This is a cross post from the other similar thread, but figured people reading one or the other would want to be aware....
Add another to the list.
Intrigued by pixel shift and the recent
Adorama price drop, I went for the K3 II as a second body to carry for landscape shots on vacation this summer (original K3 will remain with the telephoto). Inserted a charged battery, input time & date and formatted cards only to realize it wouldn't turn off. Having read this thread, I hit the GPS button and sure enough, the camera froze.
It may just be me, but the back wheel also has a much cheaper tactile feel (when rotating) than my K3.
Now for the joy of repackaging, returning, waiting and hoping the next one works properly.
