Cosina will expand its RF lens lineup in April with the release of the Voigtlander Nokton 75mm f/1.5 Aspherical lens for Canon’s mirrorless mount.

The lens, which is already available for Leica rangefinder VM-mount, will be released in an RF version with a modified housing design. Before last month’s CP+ show in Yokohama, Japan, the business announced that it would offer this prime lens to other mirrorless mounts. While it was mentioned that it would be available in Nikon Z and Sony E mounts, the Canon RF mount version is the first.

Cosina describes the Voigtlander Nokton 75mm f/1.5 Aspherical as a large aperture medium telephoto lens that is compact but performs well optically even when set to its widest aperture of f/1.5. While it is a manual focus lens, like all of Cosina’s Voigtlander optics, the optical arrangement has been tuned for the RF mount, it is compatible with both full-frame and APS-C sensors, and it communicates electronically with the camera it is attached to.

As a result, the Voigtlander Nokton 75mm f/1.5 Aspherical will perform properly with Canon’s in-body image stabilization (IBIS), three types of focus assist capabilities (enlarged display, peaking, and focus guide), and will communicate EXIF data.

In an unprecedented design decision for a lens as fast as the 75mm f/1.5, Cosina made the aperture drop down to f/32, allowing it to create exceptionally shallow depth of field at one end and highly deep focus at the other.

The optical arrangement consists of seven elements divided into six groups, including three extra-low dispersion lenses and one aspherical optic. The aforementioned wide aperture range is aided by a 12-bladed diaphragm adopted from the VM-mount variant.
