Q. Why does my canon 2x lens extender not work?
It is mainly a physical problem of the front element of the extender lens sticking out too far to physically connect with some lenses because their rear element is too far back and it clashes (or crashes) with the extender. Secondly, be aware that a 2x extender will cause a 4x light loss through the optical system (i.e. 2 f-stops slower).
