Just a short note to tell you about a new way I've found for attaching the Leica S to the tripod's head.
It's via the Novoflex L-Bracket. With it it's possible to go quickly from horizontal to vertical without changing the tripod's head position, something every L-Bracket should allow.
This Novoflex part has an Arca-Swiss profile, and fits seamlessly in the Castel-Q rail. Together they form a quite small and light panorama rig, for rotating around the nodal point.
Besides, this L-Bracket gives a good grip for the left hand.
And with it the camera can rest, both horizontally and vertically, on a flat surface without the danger of scratching it...
