I understand pretty well your questioning Boris and this is just a little information which may help you understand why your way of shooting/post processing has not changed from K10 to K7 (as for DR etc.):

This shows one thing, as for DR/Iso response, both K10/K7 are extremely similar. K5 is a totally kettle of fish though. Will it help you or not, I can't answer for you of course. -- Thibault Massart aka Thibouille/Thibs ---------------------- Photo: K-7, Sigma 28/1.8 macro, FA50/1.4, DA40Ltd, K30/2.8, DA16-45, DA50-135, DA50-200, 360FGZ ...
