Nice and wide, compact yet durable lens. The focus ring is nice and difficult to turn, and the aperture ring clicks at every half-stop (not great for video, but perfect for stills). I got some great astro shots after finally figuring out what I was doing. Manual focus only and no lens metadata links. While I'm happy with it for my purpose, looking back I don't think I'll get it again. Around the same time I got an Olympus 12-40 PRO, which at f2.8 wide open versus f/2 wouldn't make much of a difference. If I could do it again I'd shell out a few hundred more and go for the Laowa 7.5mm f/2 instead to get a really wide angle and get something more differentiated than the 12-40 PRO. However, if you don't have a lens close to this lens, it's an absolutely fantastic value.
