I'm searching for D7000 compatible tripod in local online market. D7000 body doesn't have small whole near the screw as shown below (well it has but pretty far).
However, in the local market whatever I hit has some small element near the main screw.
So can somebody show the plate(s) which are compatible with nikon? What is the standard name for Nikon's plate and what is the standard on plates shown above?
