It seems to be a bit too large as it is not attaching well to the lens. It feels somehow“loose”.
Dimensions are good. It is easy to screw on the lens boby. But the protector is not fixed in the end position. There are 2 ratchets mount on springs. Shape of these ratchets are not sharp and the lock system using springs doesnt work well. So the protector is not fixed in end position on lens body.
