Originally posted by JeffJS Probably close to the amount of replacing the camera. I would be willing to wager that the sensor and the IS are all one mechanism, if this in fact is a Mechanical problem, and would probably have to be replaced as such. It is also possible that the circuit driving the IS has gone south. The only way you'll find out for sure is to send it in for a service estimate. You could probably write Pentax service and ask for a worse case estimate.
Yeah, the SR is sensor based, right? So my guess would be too that it will be the whole sensor-unit repaired. And replacing it will cost easily more than a new camera.
I just send an email to the service, so we'll see what they say.
And I took a short videos to demonstrate the problem to the insurance company and to the Pentax community. I'll post a link to it here when I manage to put it to Vimeo or to some other videohosting service.
The whole mess is still somehow f****n hilarious: sounds like there's a crappy old two-strike engine inside the camera... Potpotpotpotpotpotpotpot... poootpotpotpotpot...
