While it is expensive, go with the
B+W 62mm UVA (Ultra Violet) Haze MRC Filter #010
version instead with the MRC coating.
There are two aspects to a protective filter, one is the degree in which the filter does not give any ghosting, minimizes flare, while keeping an optically pure path.
This and other multi-coated filters will do this fine, such as hoya, sigma, b+w (not tiffen, bower, and brand x)
The next step is durability.
I have several sigma filters, and while they are optically great, the coating on them is very fragile, i.e., they gets knicks in the coating from even a bit of dust it seems, maybe some wind blew a bit of sand, but very fragile.
I have not had the couple hoyas long enough to tell, seem better than the sigmas in terms of durability, however from reviews i have read it is an issue.
I did some research into the MRC coating that some of the B+W filters have, which the manufacturer claims is harder than glass. I have this same type of coating on a pair of eyeglasses and it is the first eyeglasses i have had that do not get scratched (over 2+ years).
Basically, if you want the filter to still be in good shape over time, then get the hardened coating instead, which for this filter is the
B+W 62mm UVA (Ultra Violet) Haze MRC Filter #010
(Notice the MRC as part of the product name), it cost about $20 more, but what to do?
