MFT version of the lens can be mounted on DJI Inspire X5 drones to create some epic ‘God’s vision’ shots.

Outstanding sharpness Houses with 7 elements in 6 groups, the new 4mm has an outstanding sharpness throughout the frame. Along with the 210o ultra-wide angle, photographers can either ‘de-fish’ the image in post-processing or crop to transform the image into a rectilinear image.

Super Tiny & Lightweight The lens is extremely tiny and lightweight. Measuring only 1.77” (45mm) long and weighing 4.7 oz (135g), the lens is so small that can be put into pocket for shooting anywhere, anytime.

Huge Depth of Field The depth of field of this lens is so deep that no focusing operation is required. Simply park the focus ring at infinity focus and stop down the lens to around f/5.6, everything will be in focus.

Pricing & Availability The lens is currently available to order from authorized resellers and in Venus Optics official website (http://www.venuslens.net/). It is ready to ship now. The ex-VAT retail price in US is USD 199/pc. Pricing may vary in different countries.

Lensrentals gets risky while tearing down the Nikon Z 24-70mm F2.8 zoom lens

18 Jan

Image credits: Photos published with kind permission from Lensrentals.


Over on ‘The Desk of a Humble Genius,’ Roger Cicala of Lensrentals has ‘finally’ taken apart the Nikon Z 24–70mm F2.8 lens and shared both his insights and images from the experience.

As the original title of the teardown, ‘Lens Disassembly is a Complicated Profession. Don’t You Agree?,’ alludes to, this particular disassembly proved to be a challenging one, which par for the course with Nikon lenses, according to Roger. In his own words, Roger says ‘Nikon lenses have always been a bit “old fashioned” and different from other SLR lenses,’ but this review comes with a very clear warning to ‘not get your lens and screwdriver and follow along at home,’ because ‘Bad things might happen. Bad. Things.’

The teardown starts off with what is about the only negative thing Roger has to say about the lens—the felt around the lens hood, which he feels peels up too easily isn’t up to the quality of the rest of the lens.

From there, it’s onto the mount, which was dissected one screw and ribbon cable at a time. Upon removing the mount itself, Roger noticed it was particularly difficult to get off. This was due to an inner lip that rests against the rear barrel of the lens. Roger says ‘This might be to keep the bayonet centered, for a dust seal, to provide a little extra strength, or just because it looks cool,’ but notes regardless of the exact reasoning, ‘it seems like an all-around good idea.’

Moving along, Roger removed the rear piece of the lens barrel to reveal the A/M focus switch and the optical sensor the control ring uses. Each piece removed reveals a healthy amount of weather sealing gaskets, as well as numerous electrostatic discharge (ESD) cushions under the exterior of the lens.

With the rear barrel off, Roger gets into the internals of the lens, which proved to be a pleasant surprise. In his own words:

‘OK, let’s take a moment for me to give some props. Forever, during Nikon tear-downs, I’ve made snarky comments about the old-fashioned look they have inside; soldered wires here and there, flexes wandering aimlessly, random secondary circuit boards, etc. Well, no more. Look at this engineering right here: neat flexes running directly where they’re heading placed in recessed channels in the barrel and thoroughly taped in place. Superb! Nikon has clearly modernized and spent time and effort in making a clean, well-engineered layout for the electronics. I’ve been asking for that for years, and Nikon delivered.’

The PCB itself also proved to be quite minimal, at least compared to the one found inside the Canon RF 70–200mm F2.8 lens Roger tore down a few weeks back. In the past, Nikon has used secondary circuit boards in the lenses to beef up the processing capabilities, but Roger notes there wasn’t another one inside this lens, suggesting the camera handles a generous amount of the processing power.

After a few other auxiliary bits, it was onto the removal of the next piece of the lens barrel. Unfortunately, this is where Roger and Aaron ‘ran into the “be careful what you wish for; you might get it” conundrum.’ It turns out one of those nicely-organized flex cables ran down to the display unit of the lens and refused to budge when attempting to lift the barrel.

A syringe full of rubbing alcohol isn’t something you usually want to see during a lens teardown.

‘Rule 63 of taking apart lenses is “thou shalt not tug a flex”; because tearing a flex is bad,’ says Roger in the teardown post. ‘[But] on Nikon lenses, because we can’t buy parts, tearing a flex is very bad.’ After countless attempts to use different means of removing the flex cable to avoid tugging, Roger and Aaron decided they were sick of holding off lunch and decided to use a little rubbing alcohol in a syringe to ease the adhesive from the back of the ribbon cable. After a little bit of pulling, the barrel was off and they were on their way.

Roger hits on a number of other interesting tidbits about the buttons on the lens and the unusually-bright neon-yellow tape strategically-placed throughout the lens. The zoom barrel proved to be weather-sealed incredibly well and the zoom position sensor Nikon uses is an upgrade from the traditional metal brushes it’s used in the past.

The remainder of the lens disassembly proved to be a doozy, with excellent build quality proving time and time again to be a double-edged sword for Roger, who seemed to be as challenged as he was impressed.

While we’ll leave the rest of the humor, photos and details to Roger in his full write-up, here are a few other notable details discovered throughout the remainder of the teardown process:

  • Breaking the front filter thread of the lens is going to be a very expensive fix, as the entire front barrel is a single piece, rather than a piece simply held on with a few screws.
  • Aaron had to put on gloves during the assembly, which in Roger’s own words means ‘shit’s getting real’
  • The aperture diaphragm assembly is a combination mechanical/electronic aperture with very tight tolerances

When all was said and done, this teardown proved to be the longest ever—and that’s before Aaron had to piece it all together. The good news is, it (mostly) took so long because Nikon went above and beyond when engineering this lens.

Roger says these new Nikon Z lenses are a far cry from their F-mount counterparts and much like Canon’s RF lenses, are likely completely new optical designs made in-house. He notes ‘The engineering itself is incredible in most ways [and] the neatly laid out and solidly adhered flexes reflect the careful design.’

Venus Optics releases Laowa 12mm F2.8 Zero-D Cine lens for PL, EF and E mount cameras

14 Jan

Venus Optics has announced pricing and availability of its Laowa 12mm T2.9 Zero-D Cine lens.

The lens, which Venus Optics claims is ‘the world’s widest T2.9 cinema lens covering Vista Vision/Full frame sensors,’ is a re-engineered version of its 12mm F2.8 Zero-D photo lens. It’s constructed of 16 elements in 10 groups, features two aspherical elements and has a minimum focusing distance of just 18cm (7in) from the sensor.

As the ‘Zero-D’ nomenclature in its name suggests, the Laowa 12mm T2.9 lens features ‘close-to-zero’ distortion. It offers up a 47mm image circle, which is large enough to support both full-frame sensors and the larger Vista Vision sensors found on RED Monstro and Arri Alexa LF cameras. It also works as a 17mm equivalent lens on Super35 sensors.

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_4661977635″,”galleryId”:”4661977635″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Both the aperture and focus rings use standard 0.8 mod gears for easy operability with follow focus systems. The focus ring has a 270-degree throw for smooth and precise adjustments. The lens, which is constructed of an aluminum alloy, measures in at 87mm (3.4in) long and weighs just 675g (1.5lbs).
