Negative Positive
Title: It works pretty good, just a few niggles.
Review: I prefer the standard twist hood mounts, but as the nifty 50 doesn't have one the mechanism this uses is ok. As was already stated it is a bit shallow. The retention buttons annoy me a bit because I tend to squish the hood as I'm trying to take it off which makes it harder to take off, but they did good for what they had. I do wonder why canon couldn't make an adapter with standard twist instead of this though.4 stars due to shallowness and the odd mount.
Is the review positive or negative?
