TTArtisan 27mm F2.8 Auto Focus Lens for Fuji, Sony, Nikon

Item arrived very quickly and in good condition. The packaging is good. The lens itself is pretty nice. It's very compact, feels premium, and everything fits nice and tight. Maybe a bit too tight. The focus ring is smooth. The aperture ring is very nice to have but it's hard to grab sometimes when you can't reach the raised parts. The rear cap is bad. More on that later.

I haven't taken many photos with it yet. The auto-focus performance is poor at f2.8 but gets better when you stop down. Otherwise there's a LOT of breathing/hunting. The vinetting is very very heavy all the way to f7.1. Contrast is not great at f2.8 either.

Recommend buying an extra rear cap as the cap that comes with the lens is difficult to use and does not fit any other lens.
Don't forget to do firmware update. But after testing out the auto focus motor noise so you can compare! The difference is incredible!
Consider the 7Artisan 27mm f2.8 as well for a lens that's a bit bigger but should have a more usable f2.8.
