    Default Review of commonly used UV filters

    Hi,

    With the constant asking of questions like
    -"Which UV filter is best? "
    -"Will a UV filter degrade my image?"
    And a personal desire to see the degree various UV filters will degrade my image, I have done a small experiment.
    I hope this is the right place for me to publish my findings.

    Filters that were tested (I only own these, tested on 1 sample of each) :
    - No Filter (as reference)
    - Hoya HMC UV(N) Japan
    - B+W 010 1x MC, Multi Resistant
    - Hoya UV Philipines
    - Nikon L37C


    Procedure :
    Camera was tripod mounted, 1/60 f8 on a 80-200 AFS @ 200mm, flash on manual, Auto WB. Sharpening off.

    Target image :


    Centre area was magified 300% and cropped, the cropped image was doubled dpi no sharpening, no correction was done .
    Results :



    Original 100% cropped can be viewed at:

    B+W : http://img216.imageshack.us/img216/1...4893mrc8mw.jpg

    Nikon L37C : http://img216.imageshack.us/img216/6...895l37c4ad.jpg

    I leave the conclusion open for discussion ...

    Can loan you one... but I'll bet the results are the same as no-filter used.

    From your test, seems like the L37c is the best!

    No surprises here

    I think the B+W MRC is second? Right?

    Colour redition the L37C's better than the B+W, but no filter is best, I think NC77 would achieve the same as no filter

    Not the best day for testing today, the torture test is shooting into the light, to check for flare resistance and loss of contrast, it's what separates the men from the boys.

    With so much pouring rain, and not wanting to risk getting the hair wet or the precious gear wet, so got time to carry out these tests.

    Good to know that there is some difference and we are able to see the difference, if at all. But I wonder if it makes a significant difference in the photo if we print to say 4R, 8R or a little bigger.
    I love big car, big house, big lenses, but small apertures.
