DO NOT BUY

Summary: DO NOT BUY. I tested this lens on a GX7. After half an hour I decided to just return it. OK, maybe my particular Samyang fisheye lens was defective but I've no reason to think so. Center sharpness was OK (if not excellent), off-center (including not all that far off center) was poor to worse. Use this lens in Aperture priority mode, shutter speed will take care of itself. That worked out OK for the most part.
Summary: This is a fairly inexpensive option for ultra wide/Fisheye for your micro 4/3rd camera. I'm using it on my Panasonic GH4 and it's great .I also have the Panasonic 8-12mm, which is an excellent zoom; but I got this due to its fixed, manual lens and extra light weight, that works great for the readily crop-able, 4K image coming from GH4 while on a steadicam! Ultra light rig and awesome for un and gun.
Excerpt: I just spent a few hours shooting with this around my house, and I love it. It's reasonably sharp, got a huge field of view, and is a fun lens to have on hand. It's very old-school. Manual focus, manual aperture, and no information sent back to the camera. Either I had to be in full manual, or my camera (Olympus E-P2) handled exposure by adjusting the ISO automatically.
Summary: I personally like this lens for a very wide field of view. Distorted, Yes, it's a fisheye. I use it on an Olympus OM-D E-M5, and really just have to play with some small adjustment. As a matter of fact, it will work on this camera when put on, with out a fuss. The EM-5 settings can make it play a little better, but most adjustments will not improve your shooting. There is a way to magnify focus, and that's what I use to help out the image by just checking.
Summary: I just want to point out that this lens is sold under at least three different brand names: Samyang, Bower , and Rokinon . (The other reviewer mentioned ProOptic, but I didn't find that in an Amazon search, so I guess it's no longer sold under that name.) They're all the same lens, and prices vary quite a bit, so shop around. The Rokinon version has the most reviews, so go there to learn more.
Summary: Not everyone need a fisheye. Foe me it is more a fun lens than a serious optical instrument. When I got this little guy from Samyang, I was really surprised at how good the image quality is. The build quality is very good , tight fit and smooth operation. Focus is a little fiddlely, but set at f5.6 infinity, it is pretty sharp all the way. Out doors , it becomes an ultra quick point and shoot, no focus lag at all. Perfect for arms out self portraits if framed correctly.
