Wimberley Quick Release plates are renowned for their quality and important innovative features, which distinguish them from other plates on the market.
Dual Safety Stops
The safety stops at the front & back of the Wimberley P50 plate prohibit your lens from accidentally slipping out of the quick release adapter(easily removed with supplied hex wrench if desired).
The Wimberley double-dovetail design allows attachment of their Shape Shifter flash bracket system to the upper or lower surface of the P50 plate.
Works with All Common Flash Brackets
Drilled holes accept flash arms from Kirk & Really Right Stuff
Lens feet with larger 3/8" mounting holes require insertion of a 3/8" to 1/4" reducer bushing to fasten plates using these holes.
The P50 plate is for use with the following lenses:
Pentax: 250-600mm 5.6 ED(IF), 600mm 4.0 AF SMCP-FA, 800mm 6.7 IF SMCP-67, 1200mm 8.0 MF SMCP-A
Note for Sigma Lenses:
The above recommendations assume that the standard factory foot is installed on the lens. It has come to our attention that Sigma sometimes installs their larger TS-41 Replacement Collar and Foot on their lenses. We suggest that you measure the length of the foot on your lens to make sure that our suggested plate is correct (the plate should be about 1" longer than the foot on your lens).
