Lately I've been looking into getting the Canon 35mm f2 lens as my first prime. Now, I have one of the Cinematics lens gears found on Ebay, and from looking at the photos of the lens online it seems as though the lens is really short, with the focus ring about halfway the length of it. With the shape of the T2i body and the protruding flash head, will I be able to put the gear onto the lens and it sit well? I'd hate get it and not be able to have it work with my equipment. Thanks!
