What's the typical size of a RAW file out of a 10D? - Photography

What's the typical file size (or expected range of file sizes) of a full resolution RAW image out of a 10D. Just trying to get the right CF card in ahead of camera delivery! TIA -- Alan F Cross...

    What's the typical file size (or expected range of file sizes) of a full
    resolution RAW image out of a 10D.

    Just trying to get the right CF card in ahead of camera delivery!

    TIA

    I get 80 with a 512MB card (smallest embedded JPG).

    From the same camera? This does not compute, by definition RAW is the actual
    sensor array information and will be the same size every time.

    Shouldn't matter, RAW is RAW.

    The only reason the Canon 10D RAW files vary from 6 - 8 Mb is that there's a
    second file, a jpeg, attached. Otherwise they would all be the same size
    regardless of what you shot. Are you saying your Canon 10D RAW files vary from
    4.3 Mb to 13.86 Mb, or were these file sizes from two different Canon cameras?

    Bill,

    Canon raw files are compressed -- although lossless. The DO vary in size.

    Sorry John, I was totally wrong about RAW being uncompressed. After reading
    Don Coon's post I checked the actual size of some of our RAW files and found as
    much as 20% differential in file sizes, which I never really noticed before.
    Obviously I never shot in the extremes you did or I'd have perhaps noticed.

    You were right, I was wrong, sorry for my erroneous post. I eat those words!

    You're right Don, sorry. The files we have were much closer together in size
    that what John Sheehy posted so I assumed the numbers in the Canon manual were
    gospel, but looking closely at the file sizes I see around 20% delta even in
    roughly the same light. My mistake, John was right.

    Yup, Canon 10D. JPG set to smallest embedded. Actually, this number
    will change if you change film speeds. My default is ASA 100. A
    higher speed will bump the number down.

    Same camera. 10D.

    As I understand it (maybe I dreamt this), the RAW data is separated into
    bitplanes and run-length encoded, so when the values are highly
    redundant, they compress well, and when they are not redundant at all,
    the encoding is an inefficient waste of filespace.

    Yes, but I don't think RAW is a simple matrix.

    Same camera.

    Never believe what you read, if you can test for yourself.
