I cannot set an F stop of 4.0 using my EOS 60D with my Canon EF 75-300mm 1:4-5.6 IS lens. I have tried changing the shutter speed and the ISO and I still cannot set an F stop of 4.0. Any recommendations? Thanks in advance.

You would need to contact Canon for repair options and prices. All we know at this point is that it's not correctly reporting it's focal length to the camera -- we don't know why. It should be serviceable.

You would need to tell them that the lens always reports 300mm as the focal length even when set to other focal lengths.

He has tried it on 2 bodies though. If he is sure he tried the lens at 75 both times on both bodies I don't think it is the body.

Why do so many people say "FER-tographer"? Do they take "fertographs"?
