What UV filter for new 70-200mm (77mm filter size)?

[Dylan777]

+1 on no filter at all.  There are no filters for the front elements of supertelephotos and ultrawides.  Image quality is my top proirity and slapping a $60 on a $3000 lens makes no sense to me.

Have you ever try one of these?

There are no filters for the front elements of supertelephotos...

No, but there's a filter inside them, and Canon says you should always have a filter inside them.  Does that degrade their IQ?

none...  leave your lens hood on to protect your lens, the more glass you add the more you reduce the quality of your lens

-1.....not when you use high quality filter. With B&W Clear, I don't see the effect in my photos.

I agree with you...to all the goys that are saying no filter..when I get my lens I will shoot two raw files off a tripod..one with a B&W MRC filter and one without...and you have to tell me which is which...doubtful that anyone could. truly...
