Pentax was founded in 1919 as Asahi Kogaku Goshi Kaisha, a manufacturer of eyeglasses.
In 1938 it changed its name to Asahi Optical Co. The company developed Japan's first SLR, the Asahiflex in 1952. They bought the Pentax name in 1957 from the East German VEB Zeiss Ikon. The name was a mix from pentaprism and their Contax brand.

In 2002 Asahi Optical Co. changed its name to Pentax Corporation. In 2007 Pentax was bought by Hoya. In 2011 Hoya sold the Pentax digital camera branch to Ricoh, becoming Pentax Ricoh Imaging (now Ricoh Imaging).

In 1975 Pentax created the Pentax K-mount (or PK-mount), a bayonet lens mount standard for SLR cameras. It was updated several times and was still used for their digital SLRs.
KAF2 and KAF lenses are best for the MZ cameras.

The Pentax MZ cameras (ZX in America) were a series of small and light 35mm film SLR cameras, made from 1996 (MZ-5/MZ-10) until 2006 (MZ-S). As most people switched to digital photography, MZ cameras are cheap. They are often sold with two or three lenses, which can make them a deal. The plastic gearing can fail over the time, everything else seems to be reliable. So rarely used cameras are to be preferred.


The model presented here, the MZ-50, was launched in 1997.

electronic vertical focal plane, speeds: 30s to 1/2000 and B

Last, but not least: an important accessory if you want to take long exposure night photos: a cap for the viewer. If light strikes the viewer, it might falsify the automatic exposure.

This is a decent, very light SLR camera with a good lenses that can be bought for cheap. A very good start if you want to get into real film cameras. It has several point-and-shoot modes if you want this, but can also be used very well in manual mode. A very nice find.

I bought these cameras because I wanted to know how they feel before ordering a modified Reflx Lab half frame MZ-50. The half frame model is here.
