I was watching this fisheye for a long time and finally took the plunge.It's definitely a niche lens, but you probably already know that if you want one. It's very well made, nice heavy feel, but compact and fits well on e mount cameras.

This lens is very sharp and I have been using the lens on the Canon M5 at ƒ5.6 manually pre-focused. The weather has been pretty bad for most of the time I've had it, so I'm not as practiced with it as I hoped I would be at this point.

Had the rokinon 8mm f3.5 lens and it wasnt nearly as sharp as i had hoped, this 8mm f2.8 lens is what id hoped for. Found that at f5.6 to f8 focused between a meter and infinity its sharp close and far.

I used the lens for ultra wide artistic shots. Perfect with my a6300. Very cheap, but the built quality is very high. However, it is heavier than I expected.Images are really sharp if you don't forget to focus manually.I love the small size and the lens hood is perfect.

Very easy to use. Extremely sharp! I would buy this lens again.

This review refers to the version II lens for the Canon mount. The lens is sharp wide open from center to corners which is simply amazing. Stereo graphic projection allows to produce very nice images which look great (if you are careful) even without defishing.

All good, and exactly what i want!

This thing is a lot of fun, almost a 180 fisheye on a cropped sensor.
