Could you give me a comparison between the 4 shot and the 16 shot? As the piece in the middle (Is it a register?) may look a bit sharper on the 4 shot? But that might just be the downscaling of the 16-shot which makes it look a bit softer.

The 4-shot and single shot were upsampled to 240 megapixels before compositing. There was no downsampling as that would have thrown away detail. This could make the single and 4-shot parts appear sharper, but the 16-shot bit is clearly *resolving* more.

Don't forget, we're pretty much up against diffraction limits at this resolution even at f/3.5 (< 2 micron effective pixel pitch) . I suspect that's the main cause of any softening you see here.
