They've been well informed and accurate so far. Looks quite nice although no spec yet.

Well, it's been officially anounced now. I can't frickin' believe it, after all these years of waiting!!! Finally, Pentax! Let's hope it'll be as good as the hopes are high.

The press message mentions a crop-mode (compatable with DA series aps-c lenses) which makes good sense and will help many of us to ' get going', especially if we don't yet have FF glass that covers every angle.

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 have crop mode (Dx) on a Nikon body Nigel, it's just a menu choice in the software options. If a Dx lens is attached, it switches automatically. Maybe the Pentax will be the same and if so, makes it even easier to use all lenses.

Best regards

Ok, thanks, so it could be automatic ... That would be handy. But I'm curious about the technology .... I'm right, an I, in thinking this requires a change in viewfinder magnification in order to avoid seeing the dark edges around a crop lens. At present our viewfinder magnifications are fixed ... Does that now have to change on the FF model, with some sort of zoom mechanism in the viewfinder to zoom in to the aps-c setting? On your Nikon, does this happen? Do you hear some kind of zoom action happening? I'm thinking something has to actually move inside the viewfinder?

As far as I know Nigel there is no mag factor change. The smaller "cropped" area is shown in the viewfinder with illuminated lines. I don't have any cropped Nikon glass, it's all FF so I have never used the function.

Ok, thanks, I guess that's another way to do it ... But I'd have though that is there was any dark areas around the edges, that would look quite distracting in a viewfinder ... Also wouldn't the view become a bit small really? I'd have thought a way to zoom in to fill the viewfinder frame would be ideal .... Maybe not practical though?

Nigel, assuming the magnification is the same, you'll get exactly the same view in cropped mode as you do with your apsc dslr.

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...

Will, I'm still not really understanding ....a viewfinder is magnified to show a 100% view of our image. For now, that means we see the 'cropped' size aps-c image circle magnified to show the complete frame.

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) ?

Imagine that you are looking through your K-7, you see the image at almost life size.

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.

Without meaning to dampen our spirits too much, I hate it when Pentax say "in development".

Didn't the 645D take about five years from announcement to fruition......!!

It was before my time, but did Pentax not announced a full frame camera "in development" in 2001.

The only date I'm interested in is when will it fall to 800 like the Sony A7 is NOW!

That's a first generation model built by a company who seem to treat camera releases like any other consumer electronic devices. It's a superseded early version, and there will be plenty of A7 users kicking themselves that they didn't wait... To buy a later model which has added more features (the 5 axis stabilization is one thing). That's why its cheap now .. Old model. The Pentax FF will be longer lasting and stay the distance much better than that.
