Originally posted by RockvilleBob Exact issue I had, including the timing issues for turning the power on.
AND
When I called Pentax support they told me to return the camera since it was not working. I returned the Silver edition and received the black K-3 with the grip on back order.
I emailed Pentax support regarding this same problem and have yet to get a reply.
If this problem turns out to be common and fixable via a firmware update, Pentax may rethink this approach to resolving the customers' concerns. Besides there be more bugs as people explore the camera's features in the real world. Fixing every issue by returning the camera could get a bit irritating.
The camera has been trouble-free for me otherwise and my workaround of using one battery will suffice while Pentax sorts out all these initial problem(s).
Please let us know here how the replacement works out!
