    Does anyone know how third party (Sigma, Tokina, Tamron) Lenses react with the
    Digital Rebel? I know the 10D has some issues with them. Thanks in advance!

    Get the best lens you can afford.

    Fact is, the sensors in these cameras have about 1/3 of the area
    of a 35 mm frame. So the lens really is quite critical, even more so
    than with 35 mm.

    Actually, slightly less than 2/3 of the area of the 35mm frame.

    From the Canon 10D owners manual: image size 22.7 mm x 15.1 mm

    That's 342.77 square mm.

    For 35 mm: 24 mm x 36 mm = 864 square mm.

    343 / 864 = 0.397

    Are you reading the actual size or the usable size?

    In the 10D specs, it is simply labeled "image size."

    On dpreview.com, it is also listed as the sensor size:

    "22.7 x 15.1 mm CMOS sensor"

    Now, is that for the 3072*2048 standard file output, or for the real RAW
    3084*2056 output?
