Cosina Company, Ltd. from Nagano, Japan, is a Japanese camera and lens manufacturer.

Cosina Company, Ltd. (株式会社 コ シ ナ or Kabushiki-gaisha Koshina) is a Japanese camera and lens manufacturer. The company was founded by B. Kobayashi in 1959 as an optical glass factory called Nikō (or Nikoh). Although the company manufactures cameras and lenses under its own name, it is better known for making equipment for resale under the brand names of other companies. Cosina manufactures bodies for many well-known camera brands including Canon, Contax, Nikon, Revue, Olympus, Vivitar and Yashica. Cosina also manufactures the modern Voigtländer, the Bessa line of cameras and optics, and recently revived the Zeiss Ikon rangefinder camera and lenses.

Cosina has a long history of optical glass manufacturing and can currently produce glass and plastic aspherical lenses. Their factory maintains glass furance heated to 1300 ° C and operates 24 hours a day. All Cosina glass today is lead-free eco-glass. Current glass polishing technology achieves submicron precision. They also have the option of vacuum deposition of optical coatings that are certified according to Carl Zeiss lens standards.

In Germany, many Cosina cameras and lenses were sold by Photo Porst, which for many years has been Germany's largest photo and mail-order retailer under its Porst brand.

One of the most interesting designs of Kosin's chambers was the E1 Solar, released in 1994. Powered by rechargeable batteries charged by a small solar panel on the prism cover.

The new product under the Cosina brand was SW-107, identical to the (silver) Bessa L, with the exception of a different top plate made at the beginning of the Cosina Voigtländer era for regions where Cosina was not authorized to sell the Voigtländer trademark. 107 is hard to find right now.

In 2005, Zeiss and Cosina announced a partnership under which Cosina will manufacture the new Zeiss Ikon RF camera and most of the accompanying M-mount lenses.

35mm, Voigtlander

Cosina first began producing lenses under the Voigtländer brand in 1999, when it introduced 15mm and 25mm lenses for the Bessa L. Since its release, the 15mm lens was much smaller than any SLR lens of the same length and much cheaper than any compact one. Since then, the company has produced an amazing variety of these lenses with Leica screw mounts, M-mounts, Nikon S mounts (some are fully usable with Contax), as well as several SLR lenses (particularly for the M42 and Nikon F). Larger hoods are also available for many lenses and optional viewfinders. Although the lenses have the familiar Voigtländer names, all optical formulas are new.

Nikon S-mount Lenses

They are all rangefinder related and they were all available in a combination of black and silver. Wide-angle lenses were called "SC" and were sold as suitable for the old Contax mount and Nikon S mount. (In practice, telephoto lenses can be used with Contax if used at long focusing distances).

Contax lenses have not been produced since the end of Soviet lens production for Kiev, while Nikon S-mount lenses from companies other than Nippon Kōgaku have always been a rarity. In addition, the Cosina Voigtländer line includes lenses with focal lengths not available for these mounts.

Lenses for 35mm SLR

These are all manual focus lenses. The original SL series was a redesign of the 1960s or 1970s (e.g. chrome metal focusing ring without rubber pads). They were produced in several versions: Nikon F, Canon FD, Minolta MD, M42, Pentax K, Contax / Yashica, Olympus OM. All are now (2007) out of production.

  • Ultron SL 40mm f / 2
    Color Heliar SL 75mm f / 2,5
    APO Lanthar SL 90mm f / 3.5
    Macro APO Lanthar SL 125mm f / 2.5
    APO Lanthar SL 180mm f / 4

For some Nikon SLR cameras that require mirror lockup and come with separate finders, and with the option of using an accessory shoe to replace the Nikon F or F2 finder:

  • 12mm f / 5,6 Heliar Aspherical Ultra Wide Angle Lens
    15mm f / 4,5 Heliar Aspherical Ultra Wide Angle Lens

Cosina sold an “FS” adapter for use with either of these lenses with a Nikon S or Contax mount, and an “FL” adapter for use with a Leica screw mount. Since 2007, and the new SLII line for Nikon F, Pentax K and Canon EOS is designed for use with digital cameras:

  • 20mm f / 3.5 Color Skopar aspherical SLII
    28mm f / 2,8 Color Skopar aspherical SLII
    40mm f / 2.0 Ultron aspherical SLII
    58mm f / 1.4 Nokton SLII (same optical design as Cosina "Auto-Topcor" 58 / 1.4)

An all-black finish, aperture stops, a rubber focusing ring (for Nikon F-mount) and a CPU adapter set the SLII lenses apart from their SL counterparts. The new SLII lenses are designated "N" and have a machined metal focusing ring. As of 2013, the Pentax K mount models are discontinued, while the Canon EOS and Nikon F mount models are still in production.
