Get yourself a shift lens for 0!

Just came across this thread on the other Pentax forum but have never seen it mentioned here!
http://www.pentaxforums.com/forums/pentax-k-3/239169-german-color-foto-claims-k-...

Tried on the K-5 and it works ! Looked for it on the K-R but its not there!
K-3 II, K-3 and a K-70 from SRS (having now relegated the K-30 /"K-50" to a backup body), & some Sigma and Pentax lenses (and a lot of old 35mm gear!)

The link takes me to the Pentax Forums home page, not the specific thread?

That's a good idea. Shows that all those bodies could have had a larger than APS-C sensor too given that stitching the images without moving the camera gives you a larger image.

You mean the sensor could be the same size as the back of the camera!

Good idea but a kludge! Automate it please, Ricoh!

Is it really a tilt-shift effect though? Or does it just create a larger field of view?

It's the same as a rising front on a view camera.
Same as a shift lens.

Thanks for correcting the link - have not been very well lately (combination of problems!) and so did not notice the error.

Nevertheless it has generated some debate!

Looks like you can do it on the K-30 as well. Thanks for the tip. I'll try that out.

http://c758710.r10.cf2.rackcdn.com/files/support/manual/1340052607_Manual_K-30_E...

p153 of the manual or p155 of the PDF.

I wonder how much extra width this gives a lens. Looks like quite a bit. If I am using a 28mm lens with composition adjust what lens length would give me the same image without composition adjust...?

Have to see how much extra it gives the Sigma 8-16mm.
Given there is in camera stitching with some camera brands it surely could be automated. Get full frame from an APS-C camera, or almost!
Thanks for posting the links. I was aware of it but hadn't thought how useful it could be.

Yes doing it in camera would be really cool. I've never done much stitching in post. I used to do it with some Canon own brand utility which seemed to work ok.

Looks like it can't be done in Lightroom.

This might be worth a look: AutoStitch

Photoshop and Elements can stitch images. There are many others.

Thanks for the tip.

I don't have either at the moment so I'll probably try to find a free / open source solution initially.

Not tried it but Microsoft ICE is said to be pretty good, and free!

Another free alternative from Serif:

There and many more.

Except the main reason the sensor can shift is to allow shake reduction to work - if the sensor were larger in the first place that would man you would need an even larger image circle if you wanted to retain sensor shift shake reduction.
