i dont mean the fastening of the camera.
i mean the fasteningmethod of the legs.
the standard one is with screw clamping the other one is FAST-CLAMP leg lock
but the fastclamp is a bit tricky with the humidity.
for fastening the camera at the tripod i would recommend a good "fast" system it is easier than always rotating the screw
i have this one novoflex q-mount (bombproof)
i also hve only one camera (calumet 400) but it is really very comfortable using a quicklock.
