Cosina Teases Their First RF Mount Lens

Cosina, the Japanese manufacturer of photographic equipment, has recently announced their plans to release their first RF mount lens. This new lens is designed to be compatible with Canon’s mirrorless cameras and will provide photographers with a high-quality, versatile lens for a variety of shooting situations.

What is RF Mount?

RF mount is a mounting system developed by Canon for their mirrorless cameras. It features a larger diameter and a shorter flange focal distance compared to the previous EF mount, allowing for better optical performance and faster autofocus speeds. With the release of the RF mount, Canon has been working with third-party manufacturers to expand the range of lenses available to their users.

Cosina’s New Lens

Cosina’s new lens for the RF mount will be the first in their Voigtländer line of lenses to be designed for mirrorless cameras. The company has not yet released any technical specifications or pricing information, but the lens is expected to be a high-quality, versatile option for photographers using Canon’s RF mount cameras.
