I'm reading through this thread and have some questions about the B+W line of 82mm Clear filters, of which I see three on B&H:
(A) B+W 82mm XS-Pro Clear MRC-Nano 007 [$121.95]
(B) B+W 82mm 007M Clear MRC Filter [$100.66]
(C) B+W 82mm Clear Slim MRC 007M filter [$139.99]My questions are:1)
I know that (C) is "thin." I know that (B) is "standard." But what is (A), thin or standard?2)
I see this warning in the item description for (A) on B&H's site:
This filter ring's outside diameter is slightly larger than the actual thread size, and because of this you may be unable to attach the lens manufacturer's bayonet-mounted lens hood to the lens while using this filter. This is dependent on your specific lens and how thick the front rim of the lens is; with thinner, low-profile lenses usually being affected more.
Does this lens hood problem affect the 82mm XS-Pro on the 24-70 f/2.8 II? And is this a problem with the 77mm XS-Pro on the 70-200 f/2.8 II?3)
I see people in the thread mentioning a 82mm "F-Pro" filter. Is that referring to (B), or something else entirely? I can't seem to find a mention of "F-Pro" on B&H.4)
Is stacking a circular polarizer filter on top of an existing Clear/UV filter something that people commonly do? Or are you supposed to take off the Clear/UV filter first, then screw on the circular polarizer?5)
Is (A) too thin to stack another filter on top of it?
