Is the leica m11 hard to focus?

The Leica M11 is a rangefinder, so you focus manually, through the viewfinder. There's no autofocus to lean on. The site doesn't say how hard that is to learn, so I can't give you a verdict on the difficulty. What I can say is that focusing is the whole point of the camera, and it suits people who enjoy doing it by hand.

If you want to try it, start with a standard lens. The Leica Summicron-M 50mm f/2 is a sensible place to begin. Full specs for the body are on the Leica M11 page, and if you're weighing the screenless or other variants, the Leica M11-D and Leica M11-P pages cover those.
