Despite its large maximum aperture of F1.5, it is compact with a total length of 55mm. The lens is made up of 10 elements in 8 groups, and the use of aspherical lenses provides excellent imaging power even at maximum aperture. With its easy-to-handle size and large aperture, this lens is also useful as a "night snap shooter."
Equipped with electronic contacts, the lens usage status is reflected in the Exif information of the shooting data. In addition, since it has a built-in distance encoder, it supports 5-axis image stabilization on the camera body. It is also possible to enlarge the viewfinder by operating the focus ring.
In addition to ensuring a full-size image circle, the optical design is optimized for Sony E-mount sensors, maintaining high resolution even at the edges of the screen and suppressing phenomena such as color casting.
The minimum shooting distance from the subject to the imaging plane is 0.28m. The perspective unique to a wide-angle lens and the maximum aperture of F1.5 enable images with shallow focus, especially in close-up areas.
A 12-blade aperture is used to make the aperture shape closer to a circle, resulting in natural depiction of out-of-focus areas and soft bokeh of point light sources rather than polygonal shapes.
The all-metal helicoid unit is machined and adjusted with high precision, and the use of high-quality grease that produces just the right amount of torque makes focusing feel smooth and allows for subtle focus adjustments.
The aperture click switching mechanism allows the aperture ring to be opened and closed steplessly without making a clicking sound. This eliminates the need to worry about the sound of the aperture ring being picked up during video recording, and also enables precise depth control by fine-tuning the aperture ring.
The NOKTON 28mm F1.5 Aspherical Z Mount is a large-aperture wide-angle lens compatible with full-frame (Nikon FX format) mirrorless cameras that use the Nikon Z mount. It has a large aperture of F1.5, yet is compact and has high performance. The aspherical lens provides excellent imaging power even at wide apertures.
Equipped with an optical system optimized for the image sensor of mirrorless cameras that use the Nikon Z mount, this lens has a full-size image circle and can be used with both full-size (Nikon FX format) mirrorless cameras and APS-C size (Nikon DX format) mirrorless cameras.
The lens mount is equipped with electronic contacts, enabling electrical communication between the lens and the body. The combination of an electrical communication-enabled body and the latest firmware*1 enables Exif information, in-body image stabilization (3-axis), and three types of focusing support functions (focusing by changing the focus point frame color, focusing by peaking, and focusing by magnifying the image).
The minimum shooting distance from the subject to the imaging plane is 0.28m. The perspective unique to a wide-angle lens and the maximum aperture of F1.5 enable images with shallow focus, especially in close-up areas.

A 12-blade aperture is used to make the aperture shape closer to a circle, resulting in natural depiction of out-of-focus areas, and point light sources and other objects appearing blurred in a round, soft manner rather than polygonal.
* 1Please use the latest firmware for your camera body. For cameras released before 2020 (Z5, Z6I, Z6II, Z7, Z7II, Z50), older firmware may not perform as expected or may limit some of the functions. Please refer to the camera body's instruction manual to check the camera body's firmware and obtain the latest firmware.
