While working on the full review, I went out across the river in Portland, Oregon and took a few mediocre photos of the city for the sake of testing out how good the ISO performance is on the a7R II compared to its predecessor and, more importantly, the a7S.

Below is a shot taken at every ISO stop starting at ISO 1250 all the way to the max ISO of 102,400 so you can judge the performance and determine where you think the camera caps out on “tolerable.”

To download these files, right click and open in new tab or save as. They are 100% straight out of camera and unedited, so you’re working with exactly what the camera renders as JPEGs.
