The Kirk LP-28 Lens Plate is designed to take the place of the original tripod collar foot of Canon 300mm f/2.8 IS & 400mm f/4 DO IS lenses. It converts the collar to make it directly compatible with Arca-type quick release clamps, without the need for additional quick release plates. Critical mass is also reduced.
Each plate comes complete with all the necessary hardware and tools to make the conversion.
