Other Thoughts:I Received this today and upon opening the package was very pleasantly surprised at the build quality. Very well made and my lens fit snug to the camera after is was applied. As others have said, once on this is hard to get off. Due to the price I am going to order one for each of my lenses.
Other Thoughts:I just bought one of these and took to a camera swap and bought an old nikon lens and this works amazing. i love it. I understand people saying it might get stuck and the little pin that holds it on will probably break after a hundred times of taking on and off cameras. But im just going to buy one for each of my lens' and at 13 bucks a pop thats way doable. Definitely better than the Canon FD to EOS adapter. Night and Day.
Other Thoughts:I am using this adapter for Nikon lens and it works very well. It can be removed by rotating the adapter while keeping the lever pressed. The link is tight with no play. What else I can wish for less than $15. By the way standard shipping was very good and took exactly 5 days.
