I am definitely not a pixel-peeper. But while some of you asked for them, here they come: very high ISO JPG samples straight from the X-Pro2. I have shot consequently three different scenes at ISO8000, ISO10000, ISO12800 and ISO25600. The images below are all unscaled 100% crops of those JPG files.
To make sure you can examine the 1:1 image quality of those shots, click on any particular image and when it opens in a lightbox, drag it to your desktop and open in a photo editor of your choice. Make sure you activate the 1:1 view mode.
