Engineered for precision and performance, the Leofoto SF-04 Lens Foot is a premium, purpose-built replacement for the original Sony FE 400-800mm f/6.3-8 G OSS lens collar foot. Designed to enhance stability, usability, and compatibility with modern support systems, this Arca-Swiss compatible lens foot is an ideal upgrade for serious wildlife, sports, and aviation photographers.
The SF-04 is CNC-machined from a single block of 6061-T6 aircraft-grade aluminum, delivering an exceptional strength-to-weight ratio while minimizing flex and vibration. This rugged build ensures maximum durability without adding unnecessary bulk—just 125g—making it ideal for field use.
Ditch the extra plates—this foot features a built-in 38mm Arca-Swiss standard dovetail for seamless integration with tripods, monopods, and gimbal heads. The dovetail design lowers the overall profile and weight of your setup while increasing stability for long-range shooting.
The top surface features a textured silicone grip insert, providing enhanced comfort and a non-slip surface for handheld lens carry. The ergonomic design also makes it easier to grip the lens safely when mounting or transporting.
The base includes 3/8”-16 and 1/4”-20 threaded holes, giving you flexibility to attach accessories or mount directly to non-Arca platforms. It also comes equipped with two M3 safety stop screws to prevent accidental sliding when used on compatible heads.
Integrated into the base is a Quick Detach (QD) socket, allowing you to rapidly attach or detach a compatible shoulder or sling strap, improving mobility and reducing setup time in the field.
This replacement foot is custom-designed specifically for the Sony FE 400-800mm f/6.3-8 G OSS lens. The precision fit ensures optimal balance when mounted on a support system, improving gimbal performance and minimizing strain on the collar mount.
