NiSi 9mm F2.8 APS-C Lens Announced

NiSi has announced a 9mm f/2.8 lens for mirrorless APS-C cameras like the Sony a6400.

As well as Sony E-mount it will also be available in Canon RF-mount, Fuji X-mount, Nikon Z-mount and Micro four Thirds.

The fully manual focusing 9mm f/2.8 lens (no autofocus or electronic communication with the camera) is constructed of 14 elements in 12 groups and includes two double-sided aspherical elements and four extra-low dispersion elements.

The aperture range is f/2.8 through f/16 and it features a 10 straight-bladed aperture diaphragm to help create pleasing sunstar effects.

NiSi says that their SA+ anti-reflection film technology helps to improve light transmittance and also reduces lens flare. They also claim that the lens exhibits minimal vignetting and low coma, possibly making it a good choice for astrophotography.

The minimum focus distance is just 0.2-meter (about 7.8 inches) and the lens is weather sealed at the bayonet mount.

The lens measures 74mm (2.91 in.) in diameter and 78mm (3.07 in.) in length. It weighs in at 364g (12.84 oz)

The NiSi 9mm f/2.8 APS-C lens is already available to purchase for $459 direct from Nisi’s website.
