pgk Posted March 17, 2012 Share #41 Â Posted March 17, 2012 Advertisement (gone after registration) All other constants were the sam Were these wide open? They make me suspect that your original comparison photo are showing differences due to mis-focus rather than lens performance? Link to post Share on other sites More sharing options...

IWC Doppel Posted March 17, 2012 Share #42 Â Posted March 17, 2012 I can see clear sharpness differences with some lenses over others, but some just 'look' flat and uninteresting. Â I think flat structure sharpness provides some insight but very little flat perpendicular information exits in most pictures. Perceived image depth and the feeling of insight to the event, that tangible enchanting image look must relate to more than sharpness at a perpendicular. Â Anyone know if Leica test by looking at images from prototypes in parallel with MTF curves etc ? Link to post Share on other sites More sharing options...
lct Posted March 17, 2012 Share #43  Posted March 17, 2012 ...2. Very slight overfocus. Now Steidl becomes sharper... Thank you Skinnfell. Your overfocus shot (Steidl) looks significantly sharper than the one you've used for your comparo (Yangtze) and shows pretty well the kind of result i'd expect from the Summicron asph at f/2.

Lindolfi Posted March 18, 2012 Share #44  Posted March 18, 2012 Although it is obvious that many Leica lenses have a high modulation in the mid spatial frequencies (10, 20 and 40 linepairs per mm), they also show a high resolution, espcially at f/5.6 and f/8. In fact the resolutions I measured with a microscope in the image plane is often more than two to three times the frequency that can be resolved with the sensor of the M9.  In the best designs, it can even be 6.5 times the resolution of the sensor of the M9. So contrast and resolution do not have to be in competition with each other in Leica lens design. See here: click  I think that the solution to the surprise finding of the OP is inaccuracy in focus and lct makes a strong point by putting the two results side by side.
