so, I was noticing a problem with my Z in that sometimes It would kind of lock up. You could fire the shutter and capture an image but the back screen and controls were just dead. No image review, no changing of any parameters. Usually got it back by shutting the camera down for a bit. Sent it back to my dealer who shipped it in to Ricoh Pentax Canada. 6 weeks ago. After a couple of weeks of questioning, they now say it is off to Japan. They were trying to figure if they were going to charge me $100 or $400 for this service. My dealer told them where to go and how far - one of the reasons I like the guy. Also free beer when I occasionally show up at the store(not actually in the store which would be nice sometimes.). My D was looked after fairly quickly a few years ago while Pentax Canada still existed but this new service model just sucks big time. It seems that the new paradigm is money grabbing by any method.
