The AP-640 Replacement Foot for Sony FE 400-800mm f/6.3-8 G OSS Lens from Wimberley functions as an Arca-type compatible quick release plate for the lens. This accessory adds stiffness over the factory tripod mounting foot when connected to a lens plate to reduce flex and vibration. Designed to produce more secure mounting, this accessory creates more ideal geometry for using the lens with a Wimberley Sidemount Head and Sidekick to allow for the lens to balance optimally. The AP-640 provides a QD socket for sling mounting. Constructed with anodized aluminum and stainless steel, the AP-640 securely holds the lens. The AP-640 includes four 8mm M3 mounting screws, two 6mm safety stop screws, and a 2.5mm T-handle hex key.

Great Replacement Foot on Sony Lens

ARCA and longer with a Quick Connect Socket. Easier to carry the lens with this and much faster and lighter to put it on the monopod and tripod.
The Foot That Sony SHOULD Make!

This is my second Wimberley foot (I own the AP-620 for the Sony 300mm F2.8). The 400-800mm lens is a beast of a lens, and the size of the AP-640 provides much more support for tabletop placement, and it is a much easier to handle grip when carrying the lens. The arca-swiss grooves are how a foot should be designed.
