The Lens Hood LH-49 is easy to mount and take off again, but keeps mounted still very good. You can be completely backwards on the lens (60mm Macro) move and then blocks the access to the manual focus ring of the lens. Is in autofocus use irrelevant without manual adjustment. I think this is also pushing back rather intended for the transport and for very practical. The panel also makes a high impression of a plastic part. However, the price is outrageous for plastic! For that I give 2 points deduction! 20.00 would be a fair price.
