Leofoto SF-04 Arca Lens Foot for Sony FE 400-800mm f/6.3-8 G OSS

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.

Precision-Machined for Performance

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.

Arca-Swiss Compatible with Built-in Dovetail

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.

Comfortable and Ergonomic

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.

Threaded Mounting Options

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.

QD Socket for Rapid Strap Attachment

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.

Optimized for Sony FE 400-800mm G OSS

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.
