I note they say, "So far the sensor shift is disabled in movie mode in order not to record mechanical noise."
So presumably the capability has simply been turned off, so should be simple to flick the firmware bit to turn it back on. It leads to the question though as to why they did this and not keep it as a menu option with a warning that it might record mechanical noise, I can accept it might with a built in mic but that doesn't always matter. Hopefully it can be re-instated pretty pronto. And if Pentax read this, don't forget the K-3 variants too (please!)

Some defected purely because they wanted full frame, now sorted!

They've certainly come out well but can I suggest something to give the items a sense of scale?

Yes, it's fascinating to hear the tales of woe since defecting.

Seems Pentax must have read my comment as they hadn't bothered up to now to even mention it! It seems they've indirectly contributed to this thread. Well let's hope.

Err, no! When did Kodak cease trading then?

Should you research it you will find that in September 2013 "the company emerged from bankruptcy having shed its large legacy liabilities." (Wikipedia.)

Obviously, I said as much several posts back. Thanks! Anyhow its OK to be wise after the event.
It is however enabled by default so a casual test of Pentax video by a prospective purchaser at SRS or Jessops or somewhere will highlight the weakness of it when that wasn't the case with the K-5. The OOC video by default looks worse than that from the budget video cameras sold a decade ago for £30 from supermarkets. It's not what you'd expect from a high end camera. They'd be better off without it, only as I said, the marketing bods would not like that.

I'm inferring It would seem that for someone who uses a Pentax for regular mixed dual still/video use the K-5 will still be the best option until the issues raised above are dealt with. I'm not saying the K-5 is the best still camera although given its great high ISO performance there are some who will say it is, not without good reason.
It's regrettable the K-1 wasn't endowed with the K-5 type video system as a minimum as it is the camera's weak link. It would seem it might be better if the software shake reduction system was abandoned altogether given it reduces quality rather than improves it! No doubt that wouldn't go down to well with the marketing guys however.
Having used the K-5 video with success in the past I hadn't realised the present incarnation had become so poor. Pentax need to at least put it back to what it was in the K-5 !

One thing with this, Ricoh must have considered that sales of the K-1 must have been sufficient to make it worth pursuing investment in FF or they wouldn't be doing this. This is after the previous brand owners have said for twenty years no one would want a full frame camera!
I must say this new 50mm lens looks huge so suspect they're going for ultimate resolution with this as the more compact film FA's etc are plentiful. No real point in re-inventing the wheel!
Given a few years I suspect things will circle round as they always do and they'll release an MX/ME FF digital with a range of new M style lenses for it. It'll be a way of boosting further sales. They've just done that with APS-C with release of the KP. FF will surely follow suit?

Not personally but there's a review page at PF here.
