As you can see from the above lens specifications, the optical formula of the Nikon Z 24mm f/1.8 S consists of 12 elements in 10 groups, 4 of which are aspherical and 1 is extra-low dispersion (ED) element. It has a fast STM stepping motor, a rounded 9-blade diaphragm, and the lens is weather-sealed. In comparison, the Nikon 24mm f/1.8G ED has a slightly different optical formula with 12 elements in 9 groups, 2 of which are aspherical and 2 are ED. It has a rounded 7-blade diaphragm, silent-wave motor and other than the rubber gasket on the mount, it is not weather-sealed.

The Nikon 24mm f/1.4G ED is arguably more similar in optical design, with the same number of elements and groups, except with two aspherical and two ED lens elements. It also has a rounded 9-blade diaphragm and professional-grade build quality.

The Sigma 24mm f/1.4 Art is optically the most complex, thanks to its 15 elements in 11 groups, 2 of which are aspherical, and 7 of which are low-dispersion glass elements (3 FLD and 4 SLD). All this obviously comes with a big weight disadvantage – the lens weighs 665 grams, which makes it the heaviest lens in the group.
