Canon R5 Mk Ii Drops Pixel Shift High Res – Is Canon Missing the AI Big Picture?

It's a GH6, so probably the same system roughly...

And yes that's what I said, sorry if I wasn't clear.

It does get more "pixels" resolution, the image file is 100MP, but it's certainly not 4X the image resolution in terms of image quality. Not that I was expecting that, but it's not even a middle ground that I consider usable, at least not good enough to use over a normal 25MP picture.

I've done a bunch of landscape shots (with a very solid tripod, camera in silent mode, shutter release delay, no wind, etc) and generally I've found the results mixed-to-bad..

Like I said, it seems like the algorithm has a hard time stitching the images together often so if you zoom into the details (and really if you're using this mode, it's ostensibly because you want more detail), things get fuzzy or muddy in most of the pictures I've taken.

To be fair I took maybe 20-30 test shots in the first 6 months I owned that camera, and I haven't gone back to the mode since.. Maybe some of it is user error, but I really did try to make it work because it seemed like a cool feature.

Do you have a remote shutter trigger? I think pressing the shutter button can count as too much movement for these systems.

What I struggle with - isn't even let's say walking around, small air movements etc. producing enough tremor to influence this? We're talking about moving the sensor/scene by one half of a pixel size which is a miniscule amount (2 micrometers or so).

Yes, hence tripod and photographing buildings, as mentioned in an ancestor comment[1]. On a windy day (enough to shake the tripod) or on shaky ground (cars, trams) I guess this might still not be enough.

I do not but as I mentioned in my previous post the camera supports a shutter delay (to account for the movement of pressing the button), which I used for this mode.

I feel like I really did everything I could to create the ideal conditions for this mode to produce good results, and it simply didn't.

That said, all this talk has made me want to go try again.. :-)

My S5IIx allegedly can do a pixel-shifted 96MP high resolution shot up to 1 second _hand-held._ I haven’t tried it and probably never will.

Hah yes the GH6 also claims that the IBIS (in-body image stabilization) can allow you to use the pixel-shift mode handheld but given the mixed results I've had on a tripod, I also have not tried this.

GFX 100 has similar mode. It’s not surprising that stitching multiple images of a moving subject , or thousands of moving subjects in the case of leaves and blades of grass, fails to produce something similar to a pixel shifted image of something static.
