I keep hearing crop body but haven't a clue what it is. What's a crop body?

    A "Full-Frame" (FF) 35mm format camera, whether film or digital, has a frame size of 36mm x 24mm.

    A "crop" format camera has a smaller imaging area, just as though you would "crop" a portion of a FF imager. The name comes partially from the "crop factor" that you apply to better understand how different focal length lenses are affected when mounted on a crop camera versus a FF camera body.

    Typical crop formats are:
    • 1.3x - Canon 1D series cameras, also called APS-H digital format.
    • 1.5x - Nikon DX, Pentax, Sony, ..., also called APS-C format.
    • 1.6x - Canon dRebel and Canon xxD cameras, also called APS-C format.
    • 1.7x - Foveon/Sigma SDx and SDxx series cameras.
    • 2.0x - Olympus and Panasonic "Four-Thirds" and "Micro Four-Thirds".

    I would rather talk about what lenses are "standard" focal lengths for each format (approximately):

    For FF cameras, a 50mm lens is often quoted as a standard focal length (since it is close to the measure of the diagonal dimension of a FF frame). This also approximates a human Field-Of-View (FOV). (45mm through 55mm lenses are also considered standard lenses for a FF camera.)

    For 1.5x and 1.6x crop cameras, 35mm is often called a standard focal length.

    Just divide 50mm by the crop factor for other crop format systems to estimate the standard focal length for that system.

    Thank you. I was thinking it might be a full frame camera, with a lot of pixel's and it allow's for more crop. My D70 and D5000 must both be "crop" cameras. I sure can crop my D5000 photo's more than my D70.

    As was explained, it has nothing to do with pixel density. It's simply a description of the sensor or film dimensions.
