Sigma 180mm f/2.8 APO Macro DG HSM at 1:1 Life Size (Doll, Nikon D800E)
Added my review of the Sigma 180mm f/2.8 APO Macro in DAP is an aperture series at 1:1 (life size) from f/5 (wide open) to f/32.
Additional aggressive sharpening is shown for the crops in order to evaluate the ideal tradeoff of sharpness versus depth of field.
