kon’s Z lenses tend to be much sharper than the older optics, an improvement that had me itching to try the system’s first macro lens. The Nikon Z 105mm Macro, formally called the Nikon Z MC 105mm f2.8 VR S, brings a true 1:1 ratio to the company’s full frame mirrorless system. The 105mm can shoot from about a foot away. So how does the Nikon Z system’s sharpness translate when up close?
