Cosina today announced that it will release the new NOKTON 50mm F1 Asperical, an interchangeable lens exclusively for Sony E-mount, in March 2024.
Equipped with an electronic contact point, the usage status of the lens is reflected in the Exif information of the shooting data. Also, since it has a built-in distance encoder, it supports 5-axis image stabilization on the camera body side. It is also possible to enlarge the viewfinder by operating the focus ring.
In addition to ensuring a full-size image circle, it uses an optical design optimized for Sony E-mount sensors. High resolution is maintained even to the periphery of the screen, and phenomena such as color cast are suppressed.
The first lens surface uses a GA (ground aspherical) lens produced in-house. It has become possible to simplify the lens configuration while ensuring high performance, and it has achieved both high-level image quality and a tight style despite its ultra-large aperture.
By adopting a floating mechanism that moves the lens groups independently according to the shooting position, stable image quality is ensured from the shortest shooting distance (0.45m) to distant motifs.
The suggested retail price is 240,000 yen (excluding tax).
