[7] For such an inexpensive lens, I keep expectations moderate, but this lens performs extremely well! Sharpness is better than expected, as well as the autofocus. Only issue is the noticeable vignette, but I really only notice it on shots with the sky. Otherwise, it does not bother me. It stays on my camera most of the time now!

[56°] so happy with this lens. it performs like a much more expensive lens. it feels solid and all the connections and moving parts are well engineered. very happy with the wide angles i can capture and how clear they come out. it is all manual and you will have to play with it a bit to get the focus just so, but once you find the sweet spot, it is remarkably sharp. highly recommended lens.

[f/16] Excellent substitute to the Fuji version. Fast quiet af.

[APS-C] Excellent lens and exceptional value if you can't afford the Fuji brand. Works great and looks beautiful on my XT-3. Perfect match and perfect pictures

[Autofocus] If you are on the fence about this lense for the Fuji, I suggest you go ahead and take the leap. A great priced and affordable alternative to the more expensive Fuji of compaerable specs. I find the AF is fast enough, it opens wde enough for lovely photos even at dusk. (Evening may be a bit of a stretch depending on light sources avail). The best part is it truly makes my camera a walk around Camera. I came from x100 so i was used to a smaller profile and was concerned when I got the xt1. But coupled with this, its totally fine.
TTartisans make decent lenses, I have several manual ones for my other cameras so when I heard they had one with AF and it was a virtual pancake, it was a no brainer. I also Love the manual control over aperture, it clicks and moves quite smoothly and helps make the transition from x100 smoother for me. Overall I recommend it for those on a budget or who want a light weight alternative.

[7] Picked up this lens for some fun street photography shots. Unreal craftsmanship at a stupid low price. Win/win for fun wide shots.

[Nikon Z] This lens is fantastic on both my Fuji X-E1 and X-T20. For the price, it's definitely a winner!

[39 mm (Front)] This is my second time trying this lens, and I should have kept the first one. It has noticeable vignetting, but the sharpness more than makes up for it! This lens is way sharper than it should be for the price. The sharpness exceeds all of my expectations at all apertures. The vignetting is quite noticeable at f/2.8 - f/5.6 (or higher) but if you can get past that, you’ll be pleased with the images. The autofocus is quick and snappy, and it is super compact. Highly recommend, and be sure to give it a chance before discounting this lens!

[f/2.8] Small compact lens. Rumors of it not being sharp wide open are false. My lens is sharp at 2.8, aperture ring kinda tight, but not in a bad way.

[APS-C] I received this lens about 2 months after getting the Fuji 27mm f/2.8 R WR lens. Both lens are sharp, although there were a couple of noticeable differences in the two lenses:
1) The TTArtisan lens appeared to be slightly wider (shorter focal length) than the Fuji lens.
2) Both lenses are not completely silent. Whereas the Fuji lens is known for having AF noise, the TTArtisan lens has aperture noise. If you set the aperture to f/2.8 and there is low light, the aperture stays at f/2.8. Otherwise the lens makes some noise as the aperture adjusts to the scene. Note that this aperture noise, on my sample, was more quiet than the Fuji AF noise.
Overall both lenses are excellent, although not silent, and both are small and light. The one plus to the Fuji lens is the weather seal, although at a much higher price point. You will be happy with either lens!
