The 135mm f/2 APO-Sonnar focuses to 1:4 (1/4 life size covering an area of 145 X 96mm).
Since the 135/2 APO-Sonnar is not a macro lens, one might question its sharpness at its closest focusing distance: can it substitute down to 1:4 for a macro lens like the 100mm f/2 Makro-Planar?
Flat field “repro” work is not the concern here; sharpness and bokeh are.
This image is very close to 1:4 which is the minimum focusing distance of the Zeiss 135/2 APO-Sonnar. True macro work might be deemed 1:2 or 1:1 or 2:1 or more, whatever floats your boat— it’s close range.
