Cosina Unveils Super-Fast Nokton 50mm f/1 Lens for VM-Mount

Cosina has announced the Voigtlander Nokton 50mm f/1 Aspherical lens for VM-mount, which is the fastest lens it has ever produced.

The 50mm f/1 lens is constructed of nine elements in seven groups and features a "grinding aspherical surface" (GA) element that Cosina says was produced in-house and used on the first element of the lens. The company says that it was difficult to control the manufacturing of this style of aspherical lens when compared to the general molded approach, but did so using high melting point and high refraction glass. Cosina says that the goal was to make a large diameter lens that was still compact and that with a wide-open aperture of f/1, the goal was to provide very large bokeh reproduction while still being sharp.

Cosina says the GA element made it possible to simplify the lens configuration while also ensuring high-quality performance, resulting in a lens that could be performant as well as compact. The lens weighs 484 grams (about 17.1 ounces) and is 73.6mm in diameter by 55mm long (about 2.9 by 2.2 inches). Cosina says that in addition to suppressing vignetting by compressing the total length of the lens, it also has a good balance between the body and the lens from an aesthetic point of view.

The aperture has a range of f/1 through f/16 through its 12-bladed diaphragm. The front filter element is 62mm and the lens has a 47.8-degree angle of view.

The Cosina Nokton 50mm f/1 is a manual focus lens, and the company used an all-metal helicoid unit that it processed and adjusted with high-precision and high-quality grease that it says produced "appropriate torque" for a lens that focuses smoothly and provides the capability of fine focus adjustment.

The lens is also equipped with a rangefinder interlocking system, which enables close focusing near the maximum aperture. As such, it has a rangefinder interlocking range of infinity to about 0.9 meters (depending on the camera).

The lens supports a full-frame 35mm image circle and the VM-mount is compatible with Leica M. Cosina says that not only can it be used with a rangefinder-linked camera, but it also has a solid design balance when attached to mirrorless digital cameras via a mount adapter.

The Cosina Voigtlander Nokton 50mm f/1 lens will be available in January 2022 for 225,000 yen, which is about $1,984.

Cosina Launches Voigtlander 50mm f/1.5 Heliar Classic for VM-Mount

Cosina has announced the Voigtlander 50mm f/1.5 Heliar Classic lens for VM-mount that it says was designed in "pursuit of a classical image that modern lenses do not have." The optical design is intentionally imperfect to mimic a true vintage lens and show various aberrations.

In short, the Voigtlander 50mm f/1.5 Heliar Classic has all the hallmarks and desired features of a vintage lens, but is brand new.

The company says that the bokeh combined with coma flare and a single coating finish gives the lens a unique character with how it renders images. This is of course exacerbated by the wider apertures of the lens but can be toned down by closing the aperture to f/4 where the company say the performance is "equivalent" to that of other Voightlander VM-mount 50mm lenses.

The "classic" nature of the lens and its imperfections is due to the relatively simple optical construction: it is made up of six elements in three groups. Cosina says the optical design is made to intentionally express aberrations when wide open and provides a "classical bokeh and flare not found in modern lenses." The aforementioned single coating on the surface of the spherical lens is intentional and Cosina says this reproduces a classical color tone that existed before multi-coating became common and the norm.

The aperture is open at its widest at f/1.5 -- which Cosina says is a larger aperture than the limit of helia type lenses -- and its minimum aperture is f/16.

This manual focus lens has an all-metal focus ring that is knurled with a diamond pattern that Cosina says was made using a special cutting tool to improve operability and prevent slipping in both the rotation and optical axis directions. Also, in addition to practical reasons, the company says the pattern looks nice. Cosina has also used an all-metal helicoid unit that has been processed and adjusted with high precision to provide a smooth focusing operation with just the right amount of torque.

The bayonet-type VM mount is compatible with the Leica M-mount and the lens supports a full-frame 35mm format. The Cosina Voigtlander 50mm f/1.5 Heliar Classic will be released in September for 90,000 yen, or about $820.
