That is a real defect of Sony's implementation of pixel-shifting. They force a longish delay between frames, while Olympus normally uses approximately zero delay (though you can select a delay if you need to recharge a flash). Delays bring the risk of slow drift ruining the alignment between shots, and I think this happens often with our extreme macro setups. Even 0.5s delay is rather too long.
Edit: I should add that I don't really know the Oly delay time, just that it is too short to easily notice.

The A7RIII I tested took ~3-4sec to shoot and download the 4 raw source files. I guess now it will take <2sec. When I did the testing I made sure there was no drift or vibration happening before I took the shot by viewing live at 100 or 200%. The only movement that could occur would be due to the camera itself, which is an unknown. I expect movement of the sensor may induce a little movement or vibration, which may be why they wait for things to settle.
Never used such a program I didn't find anything about batch-processing pixel shift RAWs, but I guess a software should detect each 4 shifted frames and develop them in a batch just as with single shots...Lou Jost wrote:I hadn't though of that batch-processing problem. But I think one could make a simple work-around for that, using a macro recording program. Record the keystrokes needed to make the first conversion, and then play it back until done. Using this technique, anything can be batch-processed.
The a7R III is tempting, but I hate to pay the abusive price of recently launched, fashionable latest model cameras

I've just tested the Pentax K1 for the first time. See:
