    Default point of view on a crop factor

    Correct me if i'm wrong, the crop factor is actually how wide the angle of view is right ? and is not actually a "zoom" factor.

    So y do ppl keep saying things like, a 50mm on a 1.6 crop factor is actually a 80mm lens, when in actual fact, what u see is not 80mm !??!

    crop factor is

    if you take a picture using a 50mm lens on a film SLR and then make a print of the full negative.
    then you cut off the four sides.

    the resulting cropped image is your crop factor

    ..... actually what you see is actually 80mm... why not?

    If you don't move your butt, what you see is what you see already. Doesn't matter what lens you use. how much you can capture depends on your lens.

    a 50mm on a 1.6 crop is equivalent to a 80mm on full frame. If you want to include DOF, then a 50mm f2 (1.6 crop) is identical to 80mm f3.2 on full frame.

    I think the shop uncle is right but many people here are misled by CS
