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.

* 1 This product is equipped with electronic contacts, but there are restrictions on the body that can perform electronic communications. Please check the above list of communications compatible models.
* 2 It is recommended to change the depth of field display to the film standard (the same value as the depth scale engraved on the product) in the body settings.
* 3 If the F / W is less than the stated F / W, the performance may not be exhibited or some functions may be limited, so please use the latest F / W.
For checking the F / W of the body you are using and obtaining the latest F / W, please check the body instruction manual.
* 4 When using with X-T2, it is possible to display with aperture number by changing the aperture value display setting from TNo to FNo in the settings.
* 5 When using with a model that does not support electronic communications, change the body setting [Release without lens] to "Allow".
