At 70mm, this test represents a head and shoulders portrait, a very reasonable use for the 70mm setting. Reproduction ratio is ~1:15 based on an image width of ~22 inches. Close range, but definitely not macro range.
The camera was tilted down slightly, to afford a generally better alignment with the 3D nature of the subject. This effects the nominal plane of sharpness cutting through the scene.
Lighting was a mix of window light and halogen fill. RAW processing added a 0.15 push, and white balance was done off the 2nd-brightest gray patch.
For this comparison, I increased my normal sharpening amount to Amount=80 to really bring out the fine details possible. This aggressive level of sharpening is just fine so long as the exposure is full ETTR, as it is here.
