AF Micro-Nikkor 60mm f/2.8D

D500 @ x 0.27

This lens is an excellent performer on a D500. Optimal sharpness across the whole sensor is achieved at f/11 with only a small decrease from the peak centre sharpness achieved at f/5.6. Chromatic aberration and vignetting are well controlled from f/5.6 stopped down

Resolution: This lens achieves excellent resolution at f/5.6 but the corner resolution is not as good as seen in the Zeiss Milvus 100M

Chromatic Aberration: Modest from f/5.6 stopped down

Vignetting: Moderate at all apertures

Macro Sweet Spot: f/11 (even across the whole frame)
