Whoa!!!! Easy sensor cleaning.
Where in the world did you find this?

I notice one more thing. The top panel is angled like in the MZ-S. Darn this is an interesting picture.
And the body looks like is all metal, not plastic. This looks like one robust piece of engineering.

The final 645D looks different(nicer) from that old style.

And the idea behind that hinged back is sensor changeability by the user, not the ease of cleaning.

and I honestly don't care how the camera looks, as long as the picture it takes look great.

Cheers,

That camera has been used a lot - look at the paint wear on the knobs. This has to be a prototype. Everything I have read said the 645d would have 2 SD slots and no CF... This body has indications of CF and SD on the top selection switch and on the top LCD. The website also shows a CF and a SD slot of the back. The picture of the preview screen of the jug shows a count of 100-9563. This thing has seen some use.

Yeah man, I understood the reason from the beginning.

I was very surprised by the photo actually, since it appears one year before the launch date.
I think they threw this info on the market to counteract the launching oh the new Leica S2 (since that one doesn't have the removable digital back).

I had this question but everyone said it was impossible. Not anymore

This is a very old picture, in the new pictures, there isn't a seam for it to open.

If you look closely at this pic you will see that the seam is still there...intriguing

I found it interesting that there was a lack of exposed contact points on the camera back of the first picture. Apparently they are built into the hinge and would have to be serviced by Pentax to change out the back. Unless the new design is different, it would seem that it was made that way as a convenience to clean the sensor only and not a removable back option.

That's a viable point BUT an interchangeable sensor would probably not be a DIY job anyways...

But it could be... It appears that the bulk of the processing is done in the camera back. I say this because the back houses the memory card, sensor and main screen and rerouting all the data to the body and back to the card would be redundant. It could have contact points because all of the communication to the back would be considered low bandwidth. The shot info like aperture, shutter speed, ISO, button presses, and when to energize the sensor for a shot would all be low bandwidth communication to the back. Like I said it could be done.

Look at a pic that shows the back straight on, and you'll see its not there on the other side. Unless the whole back opens with buttons and everything.

it looks like all the back panel (including playback, info, menu and delete buttons) is removable/interchangable, good thinking...
or is ultimate live view
