Nikon NIKKOR Z 50mm F/1.2 S vs Nikon NIKKOR Z 85mm F/1.2 S — Which Is Better?

The Nikon NIKKOR Z 50mm F/1.2 S from 2020 and the Nikon NIKKOR Z 85mm F/1.2 S from 2023 are both S-Line primes for the Nikon Z mount. They share full-frame coverage and the same premium positioning within the Z system, so the real choice between them is focal length, not format or brand.

The 50mm is the lighter and slimmer lens for carrying, at 1090 g and 89.5 mm wide against 1160 g and 102.5 mm for the 85mm. The 85mm is the shorter barrel, at 141.5 mm versus 150 mm, so it sits a little more compactly front to back. Both take front filters and share an 82mm thread, so the same filters fit either lens directly.

The 85mm is the stronger choice for tight head-and-shoulders portraits, because its longer focal length fills the frame from a comfortable working distance and compresses facial features. The 50mm is the better fit for environmental portraits and everyday scenes where you want more surrounding context in the frame. Both share the same f/1.2 maximum aperture, so neither lens is brighter than the other in dim light.

For small subjects, the 50mm has the closer minimum focus at 45 cm, against 85 cm on the 85mm. It also offers the higher maximum magnification, at 0.15x versus 0.11x. The 85mm has an 11-blade diaphragm against 9 blades on the 50mm.

Both lenses have weather sealing, and both support autofocus with a manual focusing ring for hands-on focusing. Manual focus is available on either lens when you want to focus deliberately. Neither offers image stabilization, a fluorine coating, or teleconverter support.

The 50mm uses a more complex optical formula of 17 elements in 15 groups, including 3 aspherical elements and 2 low-dispersion elements. The 85mm uses 15 elements in 10 groups with 2 aspherical and 1 low-dispersion element. Both designs include aspherical and low-dispersion glass to correct aberrations at their respective focal lengths.

Both lenses use internal focusing, so the barrel does not extend while focus changes. That keeps overall length constant during focusing, which helps when working close to a subject or in tight spaces.
