CP-42 Lens Adapter Plate - Canon 400/4 IS DO / 300 2.8 IS Lenses
The CP-42 does not replace the original foot - it is a very low profile "plate" that attaches to the foot. It has a shape specifically designed to hug the curvature of the existing foot thereby keeping it from turning once attached.
Purchase includes a wrench for foot removal plus wrench and stop screws for the plate.
OPTIONAL: Wimberley flash bracket system components are compatible with this adapter plate and available through the NatureScapes.net store. Learn more about Wimberley flash brackets →
