After several years of heavy use, the time has come for some servicing on one of my M6 bodies. To wit: 1) the frame counter is sticking: it does not advance past 32 frames and usually fails to reset; and 2) the lens preview lever works only when a lens is attached to the body. Repairs are, of course, available by Leica. This, however, involves sending the camera out of the country (New Jersey, USA) with the attendant wait and worry. So...my question is, are there alternatives (Leica approved) available here in Canada?
