    Accepted Solution

    Othere than protecting the lens, these filters (UV-Haze and UV) don't really do very much other than blocking some of the light reaching the sensor. Here is a short explaination: Difference between Haze and UV?

    Assisted Solution

    There isn't really a question in your post, but the difference in price is because of the different coatings, materials, amount of research and quality control processes.

    The B+W filter has a brass frame... the other 2 don't say what they are, so they are likely either plastic or aluminium. The B+W's MRC coating is also water shedding.

    If you click on the pictures in the B+W listing, customers have submitted about 4 pages of pictures of the same subjects/objects with different filters, demonstrating barely noticable (but still *there*) artifacts.

    It should probably be noted that digital sensors are not affected by UV light as film is, so really the only criteria should be strength (for protection of the front element of your lens) and lack of artifacts.

    Did you miss these
    or just picked 3 from the 600+ results for "UV filter 46mm"?

    I notice a lot of them don't really specify "glass" so I don't know how you would tell what they're actually made of without breaking them (or at least risking it). Polycarbonates like lexan would be practically unbreakable compared to glass, but the coatings stick better to glass, especially after the polishing it takes to make lexan as 'clear' as glass.

    Another consideration is how much the lens cost... it's easier to justify the more expensive filters just as protection if you pay $1000 or more for the lens.
