Thanks pinholecam on this thread (and elsewhere) for extolling the virtues of Raw Therapee. I just downloaded 5.1 and used it to process the image below.

Tamron 28-75 f/2.8 Asph lens, f6.3, 44mm, ISO200. Rested on a wall (no tripod), hence the cropped image.

A much larger (iMac desktop-sized version) is here: https://drive.google.com/open?id=0B9dwIDu9gH7FdDd5YWRsTk1pQzQ (it looks a little over-sharpened by the stepwise sharpening script I use).

Trying out some pixel shifted shots yesterday at a nature reserve. I used Motion Compensation as the water was often a little disturbed, by rare platypus, or by wind.

As expected, attempts at processing using ACR did not give good results, with clear colour issues in areas of disturbed water. Digital camera utility did seem to cope well with most of the movement.

I output 16-bit AdobeRGB TIF files from DCU and imported them into Capture One Pro 9.2, with only minimal further processing, and then C1Pro's claimed improved re-sizing algorithm (inherent to any of its size-reduced output recipes) to produce the 1200w jpgs for Flickr upload.

This first one is using a P645 300/4 ED(IF) lens, with P645-PK adapter.

I think you will love the SMC 28 f3.5, based on my own very limited experience so far ( I have owned mine for about 2 weeks, but have only shot with it maybe 10 times).

After other posts on another forum re Pixel Shift resolution images, I posted the following (finding that Adobe Camera Raw does a better job than Digital Camera Utility) in resolving my example PS image:
