Works just like it should, but it is impossible to put the lens cap on with it on. It mostly sits in my camera bag.
I bought 2 metal hoods, 52mm and 58mm, for my 35/2 and 50/1.4 canon lenses, after I open the box and screw the hood on lens, I found I cannot put the lens cap on the hood!!! That means I have to chose the hood or cap, but only one! What a design! I have never seen a lens hood like this. I have to leave the lens glass open to air if I screw it on?[...]
