    somebody explain to me how the lens focal length conversion factor works. for example, the canon 1d has a 1.3x conversion factor. what happens to lenses like 28-80 or a 300mm lens?

    1.3x conversion will make a 28-80 a 36.4-104

    and a 300 equivalent to a 390....

    But, with a DSLR add a couple mms to the focal length... since the sensor is not full frame unless you have the 1DS...

    the other full frame sensor is the kodak 14n, which has been riddled w/ problems since it was first released and is still only available in limited quanties

    to help clear up the multiplication factor, its not really multipling, its technicly cropping of the photo

    i can tell u though that the 16mm fisheye i have on my 10d barely has any "fisheye-ness" to it at all
