I used Imatest to see how the 100mm Macro performs when paired with the 36-megapixel Nikon D810. At f/2.8 the lens scores 2,292 lines per picture height on a center-weighted sharpness test, a figure that exceeds the 1,800 lines we like to see in an image.
Quite sharp when stopped down; 1:1 magnification; Internal focus design; Compact; Available for multiple systems; Long focus throw; Attractive price point
Some edge softness at wide apertures; Manual focus design is not for everyone; Omits optical stabilization
