Sensor shift

Can anyone point me in the direction of examples of architecture or interior shots showing sensor shift and non-sensor shift with this feature, to show what this feature can do in real world application? I don't have a k-5, nor do they sell them in my city of 3 million people, so I can't try it myself. The article on the front page peaked my interest in this, but the shots of a printer from 3 feet away doesn't really show me much. I am assuming it doesn't shift enough to compete with a shift lens, but I was curious to see how far it actually shifts.

Not entirely relevant to your question, but if you are looking for a K-5 you can get them online, I know Amazon carries them (new) for less than $750.00

Hope that helps a bit.

Welcome to Camera Craft! They are in Rockford, not sure how far that is. There is also a workshop being held there on May 5th apparently sponsored by Pentax. They are advertising "free trial use of Pentax camera equipment"

Please note that it can only shift, not tilt, so it can't straighten vertical lines and that sort of thing. Basically it allows to move around the rectangle a bit after you've locked down your tripod, so up<->down, side<->side, and rotation (straighten horizon line). So it is a bit like the crop tool in Lightroom or Photoshop (with a fixed size rectangle), but it isn't going to create any special effect or correction like a real tilting or view-camera lens on a bellows could...

Do you know of a good link for more info on the tlit / shift thing? I'm interested in playing with that as well but every time I thing I understand it my brain starts to hurt.

Here's a start:
Scheimpflug principle - Wikipedia, the free encyclopedia

This might be a bit more user-friendly:

Maybe a tilting sensor could be a feature enhancement for the upcoming K-whatever. Hopefully, it'll come with a decent live view implementation as well.

If it shifts--then it straightens lines--but whether the shift is significant is another story.

This has more specific info. www.dpreview.com/forums/post/40768757

If correct the shift is about 1.5 mm--I would think this is very minimal (on Nikon full frame PC lens 28mm or 35mm as I recall a maximum of 11mm shift is possible--even with the 1.5 factor Pentax dslr vs. FF).

Thanks, but I think that's about two hours driving, each way.

Shift is what straightens vertical lines, not tilt.

Turn any Pentax lens into a shift lens: Composition Adjustment - YouTube
This looks just like the one I discussed in my thread topic that started this whole question.

Yeap, that's what I am trying to see an example of. 1.5mm isn't very much, so other than for minor adjustments in macro, I am not sure what this does for you.

Depends on the lines, but yes I should have been more clear...
