Quality
To measure and compare the noise levels on the Nikon Z7, I shot the following scene in RAW+JPEG mode at every ISO value and took 100% crops from each for the tables below. I repeated the test with the Nikon D850 and Sony A7r II using the same lens and have presented them below with the D850 in the left column, the Z7 in the middle and the A7r II in the right. JPEGs in the first table are straight out of the camera, while RAW files in the second table were processed in Adobe Camera RAW using sharpening of 50 / 0.5 / 36 / 10, and with noise reduction disabled to really see what’s going on behind the scenes.
