New Canon replacement foot for the EF 500mm f/4L IS II USM and EF 600mm f/4L IS II USM. Will fit all IS II lens as well as a few older models.
New and adjustable lens foot for the New Canon is II line of lenses. Plate will adjust for tele converters and larger camera bodies. Due to the new light weight and design of the new line of canon lenses a new type of plate had to be designed. We made this with functionality in mind. You now will be able to choose where your plate lines up. You will have 6 set positions that you can move the mounting surface back and forth to accommodate tele converters and larger camera bodies, without pinching your fingers or not being able to find your balance point.
