There is no error message. It is a new 700d camera, but the lens is a few years old, and hasn`t been used for some time.
Thank you; I have done that, but image-stabilisation still does not work.
It is a new camera, and the lens has not been used previously on this camera; I have tried it on a 5D, and it doesn`t work on that either.
I have solved the problem; There was nothing wrong with the lens.
The lens has tbe active for IS to work, which I had forgotten !
