Voigtlander has officially introduced the SEPTON 40mm f2 Aspherical, a lens that brings a classic name into the modern era for Sony E and Nikon Z-mount users. This high-performance standard prime is designed specifically for full-frame mirrorless sensors, offering a versatile 40mm focal length that sits comfortably between a wide-angle and a traditional 50mm lens.

The lens features a compact, pancake-style design with a length of only 32mm from the mount flange. Despite its small stature, it is built with a high-precision, all-metal helicoid unit that provides smooth, manual focusing. The optical formula consists of seven elements in six groups, including an aspherical element to maintain sharpness and minimize distortions across the frame.

For those who rely on modern camera features, the Septon 40mm includes electronic contacts. This allows the lens to communicate directly with the camera body to provide Exif data and support for 3-axis in-body image stabilization. It also enables various focus assist functions like peaking and magnification. With a 10-blade diaphragm, users can expect a smooth, pleasing bokeh, while the minimum focusing distance of 30cm makes it capable for close-up work.
The lens comes with a dedicated dome-shaped metal screw-in hood, and the 52mm thread allows for easy filter attachment. Its blend of vintage aesthetic and modern optical performance makes it an intriguing option for street and travel photographers looking for a tactile, high-quality prime.
