Title: Not Compatible With All Lenses
Review: This teleconverter was given to me as a gift, and I eagerly looked forward to using it. However, when I connected it between my Nikon D300 and my Nikon 70-200 f/2.8 lens, absolutely nothing happened. No auto-focus. So I disconnected it and then reconnected and still no autofocus ability. I then confirmed all settings and it still would not work. So I went to manual mode, and was able to zoom in and out by hand, but when I went to take a picture, the picture was solid black--no picture came through.So if you are considering this product for a Nikon D300, you may want to pass.
