Waiting to see an image of the right side... where the covers for the dual card slots, the remote and the tethering connectors are.

I don't believe a Z axis is possible because it would bring the sensor out of focus, isn't it?
It would be interesting to have z-axis stability for handheld macro shots. Don't think it'd have enough range to be useful though.

Visa or MasterCard?
That's why they've made dual slots, and you can toggle: both are accepted

K-3 in silver / black, and with new silver / black grip too:
Oh no! Didn't someone suggest that Pentax only introduced the silver versions towards the end of the life cycle? K-3 to be announced on Tuesday, gone on Wednesday? Be quick!

Back to the topic of the 40MP. If its a 24MP sensor, then a shift (a half of pixel in both the x and y direction or on the diagonal) would double up the resolution (48MP). By this oversampling (the traditional approach to this problem other than AA filters), you should be able to effectively remove moire (as it works in medium format cameras). The other part of the though is the use of the image processor (the improved HDR capability) which effectively takes bracketed frames and produces a RAW frame (rather than just a JPG as before). So, I am somewhat thinking that their reference to software moire removal would be a combination of techniques that would also employ sensor shifting. Traditionally, placing an anti ailaising filter or screen in front of the sensor's optical path was the solution. The side benefit of this would be enhanced resolution. This would be great for landscapes, cityscapes and architecture.

It would also be tremendous for focus stacking using the image processor's on chip HDR capability producing a RAW result.

As you can see in the picture, item nr 62 is a shield that is pulled between the EL display and the mirror, when in the up position, to avoid reflections on the latter. That is operated by a motor. Initially the design should use the mirror motor, but maybe practice has dictated other ways!

This would essentially be sort of a HUD (Heads Up Display) in the viewfinder.... Photographers too can be Top Guns....

The impression I'm getting is that the AA won't be obtained by multiple exposures. It will be achieved by vibrating the sensor extremely fast within one exposure.

If so, the the final resolution will be the natural resolution of the sensor.

But wouldn't vibrating the sensor just cause blur?

Isn't that exactly what an AA filter does?

Precisely! AA is blur at the sub-pixel level, spreading some of the image of what should be in one pixel into adjacent pixels.

If they can vibrate the sensor a sub-pixel distance within the time of a flash, that appears to do what would be needed to reduce moire in all circumstances.

The rumour elsewhere said there would be 3 strengths: off, weak, and strong.

What if, just what if the mirror/sensor in the leaked photos was actually a photoshopped APS-C sensor, when in actual fact, we'll all find a FF sensor jammed in there tomorrow?
Just a random thought......

AF is cool. But what about flash sync?!
If Pentax can bring back Nikon's good ol' 1/500s sync days from the D40 era...

Removing the AA for sharper images and then shaking the sensor to induce blur again doesn't make sense to me. Of course we can't turn off the AA filter like the shaking feature.

So it makes sense to you yet it doesn't?
