Are there any disadvantages to leaving my circular polarizing filter on my 24-70L 2.8 at all times? My current setup has the polarizing filter directly attached to the lens with a clear filter (the one I bought with the lens just to protect the glass) on top of that. I figured why not protect the polarizing filter too. The immediate disadvantage I can think of is that it makes it impractical to take off the polarizing filter for use on my 70-200L 2.8 II. But are there others?
Thanks in advance.
