I did a side by side comparison of the 28 f/2 Ultron against the ZM28 on the M9, which I realize will result in differences compared to the NEX-5N... but... I didn\'t get the impression that the Ultron is designed for edge to edge sharpness. I thought it was rather disappointing for that. The ZM also isn\'t the hottest of the Zeiss lenses in this respect, but it has much better central sharpness than the Ultron until about f/11, by which point diffraction sets in. The Zeiss is also better into the corners sooner than the Ultron, which needs to be stopped down past f/8. Maybe on APS-C it would be better, but then, maybe not. On it\'s own the Ultron is not a disappointing lens and would be a decent reportage lens but it might be a disappointing choice for landscapes. It seems to have a smoother, gentler \'classical\' character compared to the extreme (central) sharpness/contrast of the Zeiss. If you\'re looking for edge to edge sharpness in a rangefinder 28mm lens, it seems the best options on paper are the Leica offerings.
that sounds right on, I just wonder if the ultron might deliver a landscape shot at f/8. Somebody must have one.
