The K-5II exposed the pictures very often (especially proximity) on the extent that the results were simply unusable. Whether directly or indirectly flashed: Manual corrections in the range -1.7; not uncommon!
On a permanent correction setting in the flash unit was not to think: once the picture is correctly exposed without correction; Camera 5 ° horizontally pivoted slightly; re-recording and the camera makes mischief. - Total worse than the Kx previously used. - Annoying!
To make it short: The K-3 (new RGB sensor) are completely alien to such problems. Very good choice of parameters; excellent flash metering. I am very satisfied.
Image quality and autofocus are after the first assessment also noticeably better and internalized the slightly modified operating concept after a short time.
