Saw this on SonyAlphaRumors https://www.sonyalpharumors.com/officially-announced-new-sony-a7riii-24-15mm-400mm-fe-lenses/
Looks remarkably familiar...
I guess this would only work for still lifes or other steady subjects, but I am really interested in seeing what kind of resolution is eked out of this new feature. Like a 42mp Foveon? Kind of cool, will be looking forward to Merrill comparisons.

Damn... This would be awesome. I scan using a DSLR. Imagine doing pixel shift and getting a more res!

Don't Olympus and Pentax already have this?

Great point. This seems ideal.

yes, Olympus introduced it with it's OM-D E-M5 II followed by Pentax with it's K-3 II, both abt. 2 and1/2 years ago or early 2015. See http://www.imaging-resource.com/PRODS/olympus-e-m5-ii/olympus-e-m5-iiTECH2.HTM and http://www.imaging-resource.com/PRODS/pentax-k3-ii/pentax-k3-iiTECH2.HTM which is also comparing the two. Pentax' moveable sensors also do image stabilsation, can simulate an AA filter ( sensor has no AA filter ) and track stars during long exposure astro-shots.
This articel compares images taken with pixel-shift of the Pentax K-1 ( "FF" 35mm 36 MP sensor, issued Feb. 2016 ) with the "Hi-Res" mode of Olympus OM-D E-M5 II and Pen-F and the ( then? ) highest-resolution full-frame offerings of Canon, Nikon and Sony ( EOS 5DS R, Nikon D810, Sony A7R II ): http://www.imaging-resource.com/PRODS/pentax-k1/pentax-k1PSR_MODE.HTM
Unlike Oly and Pentax Sony's doesn't do it "in-camera", quote: "However, unlike the system Pentax uses or the earlier, 8-shot process used by Olympus, the a7R III cannot assemble the final images in-camera. Instead four Raw files must be processed using a freely downloadable image processing application for PCs that Sony will offer. The camera must also wait between 1 and 30 seconds between shots for the sensor to settle, which is likely to exacerbate the problems of subject movement between the first and last shot." from: https://www.dpreview.com/news/34269...ursts-better-focusing-and-longer-battery-life

it is! - a dear acquaintance of mine, a professor of social antropology ( and former pro-photographer ) uses a Pentax K-1 with it's pixel shift / high res. function to digitize old scientific documents / negatives / photos. he told me results are better than from a 10.000+ Euro scanner the university, at abt. the same time, also had bought for the same job.

I realize that a few cameras have had this functionality before Sony, but I guess this is the first time I've seen the technique illustrated so plainly (it looks like a Sigma Foveon info sheet).
Do those other cameras do a similar 3/4-layer reconstruction? Raw?

Quoting Peter Krogh:
"Jay Maisel and Frans Lanting are both using cameras to scan instead of film scanners. And most high-quality museum collections are being scanned with cameras instead of dedicated scanners. (Many of these are Phase One cameras, but the D850 will probably make a dent in that.)"
