This Automatic Macro Extension tube did not fit the camera and the lenses well. I have to hold the lens in a special position in order for the camera to communicate with the lens. It simply can't be used.

Though cheap, these are not worth it. The metal interface is so badly machined that the rings are not only loose where they contact the camera and lens, but also between the two rings themselves. The electrical contacts therefore keep wobbling out of contact. A better made manual set of rings would be less annoying and easier to use.

Construction seems okay but loose fit on camera causing some electrical connection problems at times

I bought one - and as others have testified - it damaged the electrical connections of the lens attached to it as the contact pins would not retract safely. This may not be a uniform problem - but I sincerely regret having bought this adapter and have switched close-up filters instead

This adapter destroy the lens electrical connector!
