'Dual ISO', 'Dual Native ISO', or 'Dual Gain Amplification'. Almost every Sony camera has it. In APS-C since the 6100, in the A7 series since the A7R MII, The A9 series all have it, and the A1 series. Sony certainly 'admits' to it, it's not a secret and was a selling point early on. Now almost every manufacturer has it. Essentially, the signal goes through an analog amplifier, is then changed to a digital signal and then goes through a digital amplifier. There is a greater advantage on FF cameras than on APS-C. Of the A7 series, the A7 IV is the most pronounced. ISO 400 is about the same as ISO 225 or so. I have shot inside museums with the A7 IV and the 24-105/4 with no flash and gotten excellent results. My A1 is better yet, the second stage kicks in higher at ISO 500 or so, but it still delivers about ISO 250 noise. Everyone should learn where the second stage on their camera kicks in. You could assign it to a custom shooting set or a custom key to provide quick access if needed.Welcome, dear visitor! As registered member you'd see an image here…

Agreed. Sony's crappy firmware updates fail enough on their own, you don't need to help them along. -
Thank you so much for this answer! I was just having the same issue on my A1 II. It was driving me nuts.
