The Follow Focus Shifter works great with the inexpensive Canon EOS 50mm f1.8 lens, affectionately known as the "Nifty Fifty". Most Follow Focus devices will not work with the narrow, angled focus ring at the front edge of the ring, but the FocusShifter is designed to attach nicely. Whether you're using it on the Canon 5D, 7D, T4i, T3i, T2i, it will work perfectly.
Look about half way down the page to find Instructions for how to setup the Follow FocusShifter on the Canon 50mm f1.8.
