You already know the bad news, because if I had to go to Pentax Canada something was wrong with my K-5.
The front e-dial was missing beats, and I had tried all the suggestions posted at . It would click once or twice properly, then need 10 clicks to change again, then bounced back to beginning setting.
Returned my K-5 to Broadway Camera on October 28th. Back from Pentax Canada on November 14. Two weeks! The e-dial works fine, and checked firmware, etc., and then the surprise!
My K-5 was from the period of those with sensor problems, but I have been checking about every 2 months to make sure it was okay, and with no problems.
However, when they serviced my camera, they replaced the sensor, just so there wouldn't be a problem down the road. Not exactly happy that I had the e-dial problem, but greatly impressed with the speed and service.
Now for more shooting - love the camera.
