Why not to produce body-specific camera plates?
It would greatly increase the repeatability of camera positioning and approached NN5+RD(x) setups to the templatability.
Nikon D200 and D300 which I used with NN stuff require minor modifications of current camera plate design - enlarge it a little and add a pin! It would increase the production cost on a couple of bucks, which I (and many customers) would gladly pay.
What do you think?
