Summary: I followed the instructions to place the connector on the camera. Then connect the lense. It fit great and focused will, but when I tried to remove the lens would not release from the connector. Removed connector for camera and lens is stripped on the connector.

Summary: Horrible product. Lens is Not compatible with Nikon D3x camera as advertised. And they make you pay for shipping it back. They have a 15% restocking fee and they also will deduct the original shipping cost if it was free.
Summary: I purchased this as a gift for my wife. For a manually operated zoom lens, this one is very good. You'd pay $5000 for one of these that are fully automated, so it's a good compromise. We took some very good photos of the lunar eclipse last spring with it.
Summary: Zooming and Focusing is a task when it should not be. Has horrible balance when put on a tripod. If you have ANYTHING moving in the picture it messes the whole thing up. Picture quality is even downgraded a lot ( No matter how much light there is in the picture ) It isn't even worth the $145 I paid...
