How about this B&W?
Nope, this one. The one you linked is the F-Pro mount, and you want the XS-Pro mount. The F-Pro causes a slight increase in optical vignetting on the 70-200/2.8L IS II (unusual for a standard filter to vignette on a telephoto lens, but it does on this one - I've checked it myself).I agree with Neuro...go with the clear, MRC, brass ring...they are the best...You do not need the UV protection on a digital camera ...that is a factor with film...took me a while to break that habit.
You don't need UV for digital, true. But it doesn't hurt, either. Depending on filter diameter, vendor, and geography, sometimes the UV version (010) is cheaper, sometimes the Clear (007) is cheaper. On amazon.com, the 77mm XS-Pro UV is $80, and the 77mm XS-Pro Clear is $115. Since there's no optical difference for a dSLR, I recommend getting whichever one is cheaper.
WOW Neuro..I have not noticed any vignetting with my 77mm F-Pro..but I will take you word for it and give a closer look the next time I shoot....is the vignetting more at a certain focal length of the lens?
I just checked some images I shot two weeks ago at 175mm and 200mm with a 1.4xIII on the lens and could see no signs of vignetting.
