"It's extremely wide, it's fast, it's relatively small and it even takes filters. And that's not all there is to the Laowa 10mm f/2.8 Zero-D FF. It's also Laowa's first autofocus lens, and the autofocus works really well. It's nicely made and it's sealed against the elements. The image quality is very good for such a wideangle lens, with great central sharpness. The corners are pretty good wide open and very good when stopped down. Especially impressive is the distortion, or rather the lack of it, without having to rely on in-camera corrections. The fact that it takes standard 77mm filters is a bonus for cine-work and landscape photography."
