This plate fits Canon lenses 400 f2.8 IS, 600 f4 IS and 800 f5.6 IS.
Canon long lenses have very tall mounting feet, making them top heavy and difficult to pack. Fortunately, these feet are easily removed. Wimberley offers a special plate that replaces the foot on these lenses and also serves as the Arca-Swiss style quick-release plate for the lens. This adapter plate reduces the weight and bulk of your lens and, more importantly, it lowers the center of gravity of the lens, thus making the lens easier to handle.
The adapter plate is custom designed and has the same dual safety stops found on Wimberley quick-release plates and is milled to accept Wimberley, RRS, and Kirk flash brackets. The plate has 1/4" and 3/8" tapped holes for mounting to other tripod heads or monopods. All tools needed to remove your existing lens foot are included.
The AP-602 lowers the overall height of the lens by about 1.5". Please note that this particular plate mounts so close to the lens that it is difficult to use the plate as a handle.
Includes a 5 year warranty.
