New Pentax FF ..image released on PhotoRumors?
K-5, K-x, DA* 50-135, DA 70 Ltd, FA50 f1.4, A50 f1.7, Tamron 17-50 & 90 f2.8 Di macro, Sigma 17-50 f2.8 & 10-20, Metz 58 & 48 AF-1
There's nothing yet to suggest from the image that this will be anything apart from a traditional Pentax - styled DSLR, continuing the styling and feature developments on from the K3 /645z models. We'd expect slightly bigger than K3. So not a mirrorless or retro style (I'm glad!).
I assume the crop-mode would require a viewfinder magnification adjustment? Is that all that would be needed, a control to switch the magnification for the different lens image circles ... Is that a practical thing ? I assume it would have to be a manual user operated switch ....
Exciting times (and expensive ones? ) ahead! Now, I'd better get my microscope out and start looking at those images from my FF lenses carefully!

I've tried a couple of non Pentax FF, and was slightly underwhelmed by the increase in viewfinder size. I hope this Pentax will be different with a good image magnification, and a big bright viewfinder. The prism hump does look big in the photos, and Pentax have sought to differentiate themselves via good viewfinders before, so it bodes well...

Now, with a FF body, that presumably will be the same .... the magnification will be set to give us 100% of the image in the actual frame. But, put an aps-c lens onto the FF body .... the viewfinder is the same ..... surely because the aps-c lens projects a smaller image circle, will we not in fact see the vignetting and dark areas around the edges in the viewfinder ? And does this issue not mean that with those aps-c lenses the viewfinder magnification has to 'zoom' in a bit in order to correctly fill the viewfinder with the reduced image frame (100% view of the 'cropped' frame) ?

Now imagine you are looking through the new FF, it has a wider FOV with the same lens. The size of objects does not change, but your window has just become larger.
The question now is how does the camera show the reduced FOV when the larger view is the normal one. There could be a mechanical masking, similar to the panoramic mode on some film cameras. There could simply be etched lines on the focusing screen to show the reduced area. There could be electronically projected lines. There could be a hybrid optical/EVF system.
Whatever the solution, the size of any object in your viewfinder will stay the same, only the FOV will change.
If you want to know how big the viewfinder will be, look through a film SLR.
