Zenit (camera)
Zenit is a Soviet camera brand manufactured by KMZ in the town of Krasnogorsk near Moscow since 1952 and by BelOMO in Belarus since the 1970s. The Zenit trademark is associated with 35 mm SLR cameras. Among related brands are Zorki for 35 mm rangefinder cameras, Moskva and Iskra for medium-format folding cameras and Horizon for panoramic cameras. In the 1960s and 1970s, they were exported by Mashpriborintorg to 74 countries.
The name is sometimes spelled Zenith in English, such as the manuals published by the UK Zenit-importer TOE. However, TOE's imported camera bodies as from 1963 retained the "Zenit" badges. The early Zorki-based models before that time were labelled "Zenith" in a handwritten style of script.
History
Early years
The above Zenit was based on the Zorki rangefinder camera. In transforming the Zorki into an SLR, the simplest approach was taken: the rangefinder housing was removed from the top and replaced by a plain ground-glass screen and prism; a mirror was added below with a lever operated mirror setting system and the M39×1 thread mount was pushed forward to make room for the mirror inside.During the first years of production Zenit camera development coincided with that of the Zorki cameras. The Zenit-S had PC-synchro for external flash units and the Zenit-3M also had an RF-sibling, the Zorki-6. For an SLR, the Pentaprism of all classical Zenits was undersize, with the viewfinder showing about two-thirds of the actual frame-size. On the Zenit-S the mirror setting lever mechanism of the original Zenit was replaced by a cord and pulley system.
Zenit-E and its successors
During 1967 through 1969 KMZ built an automatic die-cast moulding line, allowing mass camera production. Camera production switched to the M42×1 thread and an instant-return mirror was also developed. This led to one of the most famous Zenits — Zenit-E which saw over 12 million produced. A heavy and tough camera which gained a reputation of being ‘bomb proof’, with a mechanism that was of exceedingly simple design along the lines of "what isn't there, can't go wrong". Automatic diaphragm functionality was not available until the introduction of the Zenit-EM, which used a direct mechanism linking the shutter release button to the aperture mechanism, significantly increasing the effort required to release the shutter. Production included both M39×1 and M42×1 mounts for the Zenit E and Zenit B models. Later models were only produced in the M42×1 with the Pentax K mount available for the latest models.Towards the end of the 20th century, the Zenit-E heritage became an obstacle to the development of more modern Zenit models. This was because almost all low-end Zenits until the recent 412DX have been based on the Zenit-E die-cast chassis, complying with the local philosophy that a crude but affordable camera was better than no camera.
The major events of the further development of Zenit-E line was:
- Introduction of an automatic 'jumping' diaphragm on the Zenit-EM
- TTL metering system on the Zenit-TTL
- Switching to the Pentax K mount — Zenit-122K
- DX-code introduction — Zenit-412DX
Advanced models
The first attempt to make high-end professional camera by KMZ was the Start in 1958. This camera had a full set of shutter speeds, a lens with an automatic diaphragm in a unique breech-lock mount, and even a knife for cutting-off part of the unexposed film. The photographer could choose between a pentaprism and waist-level finders. The grave disadvantage of the Start is blamed on lack of lenses; only one lens was ever made for the proprietary Start mount directly.With the success of the Zeiss-Ikon Contaflex of the mid-1950s and its follow-ups in form of the Bessamatic, Retina- and Paxette-reflex, Zenit's next attempt was the Zenit-4, -5 and -6 cameras. These were based on a Voigtländer Bessamatic-type mount with Compur-type iris-shutter near the lens elements. The poor durability and high manufacturing cost of this concept in contrast to the classical barebone Zenit design based on ultimate simplicity showed KMZ to have taken a wrong track: Nevertheless, the Zenit-5 was the first electric motor-driven SLR camera in the world, and the first Soviet zoom lens featured in the Zenit-6.
Following this, there were two more attempts to make high-end photographic equipment, namely the Zenit-7 and Zenit-D. Both were based on the completely new cloth-curtain shutter construction. The Zenit-D had automatic exposure mode. Its shutter was sped up to achieve X-sync at 1/125. Each of these had its own bayonet mount which helped to utilize the camera's most advanced features. There were plans to develop a full line of optics for these cameras but the new shutter was too complicated and unreliable. Production was cancelled shortly after, and the only lens made for new mounts were the standard types. The Start, Zenit-7 and Zenit-D utilized the same normal lens — a Helios-44 2/58. The Zenit-D is one of the rarest Zenit cameras — only 63 cameras were produced.
The Zenit 12-XP With its Helios f2/58mm lens and cloth shutter was widely sold by US Eastern camera stores. Many with the Zenit name covered with their "USA" brand. This Metallic re-badge was easy enough to gently pry off to see the true name Zenit. The TTL meter was fairly accurate and took decent shots. The 1981 price was $110 usa. The Russians believed that 58mm more closely matched the Human normal range than the standard 50mm used worldwide as a normal lens. It also had a T setting for timed exposures making it a good choice for yearly fireworks displays. The "T" setting locked the shutter open allowing a tripod mounted camera to be used with an index card to manually open for few bursts of fire works and then close and reset.
After one more unsuccessful camera which was produced in very small quantities, in 1979 production of the Zenit-19 began. This was a camera with an original electromagnet-driven focal-plane shutter, M42 lens mount, and shutter speeds from 1 sec to 1/1000. X-sync at 1/60 or 1/125. The camera has only manual shooting mode. The Zenit-19 was, perhaps, the top-of-the-line Soviet M42 lens mount camera.
Pentax-K mount series
In 1984 the Zenit-automat entered production. This had a Pentax K mount and a focal shutter with horizontal-travel cloth curtains. The only operation mode was aperture-priority. The camera was modified in 1988, to include shutter FZL-84 with vertical-travel metal curtains, and was reissued as the Zenit-AM. The Zenit-AM2 was a cheaper version of the AM without the self-timer.Next in line was the Zenit-APK. Its distinguishing feature was the introduction of a manual shutter mode in addition to aperture-priority. The original FZL-84 shutter was also changed to a licensed 'Copal Square' shutter.
The most recent model is the Zenit-KM of 2001. This is the second microprocessor-controlled camera in the Zenit range, and the second motor-driven SLR camera built by KMZ. Shutter speeds range from 1/2000 to 1 sec. X-sync is 1/125 sec, and the camera includes both manual shutter and aperture-priority modes as well as DX-coding from 50 to 3200 ISO. In 2004, the KM received some improvements and was renamed to the Zenit-KM Plus
The Zenit-KM Plus was the final Zenit camera to be produced; all SLR camera production at the Krasnogorsk factory ceased. These highly interesting ultimate Zeniths would have been major sellers on Western markets during the "SLR-decade" of the 1970s. However, they appeared at a time when their market-segment was saturated with second-hand equipment, so no major importer looked at them. One of the characteristics of Soviet camera manufacture was that the capability of its designers was well ahead of that of its policy-makers. The 20-year overdue replacement of the external selenium cell of the Zenit E by TTL-metering is said to be the work of an employee who made a conversion on his own accord.
Soviet Export Policy
In the West, the success of the Zenit line can be focused on the United Kingdom, primarily due to the marketing activity and service of TOE, and secondly the originally heavy UK tax-load of up to two-thirds on imported precision cameras.Substantial quantities were later sold by German discounters like Foto-Quelle and Neckermann. The main criticism of the USSR exporters at the time was that they could only supply hopelessly outdated equipment like the Zenit E that they had been directed to produce in quantity, despite having the capacity to produce more technically advanced products that might have been attractive to Western buyers. TOE were fighting a constant battle with their USSR-suppliers in this direction, having to fill the gap left by the excellent but not-for-export Soviet lenses which would have been a major selling-point, by a hodge-podge selection of second-rate mass-market optics from Japan, albeit under the "Helios" label.
