The NOKTON 35mm F0.9 Aspherical X-Mount is an ultra-fast standard lens that achieves the widest aperture among Voigtländer’s X-mount interchangeable lenses.
The lens features compact styling with an overall length of less than 65mm for ease of handling, while also rendering a crisp and
clear image even at full aperture. In order to satisfy all the design goals we have adopted an in-house produced GA (ground aspherical) lens on the first surface of the lens.
The reason why we designed and manufactured a GA lens, which is more difficult to produce than a general
mold aspherical lens is that it is possible to use higher melting point and high refraction glass. By manufacturing an aspherical lens from a glass material with a high refractive index, we have created an
ultra-fast lens in practical size.
The lens construction consists of 10 elements in 8 groups, including a GA lens and double-sided aspheric
element, and despite its ultra-large aperture of F0.9, the minimum aperture is small at F22.
Along with the accurate feel of manual focusing when the entire lens group is moved along the all-metal lens
barrel, you will also feel the responsiveness of direct operation when opening and closing the mechanical
aperture ring.
The lens includes a dedicated metal hood that can be reverse mounted for portability.
