Cosina has launched its new Voigtlander Nokton 35mm f/1.2 for Fujifilm X-mount. While this lens features the same focal length and aperture as its M-mount equivalent, it features a different optical design and construction specifically for Fujifilm’s X mount cameras.
In fact, Cosina touts the Nokton 35mm f/1.2 as a lens that will provide high resolving power from edge to edge without depending on the optical correction functionality of the camera while also suppressing the occurrence of color cast. It is a simple eight-element in six group design that leverages a near-symmetrical double-Gauss type layout, which means it consists of two back-to-back Gauss lenses — a design with a positive meniscus lens on the object side and a negative one on the image side. It also has a 12-bladed aperture to allow for smooth round bokeh. It has a minimum focus distance of 11.8-inches (0.3 meters), a 44-degree angle of view, and a 46mm front filter size.
The fully manual lens features an electronic chip for transferring EXIF data to the camera body from the lens, which should enable focus verification, parallax correction, and in-body image stabilization for compatible cameras. Electrical contact compatibility is only compatible with the Fujifilm X-H1, X-T4, X-T3, X-T2, X-Pro3, X-S10, X-E4, and X-T30. Older models like the X-Pro2, X-Pro1, X-T20, X-A7, X-E2, and X-M1 are not supported. A full list of supported cameras can be found on Cosina’s website.
Below is a pair of charts showing which X system cameras are and aren’t able to make use of the lens mount communications of the Nokton 35mm f/1.2 lens:
The lens is small and light, weighing only 196 grams and measuring 59.6mm x 39.8mm. It is a fully manual focus lens, but Cosina says that it uses an all-metal, high precision helicoid unit to give the lens a solid feeling of torque and smooth operation. The result, according to the company, is a manual focus lens that allows for delicate, precise focus adjustments. Aperture is controlled through a manual aperture ring that is directly connected to the opening and closing of the aperture blades with one-third step clicks for precise control.
