Sony FE 24-70 GM F2.8 flat field performance
I wanted to see how good the new 24-70 GM lens performed when photographing something flat. Its important for photographing art, something I do, as well as many other types of images. This collection includes the full sized image as well as 1:1 crops of each corner and the center of the painting. The image was made handheld at F2.8. Normally I do art documentation with a tripod, strobe lights and polarizing filters on the lights and the lens. This test does illustrate that the lens has, in my view, outstanding flat field performance.
