Polarizer for Canon 24-70 f2.8 ii

[mrkim]

I am extremely happy with my new Canon 24-70 f2.8 ii that I got during the double-dip rebate period but I still have a couple of things I need to get before making my lens "complete". I couldn't find a solid answer to my question anywhere else online or anywhere on the CR forums so I'm hoping someone here with some experience here can help me.

Does the B+W 82 mm F-pro mount Polarizer cause additional vignetting on the Canon 24-70 f2.8 ii?

Here is the specific link to the filter I am looking at purchasing. http://www.bhphotovideo.com/c/product/10890-REG/B_W_66_016117_82mm_Kaeseman_Circular_Polarizing.htmlrizing.html

Do I have to purchase the XS-Pro mount version to avoid vignetting? http://www.bhphotovideo.com/c/product/752977-REG/B_W_1066401_82mm_XS_Pro_Digital_MC.html Also, If I use the F-Pro mount polarizer with an XS-Pro mount UV/Clear filter underneath, will I see vignetting? http://www.bhphotovideo.com/c/product/756192-REG/B_W_1066126_82mm_Ultraviolet_UV_MC.html

If I can get away with not spending almost an additional 50$ for the XS-Pro mount version compared to the F-pro mount, I would like to do so (I am aware of the Nano coating on the XS-Pro mount and this is a non-issue for me as I am a hobbyist and not a professional).

Thank you for your help!

I can stack an F-Pro UV (5mm) on an XS-Pro UV (3.4mm) on my 24-70 II with no additional vignetting. So, the F-Pro CPL (7mm) should be fine. Not sure if you can stack that on an XS-Pro UV, but you shouldn't do that anyway.

Thank you for your reply Neuro!

I was hoping a regular poster such as yourself would be able to help me. Are you advising that I don't stack a XS-Pro UV with the CPL because it would reduce image quality? I ask because I don't want to juggle two different filters on and off the lens if I can leave a XS-Pro UV on all the time to ensure weather sealing is maintained.

That's the usual reason to avoid stacking filters, yes. Other than possible vignetting, it may not make a noticeable difference in IQ with good filters.
