Very quick, busy weekend!
D800 and E on Gitzo CF with Cube, Zeiss 100mm Makro F2 at F5.6, both shots given identical treatment in LR with LR default sharpening but Camera Standard profile, shots individually WB from same spot (light shifted slightly between exposures).
Manually focussed in LV.
Ran this from F2 thru F8 and in each case the differences were similar.
91% full sized JPEGs developed from RAW.
Not a procedurally perfect test, too busy, but mildly telling. I shot a bunch more and had a quick look, including on the 24-120. I know what I think! What do you guys think?
