I was a bit hesitant at first to purchase this Opteka lens 'cause there weren't many reviews out there. But since purchasing it last week (it arrived well before the estimated delivery time!), I'm so happy with it. It does exactly what it says it does, it takes great fish eye shots, fits right into my Nikon D80, plus 47th Street Photo threw in an extra gift: a cleaning kit and a mini tripod! If anyone's thinking about buying one, I strongly urge you to, it's money well spent!
