A."60 seconds at base ISO. The main goal is image quality, and Leica is unwilling to sacrifice quality for longer exposure time. For most applications, 60 seconds should be plenty. In cases of astrophotography, exposure stacking would be a better option, anyway."
Well if correct, that sucks. It could cost Leica a lot of sales for Nature photographers (I know not their market for an M, but it was for the R) or cause us to carry as mentioned a 2nd camera body for such long exposure. As I mentioned to Justin Stailey, Leica seems to have designed the camera in the vain of Oskar Barnack as a fast operating, light hand holdable camera. Usage of the camera on a tripod is secondary and the usage of R lenses as the R solution is/was an after thought. So those such as myself, with such an extensive collection of R lenses, will have to give this much thought.
