    Rusty, that depends entirely upon the environment. Sometimes I go months without ever needing of cleaning my "unprotected" lens. Ohter times, like in high dust or salt spray areas, I might need to clean the lens once every couple of hours. By clean, I often just blow it off with my mouth and only do more if I can't keep the saliva in my mouth. In terms of a real cleaning with a brush, solution, and lens paper... very rarely, maybe even extremely rarely.

    To clean my lens I go through a car wash!

    Yes, this is quite important and I would say about every month or so. But this of course depends on how often you use the camera.

    Thanks,
    I use a lens cap while I am walking into town but it comes off and goes in my pocket as soon as I start shooting. You can't be taking the lens cap on and off between pictures, can you.

    On the UV filter thing, I theoretically use them but in real life I just cannot afford one for each lens - it would eat into my film budget too much.

    I only use protective filters when shooting at the beach, where salt spray settles on everything 24 hours a day. Otherwise, I always use a lens hood. Why put a $20 piece of glass in front of a $600 lens? It increases flare and unwanted reflections. I've never damaged a lens, even when using 35mm gear daily for newspaper work. When shooting, all my lenses get carried face-down in a padded bag with the lens hood on, no cap or filter, back cap on. I clean them when they need cleaning, which is not that often, unless I've been out in the aforementioned salt spray.

    Does it make a noticeable difference? Test the lens with and without a filter, in flat light and in high-flare conditions. See which you prefer.

    How can I stand up for both Ann and BrianShaw without appearing to waffle?

    For filters:
    I like to get lenses that had UV filters on them, even if the filter is wrecked... The glass underneath is pristine. And I like to clean lenses that had UV filters on them, because a puff of air is all it takes. And if the filter is dirty I can clean it with the edge of a t-shirt because it's just a filter.

    For lens hoods:
    I don't know of any shots ruined by filters, but clearly some could have used a lens hood. Taking off a filter removes two reflective surfaces... But when a lens hood eliminates a reflection, it removes it from all the surfaces.

    Against filters:
    Two reflective surfaces that can degrade image quality. Harder to close some camera cases. Harder to adjust aperture of some lenses. Potential for vignetting when combined with lens hood.

    If in doubt, if you think it will ruin a picture, take the filter off! You're paying attention to what you are doing, unless there is a sandstorm or ocean mist, you will not ruin the lens. Then you can put it back on when you toss the camera in the back of the car - where the real danger lies.

    More lenses have been damaged by zealous cleaning than from any accident. Loose dust can be blow off using a baby ear syinge. The only time to clean a lens is when there is a greasy mark on it.

    I clean the front and back very carefully before any important shoot. But I allow a little dust to accumulate on a trip where I know I might be less careful cleaning. When I am out, I will clean if a fingerprint appears - those degrade quality and can be harder to clean if you postpone it.

    I carry my lenses without front lens caps with a clear multi- coated protection filter on them and the hood fitted face down in my camera bag with just a back cap on them I never clean the front elements of the lenses they are clean already, I only clean the protection filters once in a while.
