On my 70-200mm f/2.8L IS II, I can stack a Slim CPL (5mm thick like the F-Pro) onto an F-Pro UV with no mechanical vignetting.

I have been using the F-Pro's and I saw this filter and just the name ("B+W 77mm XS-Pro Digital Ultraviolet (UV) Multi-Resistant (MRC) Coated 010M Glass Filter" ) "Digital" and "XS" I didn't know what the deal was all about. I know that we can use clear instead of UV with digital, but my twisted way of thinking is that I might buy a 1v one of these days and play with film just for the fun of it.


I didn't realize it was a thin version, so what you have said may make sense for my 24mm. I will probably never use a CPL on the 70-200 because I bought it for just walking around with. My primes I would be more likely to use one on, which makes me think this. I have an F Pro on the 24mm now, and it doesn't vignette at all, however I use a CPL on it. I might go ahead and get this filter and try stacking the CPL and see if I do get vignetting on the 24mm. I always find it to be a pain switching the CPL and the main filter. So I think I will go ahead on order this filter, and put it on the 24mm and switch that filter to the new 70-200mm.
