Summary: Really not sure how anyone could give this anything short of a five star rating because it's a perfect fit. The quality of the lens is as good as if it came built on the camera - nice weight and balance with bigger battery. It screws in with ease to the 37mm thread on the front of the camera. When widened fully out the 'fish eye' effect is BARELY noticeable, if at all really, unless you really pause and compare.
Pros: Crisp Image, Easy To Use, Interfaces Well With Camcorder
Summary: I purchased this to increase the visual range on my Sony HVR-HD1000. I found the original range to be slightly narrow, this lens corrected that issue. it was easy to intall, it screwed on top on the existing lens. I didn't have to take the oriignal lens off.
Pros: Attractive Design, Easy To Set Up, Great Picture
