This the world's only f/0.95 35mm full frame lens. It works well for motion pictures, with superb bokeh and very smooth and precise direct mechanical manual focus perfect for use with a follow-focus rig. For astronomical, technical and scientific use it surprisingly has much better optical quality at f/0.95 than other Chinese f/0.95 lenses like the Mitakon 50mm f/0.95, but is far inferior to first-world f/0.95 lenses like the Nikon 58mm f/0.95 Noct that costs ten times as much. Optical quality improves as stopped down, but once you hit f/1.4 it's inferior to camera-brand 35mm lenses — for scientific, rather than artistic uses. Artistically, the image from this lens is sharp where it's in focus, and otherwise melts away quite nicely. It's a barrel lens with manual focus and totally manual diaphragm control, as if it came from a 1950s time capsule. It is manual-focus only and has absolutely no communication with your camera. You get no automatic lens corrections (which are responsible for much of the optical quality people take for granted today), no EXIF data, no aperture control and no autofocus. Image quality suffers because of this, and it makes it a pain to shoot. Even Auto White Balance can be fooled as cameras won't know the lens' set aperture, without which they can't know the absolute brightness and can't predict ambient conditions as intelligently as they do otherwise. Good news is that the manual focus system is excellent for getting precise and perfect focus when you're on a tripod and magnifying the image. I'd get my 35/0.95 at B&H for Canon RF, for Nikon Z and for Sony E, or eventually used at eBay if you know How to Win at eBay.
New intro topWorld's first and only f/0.95 35mm full-frame lens.
Good intro topSurprisingly good optics for such an inexpensive and exotic lens. All-metal construction. Unusually uniform 15-blade diaphragm ensures that blur circles are always round circles, not polygons and never lopsided. Great sunstars. All markings are engraved and filled with paint. Very precise direct mechanical manual focus for great results on a tripod. Defeatable aperture clicks. Hood included.
Bad intro topManual focus only. Primitive 1960s-style all-mechanical lens with zero electronic communication means no automatic corrections for lateral color, no corrections for distortion, no corrections for falloff, no camera-control of focus or aperture, reduced auto white-balance and exposure accuracy, no EXIF data, and possibly no in-camera stabilization if you don't enter "35mm" manually in the menus as the focal length. While this is the only 35mm f/0.95 lens in town, once you stop down to f/1.4 it has pretty poor optical performance compared to every other camera-brand lens. Highly non-linear aperture control ring; the smaller apertures are crammed so close together that f/11 is only a dot between f/8 and f/16. Mediocre coatings lead to slightly more flare than camera-brand lenses.
Missing intro topNo autofocus; manual focus only. No data communication; may as well be a 100-year old lens. No infinity focus stop; you have to focus at infinity manually (makes it tougher for astro shots). No automatic diaphragm control. No preset manual diaphragm ring. These were popular in the 1970s with lenses like this to make it easy to open the lens for focus and then close it down to the preset aperture to take the picture. No EXIF data. No ability to control anything about the lens (focus or aperture) from the camera.

I'd get my 35/0.95 at B&H for Canon RF, for Nikon Z and for Sony E, or eventually used at eBay if you know How to Win at eBay.
Overall performance topThis is an unusual new lens in a primitive, but well-made, all-metal mechanical mount. It has ZERO electronics.
Autofocus performance topThere is NO autofocus.
Manual Focus performance topManual focus is very smooth and precise. This is perfect for use on a tripod with magnified live-view at larger apertures to allow you to get perfect focus, but slow for general hand-holding at smaller apertures.
Focus Breathing performance topFocus breathing is the image changing size as focused in and out. It's important to cinematographers that the image not breathe because it looks funny if the image changes size as focus gets pulled back and forth between actors. If the lens does this, the image "breathes" by growing and contracting slightly as the dialog goes back and forth. The image from this lens grows as focused more closely.
Bokeh performance topBokeh, the feel, character or quality of out-of-focus areas as opposed to how far out of focus they are, is excellent at all apertures. This is one of the benefits of its less-than perfect optical correction. The 15-blade diaphragm always gives round blur circles, and it's far more uniform than automatic diaphragms so it's always round and not lopsided. Here are photos from headshot distance wide-open. I'm focused on the DAVIS logo. Click any for the © camera-original file: Made-in-U. S. A. Davis 6250 weather station, 13 August 2021. Canon EOS R5, 1/2,500 with Made-in-U. S. A.

Click any for the camera-original © files.
As always, if you want to throw the background as far out of focus as possible, shoot at f/0.95 and get as close as possible.
Coma performance topComa, or sagittal coma flare, is often seen with fast normal to wide lenses as weird batwing shapes on bright points of light in the corners at night. This is an artistic special-effect lens, and not one for all-out technical performance like the Nikon 58mm f/0.95 Noct, so yes, it has coma at f/0.95.
Distortion performance topThis lens has a little bit of pincushion distortion. I doubt it will be visible in any regular usage. See a sample at Lateral Color. For more critical scientific use, use a factor of -0.8 in Photoshop's lens correction filter. These aren't facts or specifications, they are the results of my research that requires hours of photography and calculations on the resulting data.
Ergonomics performance top
This is a very simple lens. The problem is that it's so simple that there is zero communication with your camera, which is required for easy usage. For instance, your finder will probably get too dark at small apertures as the camera gets fooled by the low light level and dims the finder because it thinks it's dark out because it has no idea that you stopped down the lens. Focus is very precise, which is great for careful tripod use but slow for general handheld photography. The focus ring is big and comfortable, more comfortable than the focus ring of Nikon's 58mm f/0.95 Noct! The aperture ring is thin and less easy to use, especially as only some parts are ribbed. Sadly there is no automatic diaphragm; you have to open and close it manually for every shot to focus and then expose unless you're shooting at f/0.95.
Exposure performance topYour camera's Matrix or Evaluative metering won't work as well with this lens because it doesn't let the camera know to what aperture it is set, so the camera has no idea what's going on and is much less able to predict optimum exposure for conditions. If you can't get good automatic exposures be sure to set A or Av mode. When set to P or S modes the metering system may get confused.
Eyeblow performance topThis has no eyeblow; no air pumps in or out of the back of the lens as focused.
Falloff performance topFalloff is moderately strong wide-open, and most cameras won't be able to offer any electronic help as there is obviously no lens data of profile for this lens. I've greatly exaggerated the falloff by shooting a gray field and placing these on a gray background; it will not look this bad in actual photos of real things:
Filters, use with performance topThere's no need for thin filters. I can use quite a stack of regular screw-in 72mm filters with no vignetting on full-frame. Go ahead and use your standard rotating polarizer and grad filters.
Flare & Ghosts performance topThis lens has inferior coatings to camera-brand lenses, so there can be more flare than other lenses. I never found it to be a problem. See examples at Sunstars.
Lateral Color Fringes performance topThere are relatively strong green-magenta lateral color fringes, and since there is no lens profile neither Sony nor Canon cameras will be able to do any sort of correction. Nikon cameras may do a good job of correcting this automatically; I haven't tried. Nikon does this without needing any lens profiles. There is also spherochromatism and other chromatic aberrations which can cause other kinds of color fringes on things that aren't in perfect focus. Door flanked by Robelinis, 9:57 AM, 13 August 2021.

Lens Corrections performance topThese is NO electronic communication with your camera, and there are NO lens profiles for this lens. Therefore there are NO automatic corrections available, however Nikons may correct for lateral color automatically. This limits this lens' performance; it would benefit from these corrections.
Macro Performance performance topThis isn't a macro lens. Its macro performance is awful; it doesn't get very close and it is poorly corrected at distances less then 3 feet (1 meter).
At f/0.95Technically it's loaded with all sorts of aberrations this close at f/0.95. I see plenty of spherochromatism and spherical aberration: Casio G-Shock Solar Atomic Watch at close-focus distance, 13 August 2021. Canon EOS R5, f/0.95 at 1/2,500 with Made-in-U. S.

At f/1.4It's much better at f/1.4 than at f/0.95, but still doesn't get close and the only optical prize it's going to win is the booby prize. Spherical aberration is better controlled, and there's still plenty of spherochromatism which causes the magenta flare on the trim on the front of the watch: Casio G-Shock Solar Atomic Watch at close-focus distance, 13 August 2021.

Sharpness performance topLens sharpness has nothing to do with picture sharpness; every lens made in the past 100 years is more than sharp enough to make super-sharp pictures if you know what you're doing. The only limitation to picture sharpness is your skill as a photographer. It's the least talented who spend the most time worrying about lens sharpness and blame crummy pictures on their equipment rather than themselves. Skilled photographers make great images with whatever camera is in their hands; I've made some of my best images of all time with an irreparably broken camera! Most pixels are thrown away before you see them, but camera makers don't want you to know that. People worry waaaaay too much about sharpness. It's not 1968 anymore when lenses often weren't that sharp and there could be significant differences among them; today they are all pretty much equally fantastic. This lens is sharper than I'd expect and contrasty at f/0.95 in the center at long distances, however the corners are soft at f/0.95 and have plenty of lateral color. The corners get sharper as stopped down, but the lateral color stays. It gets softer closer than about 3 feet (1 meter).
Spherochromatism performance topSpherochromatism, also called secondary spherical chromatic aberration or "color bokeh," is an advanced form of spherical and chromatic aberration in a different dimension than lateral chromatic aberration. It happens mostly in fast normal and tele lenses when spherical aberration at the ends of the color spectrum are corrected differently than in the middle of the spectrum. Spherochromatism can cause colored fringes on out-of-focus highlights, usually seen as green fringes on backgrounds and magenta fringes on foregrounds. Spherochromatism is common in fast lenses of moderate focal length when shooting contrasty items at full aperture. It goes away as stopped down. It has plenty of spherochromatism, however it has so many other aberrations at close distances it's hard to see it as a separate aberration at f/0.95:
At f/0.95At f/0.95 regular spherical aberration is strong enough to hide the spherochromatism at close distances: Mondaine A132.30348.11SBB at close-focus distance, 13 August 2021. bigger or camera-original © file.

Sunstars performance topWith a 15-bladed diaphragm, I can get great, sharp 15- to 30-pointed sunstars on brilliant points of light mostly at most apertures. This is much better than most "rounded diaphragm" lenses. Ignore the the vertical smear at large apertures, this is is a sensor artifact called interline transfer smear and not a lens defect. bigger or camera-original © file.

I'd get my 35/0.95 at B&H for Canon RF, for Nikon Z and for Sony E, or eventually used at eBay if you know How to Win at eBay. This is the world's only 35mm f/0.95 full-frame lens. If you absolutely, positively need f/0.95 at 35mm on full-frame, there is no competition. However, once you stop down to f/1.4, there are numerous much better lenses from Canon, Sony and Nikon. I still own, use and love my original Canon EF 35mm f/1.4L which I use on a Canon EF to RF adapter, which gives far better performance than this lens. This lens is very good by domestic Chinese standards, but if you value scientific sharpness then camera-brand lenses are in an entirely better class optically. If you use this for video or other artistic uses and you want a lens with a pleasant character, this lens has a very pleasant character. "Character" to optical designers means aberrations, flaws and defects. Character is the opposite of scientific optical excellence; if you want flawless optics for astronomy pass on this lens, and if you want character, check it out.
Recommendations topNew Good Bad Missing Compatibility I'd get my 35/0.95 at B&H for Canon RF, for Nikon Z and for Sony E, or eventually used at eBay if you know How to Win at eBay. This is an unusual lens. It's better for video than for stills as its optical quality isn't up to camera-brand lenses, however if you want artistic character and the ability to work great on a follow-focus rig — or need f/0.95 — this lens is better than I was expecting for its low price. I use a clear (UV) protective filter instead of a cap so I'm always ready to shoot instantly. I only use a cap when I throw this in a bag with other gear without padding — which is never. The UV filter never gets in the way, and never gets lost, either. The very best protective filter is the 72mm Hoya multicoated HD3 UV which uses hardened glass and repels dirt and fingerprints. For less money, the Canon 72mm UV and B+W MRC 010 are excellent filters, as is the B+W 72mm 010 and the basic multicoated Hoya filters, but the Hoya HD3 is the toughest and the best. Filters last a lifetime, so you may as well get the best. The Hoya HD3 stays cleaner than the others since it repels oil and dirt. All these filters are just as sharp and take the same pictures, the difference is how much abuse they'll take and stay clean and stay in one piece. Since filters last a lifetime or more, there's no reason not to buy the best as it will last you for the next 40 years. Filters aren't throwaways like digital cameras which we replace every few years, like it or not. I'm still using filters I bought back in the 1970s!
