[Leica] carry camera - eco pancake

[henningw at archiphoto.com (Henning Wulff)]

The problem with Robot lenses is that they weigh a ton. Everything in 
the Robot lineup weighs a lot more than I'm willing to carry and they 
don't suit the lightweight G series.

The mount is actually an interrupted thread bayonet, and is probably 
the most secure and solid lensmount ever made. Also, since the basic 
design is for a 24x24 camera, and only later did they add a 24x36, 
the diameter of the mount is rather small, and the lenses are 
therefore generally slow although a couple were f/2 and f/1.9.
