Comments about Bogen Imaging Bogen - Manfrotto Sliding Plate for 3273, 3147, 3274, 3421, 516:
I own (3) of these units along with a Bogen 3421 / Manfrotto 393 Gimbal Head for high speed action photography. The plates are very well built and a very good value when compared to other brands of plates used with other Gimbal Heads. I have had a slight bit of slippage in the rubber / cork pads, but it is easy to fix with a bit of added glue. The slippage does not occur where the plate comes in contact with the lens mount. The plates are very stable once secured to the lens collar and locked into the quick mount assembly.
