The low profile of this replacement foot provides a lower center of gravity for better balance when compared to the original foot of the telephoto lens. The plate has 1/4"-20 and 3/8"-16 mounting sockets in case there is no mounting clamp present, and an integrated QD socket is compatible with QD adapters, straps, and slings. Optional safety stop screws are available with the foot to prevent the foot from sliding out if a quick release clamp is accidentally opened.

Really Right Stuff LCF-103 Reviews

Fit like a glove

Fit like a glove, lightweight and arca swiss.

This foot profile is too high

By Shaul
Rated 2 out of 5
Date: 2022-11-03

The construction is good, but the foot high profile will not let you fit the enormous hood over the back of the lens in a back pack(Backlight 40L). Also unnecessarily exensive.

The Really Right Stuff Lens Foot for Sony FE 400mm f/2.8 GM OSS & FE 600mm f/4 GM OSS Lenses will not fit for the 300mm lens. Instead, RRS recommends the Really Right Stuff LCF-101 Replacement Foot for Sony FE 100-400mm f/4.5-5.6 GM OSS and FE 70-200mm f/2.8 GM OSS Lenses (B&H # RELCF101RF).
