History and technical features 

The Pentax MX was a 35 mm single-lens reflex camera produced by Asahi Optical Co, later Pentax of Japan between 1976 and 1985. It was Pentax's flagship professional SLR until the introduction of the Pentax LX. Internally, the MX is essentially a smaller, lighter version of the Pentax KX, and otherwise has little in common with the rest of the Pentax M-series. However, the MX was designed as the mechanical twin sister of the remarkably successful entry-level Pentax ME.

The MX was solidly built, and featured a fully mechanical construction, including a mechanical shutter of the horizontal cloth type. Only the light metering system was dependent on batteries. The MX is all manual: it does not feature autofocus or autoexposure modes such as aperture-priority, shutter-speed priority, or full program.

A number of accessories were produced, among those: Focusing Screens

SC1: ground glass, split image device, microprism ring (standard)
SA1: ground glass, microprism patch
SA3: ground glass, microprism patch, for wide aperture lenses
SB1: ground glass, split image device
SD1: ground glass, cross collimator
SD11: aerial image, cross collimator
SE: ground glass
SG: ground glass, grid
SI: ground glass, axis,
Data backs, Dial Data MX and a bulk film back. Motorized winder Winder MX (2 frame/s) or a Motor MX (5 frame/s)motor drive.

Like all post-42 mm screwmount Pentax cameras, the MX accepts all K-mount lenses (with the exception of the newer FA-J and DA lenses without aperture rings).

Due to its complete lack of automatic functions, but excellent array of manual controls, the MX is often selected as a camera for photography students to practice their technique. The depth-of-field preview and self-timer functions render the MX superior in this respect to the earlier and cheaper Pentax K1000.

Características

The Cosina C1s is a 35mm SLR made by Cosina, whose products are more typically seen rebranded under other names.
While a manual-focus, manual-exposure camera may seem like a throwback in the 21st century, some users (and instructors of photography) still appreciate a camera that emphasizes the essentials, not unlike the venerable Pentax K1000. The C1s also uses the K-mount lens standard, and so can mount a wide variety of lenses dating back to 1975. On the more modern side, the vertically-traveling shutter reaches 1/2000 sec., and syncs with electronic flash at 1/125 sec. The shutter is mechanical and does not require batteries to operate; power is only required to illuminate the meter display LEDs in the viewfinder.
Both silver and black finish versions were sold.
The Cosina C1 is the same camera, but lacking a self-timer. The C2 and C3 are similar-looking SLRs but offering electronic-shutter autoexposure. The C1s is a continuation of the features Cosina developed for the CT1 Super and variations have appeared as the Dakota RZ-2000, among other names.

Características

Cosina of Japan was first of all a producer for other brands. There is a list, the Cosina List, containing more than 113 models they produced, with only a little share bearing the Cosina label.

Cosina Company, Ltd. (株式会社コシナ or Kabushiki-gaisha Koshina) is a Japanese camera and lens manufactuer. The company was founded by Mr. B. Kobayashi in 1959 as a lens factory under the name Nikō (or Nikoh).[1] Though the company has produced cameras and lenses under its own name, it is better known for making equipment for resale under other company's brand names. Cosina has manufactured camera bodies for many well-known camera brands, including Canon, Contax, Nikon, Revue, Olympus, Vivitar, and Yashica. Cosina also manufactures the modern Voigtländer Bessa line of cameras and optics, along with the newly revived Zeiss Ikon rangefinder camera and lenses.
Cosina has a long history of manufacturing optical glass and is currently capable of producing glass and plastic aspheric lenses. Their factory maintains a glass furance that is heated to 1300 C, running 24 hours a day. All glass produced by Cosina today is lead-free eco-glass. Their current glass polishing technology is able to achieve sub-micron precision. They also have vacuum-deposition optical coating capabilities that are certified to meet Carl Zeiss lens standards.[1]
In Germany, a lot of Cosina cameras and lenses were marketed by Photo Porst, for many years Germany's biggest photo retailer and mailorder house under their house brand name Porst.
One of Cosina's more interesting camera designs was the E1 Solar, introduced in 1994. The E1, a 35mm film SLR, is powered by rechargeable batteries charged by a small solar panel atop the camera prism housing.
A recent Cosina-branded product was the SW-107, identical to the (silver) Bessa L except for a different top plate, made at the beginning of the Cosina Voigtländer era for areas where Cosina was not authorized to market the Voigtländer trademark. The 107 is hard to find now.
In 2005 Zeiss and Cosina announced a partnership whereby Cosina would manufacture the new Zeiss Ikon RF camera and most of the accompanying M mount lenses.
