7artisans lenses often is budget friendly and cheap lenses. You need to try this brand. This
7Artisans 50mm F0.95, as a well-built and compact, is made for APS-C mirrorless camera, and it consists of seven elements in five groups, along with two ultra-low dispersion elements. Also, this lens is available for Sony e, Nikon z, Fuji x, Micro four thirds and canon EOS M.
Firstly, let’s talk about its design. It is very compact and well-crafted lens and it is small yet a little heavy because of its 67.5mm length and 416 grams weight. Its filter diameter is 62mm.
If you mount the lens on APS-C cameras, it is a good balance. It has a ring aperture, which can allow users to adjust the aperture from f0.95 to f16. For some video shooters, this is a great lens because it is click-less and smooth and make no noise when do focusing. one of its bullet points is ring aperture, allowing users to transmit from infinity to minimum distance.
Let’s talk about image quality. I attached this lens on Sony A7, there is a little vignette and at the edge of the photo frame, it is black as this lens is not big enough to cover the full frame sensor. If you use Sony Alpha 7R IV(61mp), you can get 24mp. At f0.95, images are dreamy. In focus area, images are less sharpness and contrast. In out of focus, images are pretty smoothness and blur in the background. This lens is suitable for portrait photos and wedding event if you are lighting the condition. When stopping down to f/1.8 or f/2, you will get sharper images. At f/4 and f/8, you also get some much sharp photos as well.
At f/0.95, there is some chromatic aberration. For its edge, there are some purple and magenta and great tints happening here. But don’t worry. The CA only appears in some contrast backlight condition. At f/4 and f/8, the CA is not noticeable. If you want some flare in your images, f/0.95 will offer that effect.
Overall, I think it performs well a little bit challenging wide open at times and the images need some extra processing to get the most out of them but certainly solid all-round performer. If you want to shoot some videos, it is a great lens for delivering that elusive cinematic look but you must bear in mind that this shallow depth of field will put your manual focusing skills to the test.

I bought this lens just a few days ago. It is substantial and the bokeh is very nice, but there is a major problem with it: It isn’t actually an f/0.95 lens.
The first time I used it, I was surprised when I noticed that the meter on my Nikon Z30 didn’t show any increase in light coming through the lens as I opened the aperture beyond f/1.4. Mystified, I took a closer look at the aperture through the lens and noticed that around f/1.3 or so, as I turned the aperture ring towards f/0.95, the iris exposes a fixed metal aperture directly behind it that effectively keeps the aperture from getting any faster even though the iris continues to open.
To verify this, I checked the lens against two Nikon 50mm f/1.8 lenses I own, which I mounted on my Z30 using a Nikon FTZ II adapter. One was an AF-D and the other was an AF-S lens. Aiming at the exact same scene (a wall in my house) at that distance in the same light using the same ISO with all three lenses, I got three very similar histograms. I took the photos at f/2 with the Nikon lenses and with the aperture set at f/0.95 with the 7Artisans lens.
The results verified what I had observed. f/0.95 should be 2.1 stops faster than f/2. The AF-D lens shot the scene at f/2 @ 1/50 second. The AF-S lens shot it at f/2 @ 1/40, producing a slightly brighter histogram. At f/2 the two lenses were about 1/4 stop apart from each other. Given this result, at f/0.95, the 7Artisans lens should have used a shutter speed around 1/200. In fact, the shutter speed from the 7Artisans lens was 1/100, producing almost exactly the same histogram as the AF-D lens. This meant that the 7Artisans lens at its maximum aperture was effectively only one stop faster than the AF-D lens, which would be about f/1.4.
To be perfectly frank, I feel cheated by this. I already own a f/1.2 Canon rangefinder lens that I can mount with an adapter. I also already own an Nikon f-mount f/1.4 lens. My main reason for buying the 7Artisans lens was to get that extra stop and the extra bokeh that comes with it.
