Difficult to quantify I know but how much difference in image resolution and sharpness would you expect to see when moving from a high quality 35mm slr system to a high quality rangefinder system. I'm thinking specifically of comparing contax/zeiss to zeiss ikon/zeiss image quality. Perhaps in terms of how much extra enlargement you could get out of the rangefinder before noticeable degradation of image quality compared to the slr. I fully realise there are many other factors to consider about the differences and use of the two systems and what they are best at doing, but for this specific question assume expansive landscape images and cameras on tripods. Will the rangefinder give noticeably better quality images at say 12 times enlargement.
