Do you think canon is releasing new version of EF 24-70mm f/2.8L II USM?

It is true that in most situations you will never notice a drop in IQ with a good B+W filter. There are certain situations where I have noticed the difference and most of the time it is when I am doing Macro, Landscapes and some Wildlife. Pixel Peeping is required and it is one of my bad habits.

A thing to consider would be how you handle your equipment. John mentioned getting brushed with leaves when he is carrying it on a BR strap. If I put the lens at my side the cap and filter are back on. If a person likes to walk with the camera at ready like this I think a filter would be a good idea.

I think that the front element of lenses is a bit tougher than we give them credit. I know I am over cautious with my lenses. From what I have seen though I think the front element is tougher than the filter, if the filter doesn't get damaged in a hit I doubt the element would either.

I have been doing it this way over a year now, all my lenses front elements still look brand new.
