I didn't know how I would like a fisheye lens but my initial reaction is that it is more useful than I would have thought. Definitely requires thoughtful application but that's a good thing for any serious photographer.

Probably not a lens I'll use everyday but sure love the end result. Very sharp, just fun to play with. Also I appreciate the lens hood and it's design, it fits over the lens which protrudes a little and also the small lens hood. Also, the lens it self is very compact.

Great results with the Olympus EM1 ii in-camera defishing!

I am using this on a Panasonic Lumix G9 and it is terrific. Autofocus works, aperture is controlled by the camera, and Body IS works, which is all you need to hand hold an 8mm lens. Sharp corner to corner, and no flare even when the sun is in the frame.

Hands down this is the nicest full-frame fisheye I have used. If you want the best quality fisheye for MFT, look no further. I have the Panasonic 8mm f/3.5 which suffers from flare. The Panasonic is lighter, but the Olympus is still way lighter than a full-frame camera lens.

Its awesome. As described.

This lens is very sharp and very fast which makes it great for low light photography, especially Milky Way/star photos. It is also very wide and the fisheye makes it a lens that isn't appropriate for every situation. But when you can use it, it is Awesome! Also maintains the small m43 form factor.

I got the Samyang 7.5 mm fisheye a few months ago and found I very much liked what it could do, if not how difficult it was to handle. The performance of the Olympus 8 mm has been as big an improvement as the price would suggest, in the few weeks I have had it.

The lens feels solid just like all Olympus pro lenses. It is very sharp, great for interior, landscape, and sports photography (up close). I would highly recommend this lens.

A great addition to the lens collection. Works as advertised, great results shooting ordinary scenes with a new look. Great on night sky. Use software to crop larger picture for great effects!
