    Canon Leses?

    Hello I was wondering if there was like a basic introduction to canon lenses... That includes such things as what the MM stuff means, what EF -S and this sort of stuff means also does a full range zoom lens make up for wide angle and telezoom? Thanks so much!

    "MM" is millimeters and is the measure of the focal length. Bigger the number is more magnification. EF-S is a particular type of Canon mount.
    The "F" number of a lens is related to how large an aperture the lens has. Smaller number is better as it allows more light in.
