Markus, unfortunately not. MP2/100ZE optimum aperture is f/4 (it\'s as sharp and has similar contrast at f/2.8, but f/4 will improve vignetting and bokeh quality, while closing to f/5.6 doesn\'t improve the image) and while you focus S3.5/100C/Y with live view 10x mode you see how it gets sharper when closing to f/4 and then to f/5.6, but not anymore to f/8. Also due to vignetting C/Y bokeh gets worse on corners if both lenses closed down to f/3.5.
Thanks again! Both lenses are relatively new lenses in my bag and I haven\'t tested them thoroughly nor compared to other lenses yet. From my shots I got the impression that the Sonnar is already very sharp wide open (as is the ZE). Good to know where their optimum is, makes me use both lenses better
