Voigtländer Fuji-X Nokton 0,9/35 mm asph.black

NOKTON is a title given to fast lenses with an open F value of
F1.5 or less among Voigtländer lenses.
The merit of fast lenses in modern times, where the low light
sensitivity of image sensors has increased, is that the large bokeh
at open aperture can be used for a photographic expression.
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.
