Geez, ISO 25600 is pretty impressive in these new cameras (R8)

Accidentally took a shot at 25600, but didn't notice until just now when I looked at the EXIF. It was from sunrise a couple days ago, when I took the camera off the tripod for a little bit to try and get some birds that were saying hi. The birds flew off so I did a couple handheld landscape shots of some forest.

There is definitely a lot of softness and noise reduction going on, but for this subject (mostly pine trees in the distance) it works. At 'preview' or 'web' size it just looks like a normal photo, only when zooming in can I tell it's a bit soft.

Maybe I should adjust my auto-ISO settings a little. I know for some subjects I wouldn't be happy with the softness at 25600.

You've discovered the power of a modern mirrorless camera.  The DR and high ISO performance in low light is remarkable.

Higher ISO performance of modern cameras is exceptional and that is why I am very comfortable while shooting sports using manual exposure with fixed shutter and aperture and letting ISO float to provide the final piece of the exposure triangle. 

In sports, softening/noise is preferable to motion blur but for landscapes you should normally be able to choose a shutter speed low enough to allow closing the aperture enough for needed depth of field while still keeping the ISO low.  Modern sensors are definitely far better in low light but there have also been great advances in processing algorithms and it is the combination that has resulted in the incredible low light performance of recent camera bodies.

The below were captured on a horribly illuminated field in the rain and the lighting at that stadium was a "colorful" mix of mercury vapor and high pressure sodium making a bad lighting situation even worse.  Captured with a Canon 1DX III and EF 400 f2.8 lens, the first was at ISO 32,000 and the last three at 25,600 with nothing other than standard DPP noise reduction applied during RAW to JPG conversion. 

Quite a difference from my first Canon 1 series, a 1D Mark II I bought back in 2005.  Top ISO for it was 3200 and ISO 1600 was fairly ugly.
