This series at distance assesses sharpness on a target that is as demanding as anything can be. The slightest deviation in lens assembly would show asymmetric sharpness and the target is planar, revealing any field curvatures issues. Together with the very fine details, it is a serious challenge to any lens.
Includes images up to full resolution from f/3.5 through f/11, along with crops.
