Hejnar CFR‑009 Foot Replacement – Arca‑Swiss Compatible Lens Foot for Canon EF 500mm f/4L IS USM
The Hejnar Photo CFR‑009 Foot Replacement is a precision‑machined Arca‑type quick release lens foot designed specifically for the Canon EF 500mm f/4L IS USM lens. Its double‑dovetail profile provides dual clamping surfaces, and the built‑in Quick Detach (QD) socket allows attachment of standard push‑button QD mounts. The QD system—trusted by NASA, law enforcement, and military agencies—helps prevent accidental strap release, especially when the camera is hanging from the shoulder.
Straps compatible with QD mounts are widely available from eBay, Amazon, Cabela’s, Bass Pro, and other outdoor or photography retailers.
