    40mm – the ideal everyday focal length

    The 40mm focal length sits between the classic 35mm wide-angle and the 50mm standard lens, offering a particularly versatile perspective. It is equally suitable for reportage, street, travel and everyday situations. In practice, it delivers a natural, slightly wide-angle look with an added sense of space.

    Ultra-compact pancake design for maximum mobility

    With an overall length of just 30 mm, the Septon is consistently designed for mobility. Its compact form makes the camera noticeably more manageable and ensures it remains ready for use at all times. Especially in everyday use or when travelling, the lens is barely noticeable and supports a discreet, spontaneous photographic style.

    High image quality thanks to an aspherical design

    The optical design combines the classic Orthometar type with an aspherical element. This effectively reduces distortion and imaging aberrations while maintaining high sharpness and a clear image structure. In practice, it produces clean, well-balanced images with a modern look despite its compact design.

    Modern camera integration for efficient workflow

    Thanks to electronic contacts, the lens is fully integrated into the camera system. EXIF data is transmitted, and functions such as image stabilisation or focusing aids are supported. In practice, this significantly streamlines the workflow and combines manual photography with the benefits of current camera technology.
