Just wondering from pure quality perspective, which one is better? The original single coated Rollei 30.5 filter has fairly large outer diameter which can readily take a Kodak canister cap, while the B+W filter is too small for that. However, since the original Rollei filter is harder to clean than B+W MRC, I am thinking about switching to MRC. Any thought? Thanks in advance.
