Summary: This 77mm UV haze resides on a Canon L series lens. As with the other B+W filters that I use, this one is of excellent quality. Why would anyone skimp on a cheap filter for an expensive lens? The great quality of the B+W filters is worth the price.
Summary: You can spend less, but why would you put a cheap filter over your high quality lens? That would be like framing a print, then using cloudy, fogged up glass in the frame. You won't regret spending the $.
Summary: I wish I would have bought B+W filters for my other lenses -- they don't compare to B+W. No haze whatsoever, and you can feel the quality of the filter just by the weight of it. I will never buy any other filter but B+W.
Summary: I put one on all my lenses. It's a must, and only comes off when it needs to for lighting reasons, or for long exposures when reflection between the lens and the filter show up in the image.Ken Rockwell calls this a prophylactic filter. Better to break/scratch/or otherwise ruin a [$] filter than any lens. Keep your lenses protected!
Summary: This filter is permanently attached to a Canon EF 24-70mm f/2.8L USM lens as a protection filter. Outstanding clarity and superb quality. The filter glass is threaded into the metal filter collar and very stable. This translates to no rattling or slip like cheaper made filters, and is typical of B+W products. Planning to buy an identical filter for my next lens purchase (Canon 70-200 f/2.8 IS lens). This filter would work just as well with Nikon 77mm lenses.
Summary: I am very new to photography and purchased this for my 70 - 200mm lens and I am glad that I did. My three year old has already put his fingerprint on the filter and I was glad it was the filter and not the lens.
