    What is digital slr?

    I ahve looked at the fuji finepix s7000 and the EOS Digital Rebel

    I don't know what the difference is

    Is one film and other flash card or are they both flash card?

    Do I need a film scanner to put on pc?

    What are the benefits of slr? Seems a lot of people say they are best.

    Any help appreciated.

    This is a honest request for help.

    many thanks

  3. As generally used in these groups, a "digital SLR" is a camera body
    that takes the same (mostly) lenses as some particular line of 35mm
    film SLRs, but which records the images digitally.
    Both store the photos to memory cards of some sort.
    Interchangeable lenses is the biggest one. Also, similarity to what
    we're used to working with (many of us came to digital from years of
    working with 35mm film SLRs). Faster response, faster focusing. Much
    lower image noise levels especially at high ISOs (because they use
    physically larger sensors, and sensors optimized for quality giving up
    things like live preview).

    This is a "money plus effort" for "flexibility and quality" tradeoff.
    The DSLR plus lenses is a LOT heavier and more expensive than
    something like the Fuji S7000 or whatever. However, you can do a lot
    more with it if you take the time to learn how and work hard enough to
    actually do it. Which will fit your needs/desires better, you'll have
    to figure out for yourself.
    Hope that helps!

    Many thanks for your imput everyone.

    I understand a bit better now so will be able to do research better than
    what I did origanly.

    Thanks for your time

  8. What is digital slr?

    Here's the basic story.

    There are at least two ways of dividing up cameras.

    1. Digital vs. film. A digital camera captures images to a flash
    card or other electronic medium. Digital is usually better for
    capturing digital images, and certainly more convenient for capturing
    digital images. In fact, for snapshots and medium-quality
    enlargements, digital is more convenient in every regard. But a
    digital camera will be more expensive than a film camera of the same
    quality, sometimes much more expensive.

    2. SLR vs. fixed-lens. An SLR lets you change lenses, while a
    fixed-lens camera does not. (There are other non-SLR cameras that
    also let you change lenses, though.) The reasons an SLR is better
    than a fixed-lens camera are threefold: First, you can change lenses,
    so you have more flexibility. Secondly, because you can use more than
    one lens, you don't have to have one lens that does everything, so you
    get higher quality. Thirdly, most SLRs are designed to be of higher
    quality than most fixed-lens cameras.

    A digital SLR is just that: a digital camera that lets you change

    Nope. An SLR (Single Lens Reflex) has a single lens (as opposed to dual
    lens cameras[1]), and uses a reflex (mirror) to send the image to the
    viewfinder. Whether or not the lens is interchangable has nothing to do
    with it. The fact of the matter is that virtually all SLRs have
    interchangable lenses; however, some rangefinders do, too.

  10. De facto perhaps but not *required* by the words "single-lens reflex"!

    Erm .... while that may often be true, it is far from being on the mark!
    There are plenty of non slr's around with interchangeable lenses - albeit no
    digitals that I know of.

    The reason for the SLR is the desire to see what you are actually framing.

    The Single Lens Reflex allow the user to view the actual image which will
    hit the film plane at the time of exposure through the taking lens.
    Twin lens reflexes used two matching lenses, one to view and one to shoot.
    This was better than optical viewfinder cameras but did not totally
    eliminate parallax error. Nor could you see the effects of graduated filters

    The beauty of the single lens reflex is viewing through the taking lens: you
    can accurately preview depth of field. take real macro photos (virtually
    impossible with any other camera) and experiment with filters before
    exposing a frame.

    The advent of digital means that there is less "risk" attached to taking
    frames since they are virtually free

    exactly the sort of live framing advantages only previously available with
    SLR cameras.

    Up to a point. But a (as yet) there is no camera with an LCD or EVF that is
    capable of resolving detail sufficiently accurately to take macro 'photos or
    to accurately evaluate D.O.F ..... I accept that they are vastly better than
    optical viewfinders. But still (currently) limited in capability.
    Tumbleweed, Mar 18, 2005
  14. Which is precisely why I said "framing", and made no claim that a DSLR
    finder was the same as an EVF or LCD finder. Focus is not so much of an
    issue with macro, though, due to the much larger depth-of-field on the
    smaller sensor P&S.

    How disappointing, though, to see the one manufacturer who had actually
    made progress in that area with an excellent VGA resolution EVF cut the
    cost on their next camera with a much poorer resolution EVF. Perhaps they
    were starting to compete with their new DSLR line....
