I got curious after all this news about 40 MP tripod shots... so I did a quick little test on a tripod. Here's a normal 16 MP E-M5 image with the PL25, f/4, ISO200, 1/20s: The full size is here: https://dl.dropboxusercontent.com/u/38795710/mini.jpg Here's a 4x stitch of 4x mean stacks (16 images total) using the same settings, just different framing: The full size is here: https://dl.dropboxusercontent.com/u/38795710/mega.jpg Sorry I didn't try too hard to get the framing right... I also didn't quite get the correct size after the stitch (it was only about 35 MP) so I up-res'd it in Photoshop to 40 MP. Curiously, notice the DoF appears to have gotten shallower even though it's shot using the same aperture? Here's a 200% view of the 16 MP shot to roughly match framing: Here's a 100% view of the stitched 35 MP up-res'd to 40 MP stack for comparison: And the 100% view of the 16 MP shot again for comparison: More resolution No moire Folks, if you don't mind taking a lot longer (and it probably won't be quite as good as what the Olympus does out of the box), you can try something similar too!
