Allain Very good! But there is no data about film or development. Also about lenses used in comparison. Leica pictures are more saturated and in general slightly greater. If it were used Summicron versus Helios44, it would have happened the reverse once the 58mm is greater than 50mm. Normally there are no differences in this picture size and with internet resolution, but in my opinion Leica pictures used a polarization filter. Without any technical data it is difficult to judge Let's Bill be the judge with his large experience. Regards Luiz
It is interesting, it also seems like Leicaflex had a longer lens than Zenit.. also as I understand Leicaflex was never a successful camera in comparison to its rangefinder counterpart, it would be more interesting to see one of the FEDs compared to a Leica rangerfinder... like maybe FED 5 with I-61L/D vs. a Leica M6..
