    Is EF lens mount the same thing as EF-S lens mount.

    Great question!

    No, EF and EF-S lenses are different. EF-S lenses are a subset of Canon lenses created specifically for APS-C (cropped sensor) cameras, and are not compatible with all Canon cameras. EF-S lenses have a white, square alignment marking while EF lenses have a red, circular alignment marking.

    Thankfully, both EF and EF-S lenses are compatible with most Canon APS-C cameras. However, EF-S lenses are not compatible with Canon’s full frame cameras.

    Before buying any lens for your camera, make sure it’s actually compatible!

    This question is covered in the Foundations Course Lesson 1.4, Factors to Look For in a Lens.

    Just to clarify a little. 🙂

    You CAN use an EF lens on EF-S (a crop-sensor APS-C camera), but you CAN’T use an EF-S on a full frame EF mount camera.

    That’s nice, because you can invest in expensive, good glass that is still compatible with your cheaper camera, then when you upgrade to a full frame camera, you still get to use your good glass with your good camera!

    I am planing on up gradeing my camera,and the one I am looking at uses a EF mount and I have EF-S mount lenses. Do I have to git EF mount lenses?

    I would really like to upgrade my camera. I am looking at the 80D Canon, but I do not know if that is too much camera for me. (I am up grading from a canon Xti)

    The 80D is still a crop camera and uses ef-s mount, so your ef-s lenses will work on it! (as mentioned, any EF mount lens will work on it too.)

    Don’t have it myself, but it appears to be an awesome camera, a good step forward from its predecessor.

    Wow, that’ll be a grand upgrade! Have you purchased it yet @missyruth?
