Optical construction

Optical construction comprises 17 elements in 15 groups, including three aspherical elements and two 'ED' extra-low-dispersion elements, and both Nikon's Nano Crystal Coating and the newer ARNEO coating for flare, ghosting and coma suppression. Meanwhile, distortion is well-controlled and nine rounded aperture blades should help keep out of focus highlights circular at wider apertures.

Because of the exceptionally wide dimensions of the Z-mount, the rear element of the lens can be very large, helping to keep light rays near-perpendicular when they reach the sensor.

Nikon describes the optical construction of this lens as 'symmetrical', and in theory this should mean that the Z 50mm F1.2 S is capable of high resolution at all apertures, across the frame. This is obviously something that we want to put to the test as soon as we can.
