I still have my *istD (more exactly, my youngest grandson does).

Initially I kept it to use where I was nervous about taking my main camera (climbing etc.), but now my grandson uses it when we are out.

He is enthusiastic about it, and it's good to see it still being used.

Seems to be preparing for the tethering software..

There is also the usual 'improvements for general stabilty' line in the release doc.

I'll add my best wishes to the list....

I am a little confused (happens more and more these days)

Are we discussing the new lens (D FA 3.5-f5.6) or the old FA 28-105 (f3.2-4.5)??

I have been playing with this, and have concluded that motion correction is a software/firmware implementation that basically just scans the 4 images that comprise a PS image, and does not merge areas that show evidence of movement.

The K3II lacks the firmware to do this, so no motion-corrected JPGs straight from the camera but PDU5 will motion-correct K3II RAW files.

The Adobe pixelshift conversions don't (yet) correct for motion effects. The latest DCU5 does a far better conversion..

Based on comparing ACR and PDCU conversions of the same PS image (using the Mk 1 eyeball), I believe that ACR does combine the 4 images into 1 but does not implement any motion correction.

ACR offers no options with respect to PS, you can't choose to correct for motion or not to combine the images if there are motion related artifacts. I will use PDCU for converting PS images.

It seems that Sigma are not hanging around on this:

Just spotted this on a different forum. Sorry if it's already known.

I agree...

I downloaded a K3II DNG from Imaging-resource and processed it in PDCU 5.5.1.

PDCU allowed me to use MC on this K3II image, suggesting that MC is a Software/Firmware feature.

Crops from an area where motion was apparent:

Pixelshift ON Motion Correction OFF



Pixelshift ON Motion Correction ON



I'll play with K1 images in ACR tomorrow.
