    so the rebel 300D 350D 400D are all 1.6
    the 10 20 30 40D are 1.3
    and the 1d is full

    :confused: is that how it works...

    then to figure out the 35mm equivalent say with a 50mm lens on a rebel, the 1.6 crop is 50*1.6=80mm

    :dunno::confused:

    incorrect. everything MINUS the 1D and 1Ds series are 1.6x

    1D is 1.3x

    1Ds is full frame.

    EDIT: i forgot. 5D is full frame.

    10-40D are 1.6x magnification. That means that when you use a 50mm on the body, it is magnified to give you the field of view of an 80mm. Image quality wise it is just as good as using a FF body with 80mm lens.

    have you ever shot with a 35mm SLR camera? if not, the crop factor isn't anything to worry about. Since I never knew what a 50mm shot looked like from a 35mm camera, reading the "35mm equivalent" means nothing to me.

    Exactly. You multiply the crop factor of your camera by the focal length of the 35mm lens.

    Just remember - there are some lenses out there made for digital cameras that are what they they say they are...i.e., you don't take the crop factor into account.

    know what you're talking about before you give people bad info.... yes you do take the crop factor into account.... crop factor has to do with the size of the sensor in the camera, nothing to do with the lenses. The lenses that are "made" for digital camera's (i.e canons EF-S) is the mount.. it has nothing to do with the crop sensor.

    Perfect example.

    Canon EF 24-70 f/2.8L. It replaced the older 28-70 f/2.8L which had been around since 1993...Well before digital was mainstream. On a film body, that focal length range of 24-70mm would provide a certain field of view.

    Now look at the EF-s 17-55 f/2.8 IS. The lens physically has a shorter focal length than the 24-70 but when you put it on a 1.6x crop body youll end up with the same field of view as a 24-70 on a full frame body.

    Make sense?
