yes, the M 2 would be a good choice. In my opinion this model has the most clearly arranged view-finder with only 3 frames for 35, 50 and 90 mm. For 135 mm the magnification of 0.72 the M 2 was not considered to be sufficient by Leitz. When this camera appeared on the market it was called the "Weitwinkel-Leica" (wide-angle Leica). Many users had asked for a 35 mm frame.
