Originally posted by Adam First of all, are you using a UHS-I memory card? Second, AFAIK the correct way to wake the camera is to half press the shutter. Doing so and then pressing other buttons may thus yield a faster response. Third, maybe increase the delay before the camera goes to sleep so that this doesn't interrupt your photo viewing?
^^^ This for sure. I have tried on my K-1 and the Play button adds additional time as it loads some images to view. Half push of shutter is faster. I also have a longer sleep time set.
