Objective Filter Information

[richardpcrowe]

Has there been any objective testing between the following high-grade filters. I am specifically looking for a 77mm filter that is NOT a super-thin filter and which has a thread on the front of the filter.

B&W MRC
B&W Kaesmann MRC
These are manufactered by Schneider

Hoya Multi-coated HMC (gray box)
Hoya Super Multi-Coated SMC (black box)
Hoya Super HMC Pro-1 (blue box)
These are manufactured by Tokina (I believe)

I use top line lenses (mostly "L" glass) and I am willing to pay the extra for a first rate filter but, I would like objective rather than subjective information on the filter that I will buy. The general pricing of the above filters (excepting the Hoya HMC which is less expensive and the Kaesmann which is considerably more expensive) are fairly close.
