Excerpt: This is a great manual lens with a focus as close as 1/2 inch it's almost impossible to get a poor image. I used this product for the first time at a sunflower field. Every picture taken was acceptable, very clear and crisp.
Summary: Awesome fisheye lens. Surprisingly sharp if stopped down a bit. Just be aware that this lens is completely manual, there is no mechanical or electronic coupling to the camera body. I really like that the lens can focus as close as .25 inch.

Summary: My new favorite lens. Back in the days of Nikon coolpix 950 and 990, I had a screw on fisheye lens. Terrible chromatic aberration, but I didn't care. I could get within a quarter inch of the subject and still get focus. Now I can get this once again with my SLR. Automatic focus would sure be nice.
Summary: Very interesting lens. Does exactly what I needed it to do. Only complaint is that the F Stop ring is a little "loose". Would be nicer if the stop clicks were a bit firmer. Photos are a bit soft but I expected that from such a reasonably priced lens. I'd definitely recommend it
