NOKTON 40mm F1.2 Aspherical

Smooth very blurred bokeh

Features

The NOKTON 40mm F1.2 Aspherical is a large aperture manual focus lens. Covering a full-frame image circle, the optical design is optimized for the image sensor of the Nikon Z system cameras.  The lens construction consists of eight elements in six groups, two of which are double-sided aspherical lenses. Despite its compact size, the lens achieves an astonishingly large F1.2 aperture.  The lens offers reliable optical performance from maximum aperture and gentle very out-of-focus bokeh effect.

Main Features

Designed exclusively for the Nikon Z mount

Optics optimized for the image sensors of mirrorless cameras with the Nikon Z-mount are implemented. The lens has a full-frame image circle and can be used with both full-frame (Nikon FX format) and APS-C size (Nikon DX format) mirrorless cameras.

Information communication with the body by electronic contacts

This lens is equipped with electronic contacts and realizes communications between the lens and the body. In addition to Exif information and in-body image stabilization (3 axes), by combining with a body compatible with communications and the latest firmware*1, three types of focusing support functions ( [1] focusing by color changing of the focus point frame [2] peaking function focusing and [3] focusing with the enlargement button) are supported.

Manual focus for reliable focus operation

Adopting a full-metal helicoid unit processed and adjusted with high precision and high-quality grease that produces an appropriate torque, focusing with a smooth operation feeling is realized. It enables fine focus adjustment.

Beautiful bokeh effect with 10 aperture blades

A 10-element aperture is used to make the opening formed by the diaphragm blades closer to a circular shape. Out-of-focus areas are rendered naturally, and point light sources are rendered with a soft, rounded bokeh effect.

Versatile angle of view

The angle of view of the 40mm focal length is equivalent to 60mm on an APS-C size camera, making it a versatile lens that can be used as a standard lens on both full-size (Nikon FX format) and APS-C size (Nikon DX format) cameras.

*1 Please use the latest firmware version of the camera body; bodies released before 2020 (Z5, Z6I, Z6II, Z7,Z7II, Z50) may not perform as well with older firmware or some functions may be limited.Please check the body's instruction manual for information on checking the firmware of the body and obtaining the latest firmware.
