Originally posted by rvannatta While I haven't been losing sleep over FF, I have been a bit nervous about Richoh's intentions. But committment to the to some higher end stuff is the word I have
beenhoping for. I've spent close to $10,000 in Pentax stuff in the last year, and if their future is the Q line, I've made a very dumb choice of purchases. The KAF mount seems to inclulde a protocol that allows the camera body to determine what lens is mounted. This appears to be the case with all lenses that are Auto focus, but not the case with the A series or older which is why the A series requires manual input as to the focal length.
All of this would make it very feasible and possible to make a high end camera body that worked with all pentax glass. Since there is no APS-C glass that doesn't identify itself as such, a high end body that defaulted to FF, but which recognized 'cropped' glass and cropped accordingly could work with all pentax glass. Given the megapixel count of the likely next sensor, there will be plenty of sensor power for the project.
This is exactly how the Nikon FF bodies work (maybe Canon too, I don't know.) It is a mildly useful feature. An aps-c 'frame' gets superimposed over the image, making composition easier.
You also have the option of turning that feature off and just shooting the DX (aps-c) lens in FX (FF) mode, and cropping of the edges later yourself in post. The reason you may want to do that is because some of the aps-c lenses will cover the FF sensor, with increasing vignetting as distance to subject increases. In Pentax's case, there would be fewer lenses you'd even need to shoot in 'crop' mode, as even some of the DA's actually work on film (DA 40, DA 70, DA* 55, DA* 200 & 300, others.)
I'd expect Pentax to offer that feature. On my D700, I'm left with about 5-6MP on the target after auto-crop - If a Pentax FF had a 24mp sensor, it would be around 10-11MP on the target. You wouldn't buy it just to shoot cropped, but it would make a very fine 'aps-c' camera if needed, and work with all your Pentax lenses.
