Not bad at 64,000 ISO.


Curious how the ISO steps have departed from doubling up each time, e.g. 100, 200, 400 ... and now have values like 64000 where the digits "64" are no doubt there for some reason - perhaps aimed at making some shooters feel comfortable - a bit like "ISO" itself!

... 800, 1600, 3200, 6400, 12800, 2560, 51200, ???, 102400 ...
