Aiming to improve on the default design, the Leofoto SF-01 is a replacement for the original foot supplied with the Sony FE 70-200mm f/2.8 GM OSS and FE 100-400mm f/4.5-5.6 GM OSS lenses. The SF-01 replaces SONY's original lens collar foot and provides a lower profile and a lower center of gravity for a better balance.
Compatibility:
Sony FE 70-200mm F/2.8 GM OSS I&II FE 100-400mm F/4.5-5.6 GM OSS
Sony FE 300mm f/2.8 GM OSS Lens
