B + W 55mm UV Protection Filter (010) for Camera Lens – Standard Mount (F-PRO), E Coating, 2 Layers Resistant Coating, Photography Filter, 55 mm, Clear Protector

Its a B and W filter, simply put. They are well known for their quality. I have it on a Canon 70-200 2.8 L, and I see no degradation in image quality. Overall a good buy.

Seit dem ich fotografiere habe ich durchwegs positive Erfahrungen mit B+W Filtern von Schneider gemacht - als Konsequenz kaufe ich keine anderen mehr, auch wenn dazu der Extra-Euro fällig wird.

Thin, offers great protection. Ive always been a fan of B+W filters for their high quality. The filter protects your lens element without affecting image quality.

I purchased this product as a newbie. I read quite a few reviews and discussions as to whether or not its needed. I keep it on my 17-55 lens most of the time for protection sake. I honestly cant say that I notice any difference when its on or off. It is a bit of a hassle taking it off (unscrewing it) and replacing it with another filter. Its not something that happens instantly, so hopefully theres no hurry when youre making the change. Someday Ill have to compare some pics with it on and off to see if there is any difference in sharpness, etc.

I did not realise that these filters were manufactured in Germany by Schneider Kreuznach until I read the details on the box of the first one I purchased. This company at one time supplied camera lenses to high end makes such as Hasselblad, Kodak Retina, Rolleiflex and even Leica. They still make best quality lenses for the cinematic and large format camera industry so there is no doubting their pedigree as optical glassware manufacturers. I now use these filters on my Leica cameras because they are easier to obtain and significantly less cost for the same, if not better, quality. A 52mm Leica filter costs £78 as opposed to a B + W at £46, though Leica in the UK at any rate, seem to have dropped their prices somewhat. Previously a new E 39 Leica filter was costing £120. The B + W filter has Nano coating to reduce the adherence of particles and water drops and multi coating on both sides so no reduction in photographic performance for the lower price.

This fits my Olympus 12-40 f2.8 perfectly, and causes no vignetting at the extreme wide angle setting. Ive tested the lens with and without the filter and see no difference in sharpness or color, but it sure makes me feel better having it on, especially since I live next to the ocean.

Works as advertised.

Great product. These are the very best filters and reasonably priced too! I am an optical coating engineer and these are my filters of choice.

Fits well under the hood of my sony 35mm lens

I bought this to use with a Fujifilm X100s. The filter performed well, pictures were fine. But the camera case is too restrictive to allow the filter to be permanently attached. Not a knock on the filter, but rather an incompatibility issue caused by the camera case.
