Shot using the 42-megapixel Sony A7R II. Image stabilization disabled.
This series is at a reproduction ratio of about 1:13. Sharpness cuts through the scene, so peak sharpness at f/2.8 must be looked at where it actually “cuts”.
The ISO series are shown with color and grayscale; the crops are shown with color as well as R/G/B color channels from the ProPhotoRGB color space as well as a combined grayscale conversion. Thus the color noise and other kinds of noise can be understood across the ISO range.
