Hejnar CFR‑007 Foot Replacement – Arca‑Swiss Compatible Lens Foot for Canon RF 800mm F11

The Hejnar Photo CFR‑007 Foot Replacement is a precision‑machined Arca‑type quick release lens foot designed specifically for the Canon RF 800mm F11 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.

Attach your preferred strap to a QD‑compatible clamp, then mount the clamp to any Arca‑type plate, L‑bracket, or foot replacement. QD‑compatible straps are widely available from eBay, Amazon, Cabela’s, Bass Pro, and other outdoor or photography retailers.

✅ Compatible With

Arca‑Swiss style clamps
Markins, RRS, Kirk, Wimberley, Acratech
Photo Clam, Foba, Jobu Designs, Custom Brackets
