A7r vs RX1: Purple noise on high iSO
5 months ago

Hi,
After using mainly the RX1 for a couple of days I went back to my A7r and found out that there is a weird purple-ish noise on the darker tones of images.
Both images were taken with their maximum allowed ISO setting in each camera (25600), same aperture and shutter speed and auto white balance. It seems that the A7r fared worse than the RX1.

Can anyone explain why this is?

thanks

A7r

RX1

ps. To those who might say "just use a lower ISO": I can't, I keep it auto and highest in both cameras due to my style of shooting.
