Mighty big compound loco got to more powerful than UP Big Boy.D700 + 28/2.8 ais @f/5.6 cropped.
The lens shows an apparent issue upper-left near the pole transformer, soft focus but sharp focus elsewhere closer and further. Maybe field curvature or something else, not sure (sensor is clean). Did same thing at f/8 and f/11, first time using/testing this lens outside.
