Wimberley AP-610 Replacement Foot for Sony FE 100-400mm f/4.5 – 5.6 GM OSS

Designed for the Sony FE 100-400mm f/4.5-5.6 GM OSS lens, the AP-610 Quick Release Replacement Foot from Wimberley is an anodized 6061 aluminum foot that is compatible with most Arca-type clamps and heads on the market. By replacing the original factory foot, the AP-610 adds rigidness and stability and reduces flex and vibration while mounted to a head.

Additionally, a double dovetail allows accessories to attach to the bottom or the top of the foot. The lower profile of the plate provides better balance when mounted on a head as well.

If you’re going to use the optional safety stop screws, Wimberley recommends using a clamp with channels that allow the screws on the foot to slide back-and-forth.
