       | My Lumix camera has a similar mode (uses sensor shift and 4
       | exposures to fake a composite 100MP image from my 25MP sensor),
       | and I will say that even with a rock-solid tripod, you're not
       | _actually_ getting a 4X (or whatever) increase in quality
       | alongside the 4x resolution. If you zoom in Lightroom, the
       | resulting image is at best a bit sharper in really high contrast
       | areas, and at worst full of blatant overlapping and stitching
       | artifacts.
       | 
       | I've never figured out a good use-case for that mode, and I've
       | tried to use it quite a few times to shoot landscapes or static
       | scenes with a tripod.
       | 
       | Maybe Canon does it better, but perhaps they dropped it because
       | it's just not producing worthwhile results.

         | a decent use case for that mode.

           | I can't find it right now, but there's a YouTube video that
           | demonstrates using this mode for astrophotography. It seems
           | that a side effect of the computational process is that noise
           | gets averaged out, resulting in a cleaner (and sharper, as
           | you'd be expecting anyway) image.

         | If it's the Lumix S5 I have the same camera and as far as I

         | there being absolutely no movement in the scene. So, great for
         | buildings and architecture, terrible in forests or city
         | streets.

           | niche problem. I hope they didn't sell that as general-
           | purpose...

       | I mean, the R5 IBIS mode was always a bit of a toy. No
       | compensation for motion blur, no compensation for hand held, and
       | even when it works it's still not super-resolution without
       | artifacts.
       | 
       | But it's mostly "shoot with a tripod, nobody move", and if I'm in
       | that situation, most of the time you're better of getting a
       | smaller FOV and taking shots for panoramic stitching.
       | 
       | Is there a real pixel shift use case outside of "I want a picture
       | of my 4K monitor"?
