The image quality with this lens attachment isn't stunning, but what do you expect for such a low price? There's lots of blur and chromatic aberration around the periphery of the image--much more so than in a more expensive lens. Some of that can be corrected in an photo manipulation program (Photoshop, or GIMP for those of us who like free software). I get the best results with manual focus and the image stabilization turned off (I've tested it so far with a Canon 18-55mm EFS lens). It's a fun lens for the occasional creative shot--I'd never use a "real" fisheye lens enough to justify the cost. Good build quality, although the downside is that to attach it to the 58-mm threads on my lens, I need to screw the included adapter onto it. You can't store the lens with adapter on it, because the included cap won't fit on it, so it's slightly more cumbersome to take on and off than if they'd just made it 58 mm.
As a side note, you can unscrew the 0.35x macro lens from the back, add it to your camera's lens and get a serviceable, if not great, macro lens. Not terribly impressive, but it's an easy enough way to dip your toe into macro waters if you haven't before.
As a final note, I'm horrified by the reviews here of people disappointed because they thought this was a standalone lens they were going to attach to their camera, rather than a lens attachment that screws on to the filter threads of your lens. How do you guys function in the real world? Do you buy a car and then gripe that act all mystified and upset when you learn you have to also buy fuel to put in it? Seriously, you didn't notice any of the usual specs for a lens stating what sort of mounts you could use? Sheesh!
