Originally posted by grahame I had a K30 that was very slow on almost everything. It took 2-3 sec even for turning off: the screen kept on after the power switch was turned to off; the light meter system also took 2-3'' to respond to quick light change.
It turned out the mainboard (processor) had issue.
I hope your K3 is not like this.
Doesn't seem to behave like your camera:
I was using only one SD card in slot 1 then I've just inserted the two Sandisk 32GB cards and .... guess what?
The power up seems (I think) faster ! ??
Power down stayed the same ... roughly 1.5 - 2.0 seconds.
Anyway, this is not a big deal and I will go out tomorrow and try to get some wildlife (after the snow storm and freezing rain) to see how this K3 performs related to "high" ISO, i.e.: 1600 and up, outside.
