User profile: Amateur
Cons: Difficult to manually focus (live-view for astro)
Pros: Tack-sharp for a 20mm Good coma at 2.8 Lightweight Excellent color and contrast Amazing starburst effect when stopped down
Summary: Perfect for astrophotography and landscapes. This lens is almost always in my bag. I would have to replace it if lost or damaged. I use it on both FX and DX.

Cons: Plasticky, would like finer adjustment of manual focus. The infinity focus is not at the hard stop.
Pros: While made of plastic, but it\'s good plastic and has taken a beating by me and still works well. I use it for astrophotography on a D750. Focusing is done in live view. I keep a piece of electrical tape on the focus ring and tweak the focus
Summary: A good lens, maybe not as good a choice as the Rokinon 24 for astro, but I haven\'t tried them side by side. As a general purpose wide angle, it is good. The auto focus is great in the daytime.

Cons: Slight flare, very short range of focus ring.
Pros: Very fast optics in an extremely small and light package; very good optics performance; comfortable focal length; beautiful sunstars.
Summary: Currently my favorite length on my Nikon D610 and Sony a7s. Its light and small package is so convenient and a joy to use that I do not have any word on its build quality. Very handy not only as a superb astro lens but also as for everyday use of landscape pictures. The sunstar is the most beautiful I've ever use. Although the resolution results are not that rosy on FF edges, it never really bothers me in real shootings because of its lack of coma and aberrations.

Cons: build quality, a bit to much plastic
Pros: weathersealed? Good results combined with a d750 / d800 even wide open used as a astrophotography-lens, relative low coma, thats mostly gone @ f2.8. Nice sunstars, very usable in contrajour shots. Low flare! Suberb ir-lens no hotspots on a d200 uvir. lightweight
Summary: very usable in harsh conditions, tested in NewZealand / Fiordlands under extreme wet conditions, with harsh light.
