Aiming to improve on the default design, the Leofoto SF-02 is a collar foot for the Sony FE 200-600mm f/5.6-6.3 G OSS lens. This is a meticulously engineered aluminum support with built-in Arca-type dovetail mounts featuring 1/4"-20 and 3/8"-16 receivers as well as a QD socket for quickly attaching a compatible strap or sling. Two M3 screws are included for use as optional safety stops.
