CP 51a: Replacement Foot for Canon 500 mm. f4.0 Telephoto Lens
A highly sculptured full replacement foot; just long enough to cover the balance point, just tall enough to fit under the lens hood. Has a double cut dovetail to accommodate flash arms using the ARCA style mount, and a 1/4 mount to accept mono pods. Improved balance for ball heads and action heads because of a 2.7 in. offset from the lens center. Featuring our unique "Limit System" providing an improved anti drop function. ARCA compatible like all 4th Generation Designs products. Wrench and limit screws provided.
