A lightweight, compact and quite affordable fixed focal length lens is introduced by Nikon for its full-frame mirrorless Z system cameras. The NIKKOR Z 40 mm f/2 is constructed of 6 lenses in 4 groups (including 2 aspherical lenses) and weighs only about 170g. It also offers a high speed of 1:2.

According to Nikon, the autofocus is driven by an "ultra-quiet" stepper motor, and the adjustment ring, which can be used to control focus, aperture, exposure compensation or ISO values, is said to be virtually silent. Focus breathing is said to have been significantly reduced so that the angle of view remains constant when focusing. The closest focusing distance is 0.29 m. The aperture consists of 9 lamellas.
The filter diameter measures 52 mm, and the optics itself measures approximately 70 mm (diameter) × 45.5 mm (length). It is largely sealed against the ingress of dust and water droplets.
The NIKKOR Z 40 mm f/2 is expected to be available from the end of September for EUR 279.
