Summary: For some personal background, I have five cameras only one of which is an SLR. I buy and sell cameras all the time perpetually looking for the Holy Grail. Though more a picture taker than a photographer, I was intrigued by the possibilities of a fisheye even though I'd have to abandon my automatic...
Summary: I haven't had a fisheye in years. They can be a ton of fun and I am happy to have one back in my bag. I'm using this with my OM-D E-M10. Lack of AF is not missed. The optical and build quality are excellent, especially considering the low cost. Highly recommended!
Summary: It is definitely a sharp lens. The only thing I have to complain about is how hard the focus ring is. I definitely recommend the lens, especially if you plan on getting the 9-18mm lens just for its wide angle at 9mm.
Summary: I was in the market for a new fun Ultra Wide Angle lens for my recently growing Micro 4/3 system. Works extremely well on my Olympus OM-D with no chromatic aberrations that I can see and is sharp even at wide open.
Adding to the chorus - this is a very fun lens, and sharp.

Summary: I didn't think I dug the distortion of a fisheye so I resisted buying this for my M4/3 set up, despite reading lots of positive reviews. I got it for around $200 on a Black Friday sale and I'm very glad I did. I recommend it to anyone building an M4/3 kit.
