This was amended with the introduction of the M2 (1957) and in addition the 35mm Summaron was produced with eyes for the M3 & the cam ground to bring in the proper frame-line on the M2 & later Ms. Mary G. ===================================================== In a message draken@pacific.net.sg writes: > Dear all, > Hi.
