Quote:Is available sharpness curves for these lens : Sigma 105mm f/2.8 Macro DG OS HSM mounted on nikon full frame?

Not as curve, but you are in Photozone.de and there is a lens test: http://www.opticallimits.com/nikon_ff/62...ff?start=1

Apparently f/5.6 is - as usual when a lens aperture is two stops closed - the aperture with the highest resolution (not the same as best sharpness, depending on definition of "sharpness")
