I've never noticed it. If you're like me and shoot wide open all the time then this will not be of issue at all. Comes with a variable ND filter (so you can shoot wide open all day). This has been on since I got it so the element is perfect.
Comes with all the original bits. I added the focussing tab which really helps. It's got quite a long throw so focussing without is a bit of an effort.
