Yes, you need a reversing adapter - one such (may be the only one, my UK
dealer's catalogue claims it's unique) is made by Novoflex and comprises
one adapter that fits on the front of the camera (to which the front of
the lens is screwed) and a second fitted to the back of the lens (which
is now at the ront) to provide the EF connections. The two parts are
cable linked.
In the UK it retails for around £190, so it's probably around $200-250.
