D70 Silly Question

    The D70 came with a "lens hood" that screws on over the kit lens. When
    do I use this, on sunny days to reduce sun glare?

    I use lens hoods at all times. More for protection of the front lens element
    than to combat glare - although they do that well, too.

    Add a UV filter for added protection and you can forget the lens cover.

    Basically, yes.

    Another answer:

    Always, except when using the built-in flash.

    Advantages of lens hood:

    - Reduces glare from the sun or *any* light source.
    - Helps protect front element from scratches / fingerprints etc
    *without* adding another layer of murky glass to photograph through.

    Disadvantages of lens hood:

    - Slightly more complex operation to remove & fit lens cap.
    - Rotating filters such as polarizers can be a pain to access.
    - Can cast shadows of the flash when it's being used, in particular
    the built-in flash.

    The D70 kit lens hood (due to the wide-angle part of the zoom) isn't
    as substantial as many of the longer zooms have.

    One day we will have a self-retracting lens hoods that adjust in line
    with the zoom.

    I think Sheldon meant to say "lens hood" rather than lens cover.

    And I think he is mistaken. The hood is a useful adjunct in nearly every
    imaginable circumstance, except storing the lens in a custom-fit case.
    It might not fit with the hood on. Most I've seen will reverse on the
    same "threads" to make it easier.

    I am a recent convert to Avoid-the-potential-negative
    consequences-of-mounting-a-filter-unless-you-can't-avoid-it. I used to
    figure if by default Canon put such a substantial piece of glass in
    front of its 85-300 f 4.5 zoom, there must be something to the idea.
    Lens design seems to have changed, science marches on.

    I march on without my traditional/habitual UV filters (except on the
    70-300 IS; still a little scared...? I might even take the lens out of
    its case, one of these days...

    I never take it off, except to put on a polarizer. I keep hoods on all
    my lenses, actually -- I prefer rubber ones that screw into the filter
    threads (which have the added advantage that you can screw them into
    the polarizer and then turn the polarizer with them). The plastic one
    on the kit lens gets in the way, but with the wide angle, you really
    can't use anything more substantial.

    Aside from the flare blocking, a filter is great lens protection, too,
    without the downsides of a UV filter.

    I too, joined that club, when I saw the negative effects of a Hoya UV filter
    on images from my 20D...

    -- can interfere with the autofocus-assist light (used in low light
    levels to speed autofocus) (at least with the HB-18 hood on the
    28-105mm 1:3.5-4.5 D lens which I use regularly). I did not buy
    the kit, as I already had this lens, which I liked, and I
    prefer the slightly longer focal length to the slightly wider
    end of the lens with the kit. Just as with prime lenses, my two
    favorites were 135mm and 50mm. But this varies with the kind of
    photos which you take.
    While the HB-18 is quite substantial -- and it bayonets on, so I
    can easily reverse it for more compact storage.
    That would be nice -- but yet another thing to break -- and I
    would expect this to be a rather fragile part of the lens.

    Yes I used it with the built in flash, and i got shadowing.

    I had the same experience (at wide angles). You get a crescent shaped
    shadow at the bottom center of the image.

    No, I meant lens cover. I've always used filters to protect my lenses (I
    realize this can cause vignetting in some instances) and if you can put a
    lens shade on top of the filter you have pretty good protection against
    impact from all angles. I even clean the lenses with my shirt, as I'm only
    cleaning the filter and not touching the lens. I've also replaced more than
    one broken filter or bent shade as it saved a lens.
