My 24-70 G-Master Hood is very difficult to put on when reversed. I have to force it to get it to click into place. I own 4 other Sony lenses and none have this issue, and I never had it on any Canons either. If no one else has the issue I wonder if the hood is a dud and buying a new one would solve the problem?
It's so bad that when I go to use my 24-70 for the first time at an event, I'm scared that if I don't hold the lens with one hand and the hood with the other, I might damage something while removing it. When on the normal way, the hood works as it should, although there is a bit more noticeable friction when turning the hood as compared to my other lenses.
