7Artisans Launches a 50mm f/0.95 Lens for Multiple APS-C Mounts

Chinese camera lens manufacturer 7Artisans has announced the affordable $236 APS-C 50mm f/0.95 lens for Sony E, Nikon Z, Fujifilm X, EOS-M, and Micro Four Thirds (MFT) mounts.

The new 50mm lens joins what appears to be a consistently growing lineup of interesting and affordable manual lenses for mirrorless systems giving photographers and videographers even more choices for creative tools to add to their arsenals.

7Artisan's new 50mm lens will feature a "de-clicking" aperture with a range of f/0.95 to f/16. The design should make it useful especially for videographers. According to the technical specifications, the lens has a minimum focusing distance of 0.45 meters (17.7 inches), has a 31.8-degree field of view, a 62mm filter thread, and a 13-bladed aperture diaphragm. The lens is constructed of seven elements in five groups, and 7Artisans says that it features two HOYA ultra-low dispersion glass elements. The company says the lens body is made entirely of metal (including the lens cap) and weighs 416 grams. Additionally, 7Artisans claims that when attached to a mirrorless system, the lens and body are very equally balanced -- a challenging task given the sheer number of mount options that the lens is available for.

It is worth noting that the new manual-focus lens, like most of the 7Artisans line, does not come with vibration or shake reduction features. To keep the lenses budget-friendly, most of the lenses the company produces are pretty bare-boned: other than featuring fast apertures, the lenses are pretty devoid of other features. Additionally, while the "clickless" aperture ring is beneficial to videographers, still-photographers will have to double-check before shooting to ensure they have the appropriate setting for the shot they plan to take.

The Indonesian photography YouTube channel InfoFotografi already has a review of the lens available (with english subtitles) which gives the best look at the lens and its capabilities so far.

The 7Artisans lenses have proven to be some of the most affordable ways to get an incredibly "fast" glass that performs impressively well despite the low cost and in spite of the limitations that come with the all-manual design. To get an idea of how the lens performs, especially the quality of the out-of-focus areas (or bokeh), 7Artisans provided a set of sample images that can be seen below.

The 7Artisans APS-C 50mm f/0.95 manual lens will be officially available from the company's website and vendors starting on August 8th for approximately $236.

ZY Optics Launches its 50mm f/0.95 Speedmaster for L-Mount

Zhong Yi (ZY) Optics has announced that the mirrorless Mitakon Speedmaster 50mm f/0.95 lens originally launched for Sony E-mount, Canon RF-mount, and Nikon Z-mount (and later came to Leica M-mount) is now available for Leica L-mount. It is the first-ever f/0.95 lens that has been produced for L-mount.

The design of ZY Optics' 50mm f/0.95 was originally announced in 2019 and features 11 elements in eight groups and includes two extra-low dispersion elements to reduce color fringing and chromatic aberration as well as one ultra-high refraction element near the rear of the lens. The company included both an MTF chart and a diagram of the optical construction which can be seen below:

As noted in the original launch, ZY Optics says that the lens gives photographers "excellent control" over the depth of field and provides an "enchanting and dreamy" image thanks to its shallow depth of field. The bokeh is promised to be perfectly round thanks to the nine-bladed aperture. The lens also uses the common 67mm filter thread size.

The Mitakon Speedmaster 50mm f/0.95 has what the company describes as a "premium" build, with an all-metal housing that ZY Optics claims is highly durable.

"A solid feel of precision in hand is given by an evenly scaled aperture control ring and clear markings on the lenses’ bodies," the company writes.

That extremely fast aperture of f/0.95 is ideal for subject isolation, but also for low light photography.

"For any low light and night environment, our ultra-wide aperture is the best match for your shooting. Mitakon Speedmaster 50mm f/0.95 can reproduce light source consistently over the entire frame, without the presence of spiky coma flare," ZY Optics says. "The f/0.95 fast aperture also excels in night photography. Photographers can capture charming moments at night with ease with the Mitakon Speedmaster."

The company also touts the lens as ideal for videography, and says that filmmakers will find its de-clicked aperture allows for smooth transitions of exposure control. ZY Optics also says that its close-to-460-degree long focus throw allows a high level of precision in the adjustment of the focus point.

The Zhong Yi Optics Mitakon Speedmaster 50mm f/0.95 for L-mount is available now directly from the company's website for $800.

Laowa Argus 33mm f/0.95 CF APO Review: So. Much. Bokeh.

Venus Optics' Laowa lenses have been growing in both notoriety and popularity over the last few years thanks to their nearly constant stream of new and interesting optics for a wide variety of mounts. The company's latest is backed by the high-quality promise of its new Argus line: the Laowa Argus 33mm f/0.95 CF APO for APS-C systems.

The incredibly fast $500 50mm equivalent manual lens boasts an Apochromatic (APO) design -- which should prevent or correct any chromatic and spherical aberrations -- and is targeted at video shooters using APS-C systems. APS-C sensors generally means smaller optics, but the Argus bucks that trend and is by no means small. Weighing in at 590 grams (~20.8 ounces), you'll definitely notice it making your camera a tad front heavy when attached on pretty much all modern APS-C cameras.

As for using with it, since my own work focuses mostly on still images instead of video (and PetaPixel as a whole focuses on still photography first and foremost), this review will be mostly from the perspective of a still shooter.

Build Quality and Design

The 33mm Argus is a great feeling lens with a solid metal build and mount giving it a "high-end" feel. Even though this lens is meant for smaller APS-C systems, the lens looks and feels just like its bigger cinema counterparts. The lens itself is quite sturdy with a smooth "clickless" aperture and focus ring, a sleek blue ring at the end of the barrel, and is finished with a rectangular lens hood for a little cinematic flair. The focus ring has just enough tension to feel a little resistance when making adjustments, while the aperture ring is left feeling slightly looser by comparison. Overall though, it's wonderfully machined and feels great.

The only thing that threw me off on the aesthetic was the lens hood. Maybe my review sample is an outlier, but for some reason, it just does not sit symmetrically on the lens. That is to say, it sat just ever so slightly skewed to the right, and while this had absolutely zero impact on the shots I took, this tilt just kicked my OCD into overdrive and drove me crazy every time I had it mounted on the lens. It bothered me to such a degree that I just did not end up using it.

Focus and Aperture

Like many of the Laowa lenses in Venus Optics's lineup, the 33mm f/0.95 Argus is a manual focus lens only. After weeks of using and testing cameras that specifically tout the speed of their autofocus systems, using this manual lens was actually kind of refreshing. Enabling focus peaking is a must when shooting at such wide-open apertures as the f/0.95 offered here, but even then, simply breathing can make you miss the shot so, be prepared to fire a few extra frames in order to assure you've nailed that perfect focus.

A bit of a frustrating point with this lens is despite the large and smooth focusing ring, there is an excessive amount of throw in it.

I practically have to stop and take a break every time I'd adjust from near to far focusing. You effectively have to rotate the focus ring almost entirely around (270 degrees) to go from the close 0.35 meter to infinity focus. If this were in a cinema rig that takes advantage of a pulling unit, this wouldn't be an issue, but most shooters will definitely have to take two twists when quickly adjusting focus distance and likely you'll miss some key moments if you're shooting anything that's not sitting still.

The extra pull does have some usefulness when you're focusing up close as it allows you to really fine tune things, but if you're using it as more of a walkabout lens, get working on your forearm strength.

As I mentioned above, the aperture ring is clickless which is ideal for video and will work great if the lens is mounted in a focus pulling kit or gimbal, but as a photographer, it was incredibly easy to accidentally shift the f-stop without immediately noticing. There were countless times while using this lens that I would set it to f/0.95 and it would shift to f/1.4 or f/2.8 by accident and I wouldn't see it until I reviewed the shots. While I can see that having a clickless aperture is hugely useful in some cases, I think Laowa would have been better served giving us a click and de-click switch to make the lens more versatile like Sony does with its lenses. When in permanent de-clicked mode, it just feels like a cinema lens and not one that is tailored for photographers, which is a shame given the quality of images (more on that below).

Image Quality

How does this lens perform, especially considering the APO designation they claim? While we have not directly compared it yet to Mitakon or 7artisans rivals, from what I did shoot with the lens I found it to be surprisingly good, especially wide open in hard lighting situations. It was rather windy when I did some of the floral shots so nailing the focus was a challenge wide open, but the images were still pretty sharp and clean in the corners stepped up to f/2.8 but beyond that things got a little soft.

Does it perform the best here? No, but let's be real: people don't buy f/0.95 lenses for sharp images edge to edge at all apertures. They buy them for that super dreamy bokeh to draw attention to a subject that is very likely more centrally located in the frame. If it's decently sharp there, that's a win when the quality of the defocused area is nearly as important as what is in focus. While you can stop down with a lens like this, it's not why you get one.

And speaking of those defocused areas, the bokeh on this lens is the reason to get it: it's so dang nice. I did not notice any glaring rings or harsh spotting and only appreciated a soft, buttery goodness that the bokeh-addicts will absolutely love. I can see the Argus being used to create some incredibly dreamy portraits and even more interesting texture-driven and printable works of art.

The Apochromatic design of the lens supposedly ensures less color fringing and a much better color performance overall when compared to other fast lenses of similar focal length and aperture. This does not mean it will be sharper, only that you can expect better color accuracy in those extra shallow depth of field moments. Will there be vignetting when shooting wide open? Absolutely, but nothing unfamiliar and unexpected from a lens this shallow. The difference from the center to the corner edge is maybe about a stop of light when shooting closer objects and about two stops when shooting wide open for "landscape" images, but in both scenarios, the loss is easily recoverable in post.

Sample Images

Things I Liked

  1. Gorgeous bokeh
  2. Solid metal body and lens hood
  3. Smooth focus ring
  4. Sharper than I expected
  5. Chromatic abberation was minimal
  6. Great when set in a focus/aperture pulling kit for video
  7. Affordable price for a nifty fifty equivalent lens at f/0.95

Things I Didn't Like

  1. Heavier than I expected for an APS-C lens
  2. Clickless Aperture ring seems like a cool idea, but is frustrating in practice
  3. The amount of focus throw is almost obscene
  4. Crooked Lens hood drove me crazy
  5. Great for video, iffy for still work

Super Bokeh, But Is It Useful For Still Work?

The Laowa Argus 33mm f/0.95 CF APO is the company's first entry in its series of "high quality" lenses under the Argus branding. It seems like a fantastic lens for videographers and is definitely a good sign of things to come from the company. While there are a few things I did not enjoy about this lens -- the tilted lens hood, the amount of focus throw, and the "loose" aperture ring that would occasionally mess up my shots -- I still think it can be a fantastic addition to have in your APS-C kit. This opinion leans even more positive if you're a video shooter. For photographers specifically, its quirks can be annoying, but perhaps worth it for the bokeh it produces.

Are there Alternatives?

This lens is rather unique in its positioning with its only real rivals being similar lenses from Mitakon and 7artisans which have pretty good reputations for the most part. Venus Optics claims its control of aberrations is superior and has many samples to back that up, but it will be up to you to decide based on the images I show here and any samples the company has shared.

Should You Buy It?

Yes, for the most part. If you are a hybrid shooter that does both video and stills, then the Laowa Argus CF 33mm f/0.95 APO lens would definitely be a welcome addition to your kit for only $500. On the other hand, if you focus solely on stills, there are other options out there with autofocus that will treat you better for "in the moment" and action-based shooting situations. You'll just have to settle for f/1.4 or f/1.8 and miss out on some of that extra bokeh found here.
