Yes, and both without on-board flash *evil grin*

The K-3 II is a sign of things to come so I'd be shocked at this point if the full frame camera omits GPS in favor of a flash...but that means it could very well get 4.5 stops of IBIS, Pixel Shift Resolution and all the great features in the K-3 II that are new...

Would you like a 60-Mpix sensor in your full frame Pentax camera?

too bad there isn't more resolution, otherwise we could see the cam.

According to my calculations, once a full-frame sensor has passed 37MP, its cells are smaller than those of the K-50; once a full-frame sensor has passed 54MP, its cell are smaller than those of the K-3. At what point do we lose the improved color depth benefits that are supposed to be a hallmark of full-frame cameras?

Right about the point PixelShift kicks in? <ducks>

Regarding that 4.5 stop IBIS, I too am hoping it will be so for the FF, but the thing is, the FF sensor is larger and hence has more mass than the APS-C sensor in the K-3II, thus I wouldn't be surprised if 4.5 stops can't be obtained.

Or, the FF might have a higher-performing IBIS unit than the one in the K-3II, but I don't know if that's getting to be a bit of wishful thinking....

FF has about a stop advantage on the camera shake front being a bigger format. 50mm is no longer a portrait distance. So you get that for free, without any additional tech.

If I understand you right, focal lengths need not be multiplied by 1.5 in a FF, thus an overall gain in effectiveness of stabilisation?

But if i want an equal size image with 50mm on FF compared with 50mm (75mm equiv) in APS-C, I would have to step up closer to the subject, right? Wouldn't this neutralise the gain?

Then, to get comparable DOF as in APS-C I'd have to stop down a bit more, wouldn't I? So that would actually introduce loss...?

So roughly speaking, comes to about the same?
You don't buy FF to get the same results as with aps-c.

Sorry, I edited my post while you replied, so your quote now differs slightly compared to my (edited) post.

In any case, I understood your point of view; thanks for the response.

Reflecting further, if FF has a stabilisation advantage over APS-C, where does this advantage stem from, if I might ask? Was thinking it through but don't quite get it...

For example if as a portrait photographer I use an APS-C body @50mm focal length, effectively the IBIS has to stabilise a 75mm focal length, after multiplying 50 by 1.5.

But if instead I chose to work with a FF body, as many portrait photographers do, I would then chose a lens of approx 70-85mm focal length, say, eg. the FA77. Thus the IBIS now has to deal with a true 77mm focal length (this time without having to multiply by 1.5). So it's working out to the same thing, it seems to me. I'm sorry, I don't understand where the stabilisation advantage is coming from.
