Interesting, I got a few 77mm B+W, just now purposely took each one out and checked, all those I bought from CP are "heavier" (brass)and there is only 1 pc I bought from HKG and is "lighter" (alu?), when holding each one side by side can easily feel the weight difference. The marking are as per the TS photo on the 1st post.i think it was mentioned b4 somewhere in CS... can't seem to find the thread. :dunno:
the brass ring version sold by CP (which, IIRC, is the official dealer of B+W in SG) comes from Germany and is meant for our market.
the aluminium (lighter) version is manufactured (IIRC, according to the old thread) in china and meant for the China market. both are, by right, B+W products, just for different markets.
if you got the aluminium version, it means it is the grey market type not brought in by CP.
hi guys, i made the refund just this afternoon but had a little argument with the shop.
optically, you can tell the difference based on the reflected light coming from any ceiling lighting, fluorescent light bulb to be exact.
bought the brass version at John 3:16 for S$15 more than the alu version.
OT: thanks alot to Samuel Gan of John 3:16 for being so kind & helpful. :thumbsup::thumbsup::thumbsup:

Stumbled upon it when I was looking at come ebay users questioning about the authenticity of certain B+W filters originating out of Asia.

Another email from Schneider
"Tony,
Maxsaver.com is not an authorized Schneider dealer, therefore, I can not comment on their products.
I can only suggest purchasing from an authorized Schneider dealer to be assured of receiving genuine B+W product and a U.S. warranty through Schneider Optics, Inc..
http://www.schneideroptics.com/dealers/dealers.htm (http://www.photography-on-the.net/forum/)
FYI: B&H Photo does not purchase B+W filters from us. As a result, there is no warranty through SOI.
BR, Kevin."
B+W Standard Filter Mount F-Pro
Compared to the earlier B+W standard filter mount, the B+W Standard Filter Mount F-Pro has been improved considerably.
While maintaining the excellent quality of materials, fabrication, and high mechanical stability, the new F-Pro mount has become thinner, so that now it can also be used on many wide-angle lenses without the danger of vignetting. An exact focal length limitation cannot be stated, because vignetting depends not only on the height of the filter mount, but also on the design of the front of the lens. Nevertheless, the following can serve as a guide: The B+W standard filter mount F-Pro can be used without vignetting on 35 mm camera lenses with focal lengths of 35 mm, most 28 mm lenses, and in many cases even on 24 mm lenses.
Another advantage of the new F-Pro filter mount is its modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back. This prevents the retaining ring from being accidentally loosened during the removal of an additional filter or a lens hood that has been screwed in too tightly.
Hey guys, I was just curious, has anyone ever encountered a MRC filter with no MRC imprinting on the inside of the ring (though it has everything else)? But it has on the box. I got it 2nd hand, wonder if the seller swapped it or if its genuinely like that?
I think you bought the non MRC version which is not multi coated
Lens filter is one product that has one of the largest % profit for manufacturers and retailers. Being small, stocking is a breeze.
There are fakes one floating in the market. Just be careful. If you go to China, and you have money, you can make a shipment of filters and you can dictate any brand and any wordings onto them. Making fakes is really is that simple.
As for optic quality, the difference is so minimal (between the fake and the real) that it is hard to judge by the picture quality. Lens has its original coating and so the additional coating on the filter is supposed to have very minimal effect on Image Quality.
My personal take is to get the brass ones. It helps protect the lens in the even of a hard knock. When a lens is knocked, the lens shade will be the first to dislodge, leaving your filter as the next form of protection. You already paid so much for a ring, why compromise? May as well get Hoya...
