At face value, this 12mm fisheye lens from Samyang would be good value if it was only half-decent, due to the low price and excellent build quality. The fact it is capable of producing images with outstanding sharpness and offers a unique stereographic projection, means that this lens should be high...

It would be difficult to asses the Samyang 12 mm f/2.8 ED AS NCS Fish-eye unambiguously. On the one hand it provides a sensational image quality in the frame centre; on the other hand its resolution on the edge is hardly impressive.

sensational image quality in the frame centre,, good correction of longitudinal chromatic aberration,, no symptoms of spherical aberration,, moderate astigmatism,, negligible vignetting on APS-C/DX,, very good work against bright light.
-
-
weak image quality on the edge of the frame,, too high level of lateral chromatic aberration.

I used this lens with my Canon 5D Mark iii and I seen very nice results. I shoot this photo in the back of my house. The only negative I found is the manual focus but I can work that out.

this is the third Samyang/Rokinon lens i have purchased. i have the 8mm f/3.5 Fisheye for my Nikon D90 (converted to IR), the 14mm f/2.8 for the Nikon D750 - though it works for the D90 too (no infrared hot-spot). this lens is for the D750 and what a joy it is to use.

Excellent Lens, I purchased this lens for my Nikon D810 and it's been pretty good. I've used it on Fujifilm X-M1 with Fotodiox Nikon F to Fuji X mount and it works pretty good. Manual focus at time might be challenging, but with ultra wide angle, it's rare case.

Amazing quality for a reasonable price! ultra sharp and amazing color rendition, it's THE BEST Fisheye available for FX cameras!, you DO NOT need autofocus for a fisheye, put the focus a little before the infinity mark and stop at f/5.6 and it'll be ultra sharp with everything in focus from 1 feet...
