Using UV filter for lens protection

    I'll be taking delivery of a Canon 10-22mm in the next few days. This
    will easily be the most expensive lens I own. I was wondering what
    everyone thought of the practice of using a UV filter to protect the
    lens? I know there may be a risk of vignetting at 10mm although I
    believe some filters are quite thin.

    Yes You can get very slim filters now and its certainly worth it to use a uv
    or even a plane glass one That some makers are doing think I would be happy
    with the uv.
    If you notice any vignetting at 10mm you can always unscrew it But it will
    probably cause nomore then what may be present in the lens at full stretch

    I have always fitted a UV, or Skylight filter to every. Of course it's
    meant I've never even damaged a filter as yet, but that could be all
    part of sod's law!

    You can get around the vignetting, which seems pretty common on many
    DSLR wide angle lenses. Try not to use a wide aperture at the shortest
    zoom. Photoshop (even Elements can) can also deal with it at the RAW
    processing stage too.

  4. Occasionally flare can be a problem with filters but I always use a
    UV/Skylight filter and just take it off when I notice that flare is a

    I think Andy has probably summed it up when he said he's never damaged a
    filter. IMHO, it's not worth it. The idea of always fitting a 'protection'
    filter was probably started by the retailers to increase their profits. I
    used to use them until I really thought about why I did it, then I stopped
    and haven't used one for years.

    A lens hood is a good idea and also gives some protection from knocks etc.
    Nothing will protect a lens from being dropped. Any dust/dirt can usually be
    cleaned off with a brush or lens tissue. The only time a filter might be
    useful is to protect from sea spray/salt etc. Bear in mind that, having
    spent all that money on the lens, do you really want to degrade the image by
    putting another piece of glass in front of it?

    Yes, and I have my camera kit insured, but I don't expect to have to make a

    The difference is, a filter will always degrade the image to some extent.
    Can you accept that more than the risk of damage. I will accept it if the
    filter is doing some good - maybe to improve the image in other ways or, as
    I already said, in environments like by the sea, but generally I won't.

    It depends on what you perceive the filter is protecting against and whether
    you are prepared to accept the risk.

    Thanks to everyone who replied. Obviously there isn't one consensus but
    I have given it some further thought.

    I tend to be quite careful with my camera and lenses. I haven't managed
    to damage one yet. I'll probably give the filter a miss and just rely on
    the lens hood to give some degree of protection against knocks etc.

  9. Just avoid sandstorms and any event that may spray gunk into the lens :)

    If I was using the lens in that sort of environment, I'd probably buy a
    filter. Trouble is, I wouldn't want to buy a cheap filter that would
    compromise image quality and I wouldn't want to lash out on an expensive
    filter if I was going to use it infrequently :)

    I have Hoya filters on all my Canon lenses( FD/EOS) ,I see them as safety
    glasses for camera lenses.

    I drooped my old 300mm FD lens on concrete while on holiday 3 years ago.The
    filter is no more , but the lens being plastic survived as did the fromt
    element of the lens.

    This is the first lens I have ever drooped in over 30 years of
    photography ,but you can bet that my eos lenses have Hoya filters on them

  12. If you were using the camera in those conditions, there's more than the
    lens surface to worry about, especially the adjustment rings. If they
    start grating or sticking, you've still got problems. Put it in a
    polythene bag (and don't take any photos!!!).

  13. You can still take photos with the lens poking out of a polythene bag, I've
    done it many times with an elastic band holding the polythene tight.
