From the editor
In summer 1955, the lens was adopted as a standard lens for the Chiyotax IIIF. It was also offered as a standard lens for other Japanese screw-mount cameras, such as the Honor, Leotax and Melcon.
The Leotax T camera manual states that the lens has improved anti-reflective coating, excellent resolution across the entire frame at all focusing distances, including close-ups, and astigmatism, spherical aberration and other aberrations are perfectly corrected.
