Voigtländer Septon 40mm F2.0 ASPH Nikon Z – Compact Full-Frame Standard Lens

A legendary optical name reborn

The Voigtländer Septon 40mm F2.0 ASPH Z-Mount revives the legendary SEPTON name originally used for lenses developed for the Bessamatic and Ultramatic SLR cameras in the late 1950s and 1960s.

The SEPTON design represented an evolution of the famous Ultron optical formula, adding an additional element to enhance optical performance.

This modern version brings that heritage to the Nikon Z full-frame mirrorless system, optimized for modern digital sensors.

Ultra-compact pancake design

With a total length of just 32 mm from the mount, the lens features a pancake-style design perfectly suited for mirrorless cameras.

Weighing only 205 g, it is highly portable and ideal for everyday photography, street photography, and travel.

The 40 mm focal length provides a natural perspective close to the human eye while also functioning as a subtle wide-angle lens.

Advanced optical design with aspherical element

The lens is based on the Orthometar optical design, known for:

• very low distortion

• short optical length

• excellent image sharpness

An aspherical element allows the lens to maintain a fast F2 aperture while keeping its compact size.

The result is high image quality with excellent detail and natural rendering across the frame.

Precise manual focus with electronic support

The manual focusing system offers precise control appreciated by photographers who prefer tactile focusing.

Integrated electronic contacts enable communication with compatible Nikon Z cameras to provide:

• EXIF data recording

• in-body image stabilization support (3-axis)

• several focus assist features

These include:

• focus frame color change

• focus peaking

• magnification assist

Premium all-metal construction

The lens features a fully metal construction, ensuring durability and high mechanical precision.

The aperture ring is finely machined and offers 1/3-stop click steps for accurate exposure control.

A screw-in metal lens hood is included and preserves the compact aesthetic of the lens.

Ideal for everyday photography and close-up shots

With a minimum focusing distance of 0.3 m, the lens is also suitable for close-up photography such as:

• tabletop photography

• objects and details

• street scenes

It is an excellent choice for both enthusiast photographers and professionals looking for a compact yet high-quality manual lens.
