Aiming to improve on the default design, the Leofoto CF-01 is a replacement for the original foot supplied with the Canon EF 200-400mm f/4L IS USM Extender 1.4x , EF 300mm f/2.8L IS II USM, EF 400mmf/4 DO IS II USM, and EF 500mm f/4L IS II USM lenses. This aluminum support with built-in Arca-type dovetail mounts features both a 1/4"-20 and 3/8"-16 receivers as well as a QD (Quick Disconnect) socket for quickly attaching a compatible strap or sling. Two M3 screws are included for use as optional safety stops.
