In contrast to the excellent clamp for my Macro (100 / 2.8 L IS) I'm not quite satisfied with this clamp. Unfortunately, the clamp does not fit exactly. If the clamp screw is fully closed, the lens still has game and can be rotated. Especially if my heavy 7D sits with battery grip at the other end. Processing is otherwise very good. The aluminum is processed cleanly and he makes a good impression textured paint, the color fits (almost) perfect for lens. Another point of criticism: The clamp has no protection against complete unfolding. This can, however, in the truly fair price do not expect. So when handling just a little caution is advised. I struggle just with me if I should exchange the clamp Despite the slightly longer delivery times. Because they should mechanically fit the minimum requirement already.
