B+W UV Filter Question...

What’s the difference in B+W Multi-Resistant Coating vs. The Non-MRC ?

Is it worth pay the extra money for the MRC?

In one word: yes.

The non-MRC is single-coated, and although it is a quality single coated filter, it can't beat a multi-coated filter, which is what you really, really want for digital.

HTH, kind regards, Wim

Ditto what Wim said...

We all agree; if you are going to use a filter go for MRC.

Yep, get the MRC.

MRC is the only option you should consider. Pretend they don't even offer a non-MRC.

Some of the B+W non-MRC filters are multi-coated, and some are uncoated (yep, I've had a PL-TOP filter that was uncoated). I haven't heard about single-coated B+W's. Basically, MRC filters are much easier to clean because outer coating is "water-repellent". Considering the negligible price difference, I'd get the MRC.

B+W's non-MRC filters are single coated, on both sides of the filter.

MRCs are multi-coated, and have the hardened water, grease and other substances repellant outer coating.

I don't know, but I get a bit of a chuckle out of these "water repellent" coatings. It's a PIECE OF GLASS. Of course it's water repellent.

I've never had a problem cleaning lens elements or filters (even "troublesome" Hoya and Cokin filters). I've been using the same stuff for 25 years; Formula MC and lens tissue.

They are actually much easier to clean; they don't only repel water, but also grease and all kinds of other muck, plus the coating is scratch resistant to a rather large degree.

The owner of one of my preferred stores routinely shows off by using a water resistant marker on an MRC-coated filter vs a non-MRC one. The writing doesn't stick to the MRC coating, it does to the other one, and is rather hard to remove from the non-MRC filter.

Even so, the main reason to use it for me is the fact that it is multi- rather than single-coated.

Kind regards, Wim

Interesting example, Wim. I'm sure the coating helps. I've never had a problem cleaning a filter so I guess I never noticed... Often enough though, I shoot in the rain and the filter definitely stays drier than the viewfinder!

Heliopan filters also offer this coating. From their brochure, "Dust and moisture repellent top coating on each side of the SH-PMC coated filters for easy cleaning and longest life."

But I agree though - the multi-coating is what counts.
