Design and Build
The SEPTON 40mm f/2 is built with an all-metal helicoid for smooth, precise manual focusing. Its pancake profile makes it ideal for travel and street photography. A dome-shaped screw-in hood is included, and the lens accepts 52mm filters whether the hood is attached or not.
Optical Design
Cosina drew inspiration from the classic Orthometar optical design, adding one extra element to create a 7-element, 6-group formula. This delivers a fast f/2 maximum aperture in a remarkably thin package. The 40mm focal length sits between wide-angle and standard, offering flexibility for portraits, landscapes, and everyday shooting.
Features and Functionality
- Electronic contacts ensure Exif data is recorded.
- Distance encoder supports 5-axis IBIS on compatible bodies.
- Focus magnification activates automatically when turning the focus ring.
- Compact size and lightweight build make it a practical choice for travel and documentary work.
