For some reason, most manufacturers don't seem to realize that tripod plates should be as thin as possible so they don't get in the way.
Peak Design have understood this with their latest Capture Clip plate. However, that plate is poorly suited to mount on a heavy lens' tripod foot.
I have a good number of very solid and large plates, from the likes of Sirui, Vanguard, as well as some chinese copies from eBay (which are just as good as the original, for a fraction of the price).
Sunwayfoto makes the PT-26 which is about 5.5mm thick, a very good value. Again, it's minuscule and not suited for heavy lenses. Sirui makes a small plate for their compact tripods, same problem.
My ideal plate would be about the dimensions of a PU-60 (the pretty standard 6cm long, 3.8cm wide) but about 5mm thick and in a perfect world would have two screw holes.
Does anyone know of something comparable?
