In my experience it slows the camera down a bunch to use it (takes about a minute to process) and in the end doesn't really improve the image that much. Maybe Olympus's version will be better. My understanding from what Bruce Banner has done with experimenting with multiple images post processed in this fashion is that more than four images seldom adds much to the image quality.
I thought pixel shift and hires modes were different, where ps stacks all pixels to improve color and detail, and hi-res stacking them to increase resolution? I don't think I've read that hires mode improves dynamic range or noise, but might be mistaken. My EM1 didn't have that mode, so I didn't have an opportunity to play with it.
Ps is quite cumbersome to use, I just realized Capture one doesn't support it, so proper support comes only from raw therapee and silkypix..
