Shot with the Sony A7R in APS-C crop mode (4800 X 3200 = 15.36MP).
This scene shows close range performance at an approximate reproduction ratio of 1:8 (about 1/8 life size). It was chosen for its relatively deep 3D layout at close range (not enough depth of field until well stopped down), with the goal of seeing how image quality holds up at f/11 and f/16.
The shutter vibration of the Sony A7R could have been a factor at f/2.8 and f/4 ( a macro lens is very much like a telephoto lens in its sensitivity to vibration), but the main issue is depth of field, nor can one rule out air movement of the plant leaves for these long exposures.
f: 2.8, 4, 5.6, 8, 11, 14
sec: 0.3, 0.6, 1.3, 2.5, 4.0, 8.0
