Interesting.. This pentax patent describes an EL-display in the viewfinder, which allows one to move the mirror up and use the ccd for contrast af and metering while displaying a digital image in the viewfinder when half-pressing the shutter button..

I'm starting to wonder if this is the "revolutionary" new feature.. since there is supposed to be something "special" about the viewfinder..
That would indeed be spectacular.

A hybrid viewfinder would be spectacular, indeed!

It could have been done, it is technically feasible. The press text includes no hint in this direction. But it could have been left out on purpose. To "shock" people (in ogl's language )

It's dangerous machine gun. Could kill 6 in a tick of the clock.
SO 6fps. That's great if the AF can keep up and its predictive abilities too.

It's a SHIFT lens, not a TILT lens
How much can the sensor move in each direction? If it is able to move +- 6mm horizontally and +-4 mm vertically under user control this would be sufficient to cover a full 24x36mm frame. This would be mostly useful for tripod use, as it requires 4 exposures stitched together as a panorama. However, it would turn the K-7 into a pseudo-FF camera and allow us to make good use of existing FF lenses (especially wide angles).

"Sad day for a RAW shooter" is because those image modes are for JPEG. If this button really is for image modes, that means that RAW shooter will have second button, which is completely useless for him. The first one is RAW button.
Sorry, I don't get this "sad day" sentiment at all.
Pentax has not taken away any dedicated buttons for RAW shooters, they are adding many dedicated one press buttons for the K-7! By the same token, WB button would be useless to you as well.

Just compare it with K20D - those 4 way navigation button only adjust focus points - and does NOTHING if you use single focus point. So as a RAW shooter, you have NOT LOST any functionality of single press buttons. Some of you may have use for the now separate ISO, WB, drive, flash etc; some may not. I mean there is a large part of the camera - image processing and JPEG algorithm that a RAW shooter would never use anyways; the same would apply to specific buttons and functions.

Seriously guys,

Look at the button on the right of OK button:


what is that Hexagonal button on the right for?

Looks like the picture modes from the previous K bodies.

Abstract:

" According to the present invention, even if there is a line sensor array or an area whose amount of received light is not monitored by any monitor sensor array, either the amplification factor is reduced or the maximum integration time is shortened to make the line sensor array perform the integration operation again in the case where an image signal reaches a level of saturation, and a false focusing operation which may be caused by output saturation is prevented from being carried out. In the case where the maximum integration time is shortened with no reduction of the amplification factor, the time necessary for the re-integral operation is shortened, which reduces the operating time of the focusing operation.

That's very interresting. What's the source?

Speculations in that direction has been around for a while, since the patent has been on the forums at least since last year. But now we have a camera to speculate about that might implement it.

Shifting lens groups have nothing to do with sensor shift. You cannot correct perspectives that way, unless you tilt the sensor, but here you loose focus.

Please explain. Lenses are designed to throw an image on a flat surface; so if I move the sensor a bit to one side it will not change the plane of focus.

It's probably too early to dig into this too much. My current idea is that the sensor can be shifted just a bit. So that, if you take an image, say of a building, where you align your camera horizontally to get the edges of the building parallel, you shift the sensor down as much as magnetics and image circle allow to capture more of the building. Of course, a similiar effect could be achieved via post-processing as well.

Tilt is different and cannot be emulated via post-processing.
