NOKTON 23mm F1.2 Aspherical

Compact semi-wide lens with large maximum aperture

Features

The NOKTON 23mm F1.2 Aspherical X mount is an interchangeable lens for the Fujifilm X mount.A fast manual focus semi-wide-angle lens that covers an APS-C size image circle and it has an angle of view of 35mm in full-frame equivalent. The lens configuration uses the latest optical system that uses one double-sided aspherical element and two anomalous partially dispersed glasses out of 10 elements in 6 groups. While achieving a large aperture of F1.2, it has excellent descriptive power with excellent resolution from the widest aperture, and large blur can be obtained.

Main Features

Dedicated design for Fujifilm X-mount

The lens utilizes an optical formula optimized for the imaging sensors of Fujifilm X-mount system cameras. High resolution is maintained up to the image periphery without having to rely on the camera’s optical correction function, and color shifts are well controlled.

Information communication with the body via electronic contacts

The lens has electronic contacts to enable highly reliable electronic communication between the lens and body. Exif information, focus checking, and display according to shooting distance are supported on bodies with the latest firmware that support electronic communication (*1), and in-body image stabilization and parallax correction are also supported on certain models.

Manual focus for reliable focusing

Employs a very precisely machined and adjusted all metal helicoid unit lubricated with high quality grease to realize smooth focusing operation with just the right amount of torque. This enables very precise focusing.

12-blade aperture diaphragm for beautiful bokeh

The aperture diaphragm is configured with 12 blades to make the aperture opening as circular as possible. This means the out-of-focus areas of images are drawn naturally and point light sources etc. are drawn as soft round bokeh rather than as polygonal shapes.

Directly operated mechanical aperture ring

Like the VM mount and mirrorless mount Voigtländer lenses, the lens employs an aperture ring mechanism that directly opens and closes the aperture. The mechanism has 1/3 stop clicks so you can directly enjoy the feeling of operating it.

Minimum focus distance of 0.18 meters

The 0.18m minimum focus distance is achieved by extending the entire optical cell fully forward. A benefit of close-up shooting is that more bokeh can be obtained when capturing images at closer distances compared to further distances, thus expanding the possibilities of imaging that utilizes bokeh at maximum aperture.
