Hi Klaus,
If those bad corners are symmetrical, and those lenses have better results on other cameras, I guess it must be a sensor issue.
I stil lthink in-body IS is not a good thing, despite many people seeming to clamor for it: position of the sensor is even more critical than positioning of a few lens elements, and much harder to control <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />.
Kind regards, Wim
