Contax was a camera brand, started in 1932, noted for its technical innovation and wide range of Zeiss lenses, known for their high optical quality. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras.

While the firm of Ernst Leitz of Wetzlar established the 24 mm × 36 mm negative format on perforated 35 mm movie film as a viable photographic system, Zeiss Ikon of Dresden decided to produce a competitor designed to be superior in every way. The name Contax was chosen after a poll among Zeiss employees. Dr. Ing. Heinz Küppenbender was its chief designer.
Made between 1932 and 1936, the original Contax, known as Contax I after later models were introduced, was markedly different from the corresponding Leica. Using a die-cast alloy body it housed a vertically travelling metal focal-plane shutter reminiscent of the one used in Contessa-Nettel cameras, made out of interlocking blackened brass slats somewhat like a roll-up garage door. This complex shutter became the characteristic of the Contax camera and its Super-Nettel derivative. By contrast, the competitive Leica followed the established design of using rubberized fabric shutter curtains wound around rollers, moving horizontally. The Contax design allowed a higher maximum shutter speed: the top speed was 1/1000s, then increased to 1/1250s in the Contax II. The fact the shutter ran across the shorter dimension of the format area was a significant factor for achieving this technical feat. The interlocking slats were aligned by specially woven silk ribbons, which were very strong but subject to wear. Replacing these ribbons was difficult but, contrary to modern cameras, made for a 400,000-cycle life. Zeiss also invented the System Camera, with all sorts of near-photo, wide-angle, mirror-house, long-focal-length lenses for specific situations. However Zeiss called it Universalkamera. One of the key design features was a coupled rangefinder with a very long baseline, with its own eyepiece next to that of the viewfinder. To enhance accuracy, a novel rotating wedge system was employed in lieu of the common swinging mirror mechanism. Other main features included focusing drive built into the camera body for use with standard lens, removable back, shutter-speed knob integral with film-wind knob placed at the front of the camera body, and black-enamelled finish.
The young lens designer Ludwig Bertele, formerly of Ernemann, was charged with the responsibility of designing the lenses. The greatest advantage of the Zeiss lenses was the reduced number of air-to-glass surfaces in Bertele's designs. In the years before lens coating was generally practiced, this had advantages for contrast and resistance to lens flare. Zeiss also pioneered glass coating, and before the war coated lenses were offered. After lens coating became universal post WW2, designers were given more freedom in using extra air-to-glass surfaces in correcting lens aberrations, without fear of the ill effects of surface reflections.
In 1936 the Contax II and III models were introduced; the only difference between them was the integral exposure meter on the latter model. They introduced the combined eyepiece for both viewfinder and rangefinder, the shutter speed and film wind knob placed on the top plate, fastest shutter speed at 1/1250 s. and finished in chrome plating. They became very popular among professional photographers, especially photojournalists who demanded high-performance, large-aperture lenses for available-light work and a workhorse. The vertical shutter had both variations in speed, slit and a break that was again a Zeiss first.
After the Second World War, a few Contax cameras were produced at the original Dresden factory, and some were assembled at the Carl Zeiss optical works at Jena, before production was transferred to Kiev in Ukraine. During the war years, the chief designer, Hubert Nerwin, tried to convert the Contax into a single-lens reflex camera but was hindered by the presence of the upper roller of the vertical focal-plane shutter. The postwar design chief Wilhelm Winzenberg started with a clean slate, which became the Contax S (Spiegelreflex), even though the "S" was not marked on the camera.
The Contax S can be said to be the camera that defined the configuration of the modern 35mm SLR camera. Not only did it introduce the M42 lens mount which became an industry standard, but it was also equipped with a horizontal focal-plane shutter, and also removed a major objection against the reflex camera by offering an unreversed, eye-level viewing image by employing a pentaprism. Introduced in 1949, the S was followed by numerous models including D, E, F, FB, FM and FBM. During that period, VEB Zeiss Ikon, as the firm became known, was gradually under pressure from the new Zeiss Ikon AG in the US zone, so the original Zeiss Ikon and Contax names and trademarks gradually disappeared and were replaced by the new name of Pentacon, which never really caught on. Finally, this camera line was abandoned.
Meanwhile in the US zone, the three main Zeiss concerns – Carl Zeiss Stiftung (Carl Zeiss Foundation), Carl Zeiss optical, and Zeiss Ikon – were reestablished. With Hubert Nerwin in charge as design chief, Zeiss Ikon produced heavily revised Contax models, the IIa and IIIa, at a new plant at Stuttgart, and they were made until 1962.
With the emergence of the Japanese camera industry, mainly a consequence of the US pressure on West Germany's Zeiss to cease collaboration with the East-German Zeiss, and also the lack of raw materials the former was enduring, it was in a way forced to form an alliance with a Japanese maker. Asahi, maker of the Pentax, was engaged first; and it went as far as Zeiss designing a common lens mount, which constituted a detour from Pentax's adoption of the Easter German M42 mount, named for many years as the "Pentax Mount" to avoid any accreditation to the Eastern Block, and which became the Pentax K-mount after the two firms parted company. An alliance was then formed with Yashica, and a new line of Contax single-lens reflex cameras was born, starting from the RTS of 1975. Numerous models followed, which also included compacts, medium-format reflex cameras, and digital cameras.
Interestingly, rival Leica in the 1970s and '80s used a couple of West German Zeiss-designed wide-angle lenses for their own cameras. The 15 mm Hologon was the first super-wide lens on a Leica, and the Leica reflex had access to the 15 mm Distagon lens as part of the Leitz supplied range.
Kyocera took over Yashica in 1983 and continued to manufacture products under the Yashica and Contax brands. In the mid-90s came their Contax G1 with outstanding lenses and a little later the G2, both fully manual or automatic, The first zoom lens to a RF camera, lenses from 16 mm to 90 mm. However, by 2002 the company's film camera products were declining in sales, and its newer digital camera products failed to make serious inroads into the digital-photographic market. In 2005, Kyocera discontinued all photographic equipment manufacture, including the Contax brand in 2005, thus bringing the Contax story to a close.
Original Contax rangefinder models
In contrast to the contemporary Leica which was evolved from its original concept into a photographic system, the Contax was designed as the heart of a photographic system from the start. A heavily engineered machine of tremendous complexity, it was Zeiss Ikon's showcase of the technology it possessed.
The Contax I had six identifiable variants, but fundamentally identical; every aspect was designed to be better than the Leica. For instance, the removable back was for faster loading and reloading, the bayonet lens mount was designed for rapid lens interchangeability, the long-base rangefinder was for more accurate focusing with large aperture lenses, and the vertical metal shutter not only gave a faster maximum speed but also banished the problem of shutter blinds burning.
However, its operation was something of an acquired taste, which explains the more conventional successors, the Contax II and III models. Not only was the combined shutter speed dial and film advance knob placed at the more conventional position, it became much easier and quicker to operate. The combined viewfinder and rangefinder was not the first one on the market, but it was the first on a system camera which offered significant operational advantage, a lead ahead of the Leica until the Leica M3 of 1954.
Since the Contax was produced at the Dresden works before the war, the new Zeiss Ikon firm in Stuttgart did not have the tools to recommence production. The resultant Contax IIa and IIIa models, while sharing many similarities with the prewar forebears, also showed significant simplification and cost-cutting by using cheaper materials, due to the lack of resources. However, these simplifications were also largely responsible for making them somewhat more reliable.
Designed to retain backward compatibility, the IIa and IIIa (introduced in 1950 and 1951 respectively) used the same lens mount as the prewar models, but due to the smaller dark chamber inside the lens throat, the pre-war Biogon 35/2.8 wide-angle lens could not be fitted.
Contax IIa and IIIa
The Zeiss Ikon Model 563/24 was a complete redesign of the previous II/III cameras, and was sold by Zeiss Ikon from 1950 to 1961. Gone were the troublesome silk shutter straps; in their place were straps made of nylon; a flash synch was added; and the body's size and weight were reduced. Shutters were still guaranteed for 400,000 cycles. The same internal/external bayonet mount was kept. This line was an engineering and manufacturing tour de force, and is considered by many to be the finest camera ever made[by whom?]. As with the II and III, the IIa was the base camera, and the IIIa had an added exposure meter attached on top of the camera. The shutter lammels were changed to duraluminium, lighter and faster to start and stop; however, they were thicker, too. The old Biogon did not fit, so a new one was designed together with the new Biogon 21 mm f 4, same as the famous 38 mm i Hasselblad SWC, gave new perspectives to wide angle photographing. The superwide 15 mm was built in a special camera body. Two basic variations of the IIa/IIIa were made: the so-called "black dial" and "color dial" cameras. The black dial cameras used a special flash synch cord for either flash bulbs or strobe flash. On the color dial cameras the ability to use the flash bulbs was eliminated; a P/C connector was added, and strobe synchronization was the only option. Where the Leicas of the day had only electronic flash synch at 1/25 second shutter speed, the Contax IIa/IIIa was synched at 1/50 and all slower speeds. On the later color dial cameras, the 1/50 marking on the shutter speed dial was painted chromate yellow, while the speeds of T, B, 1, 2, 5, 10, and 25 were black, and 100, 250, 500, and 1250 red.
The Contax IIa/IIIa ceased production in 1960 and was removed from the company catalog in 1961, replaced by the Contarex SLR. Ed Shoeneker, the owner of Hollywood Camera in Portland, Oregon from 1947 to the present, and a Zeiss dealer, described it thus: "We could not keep the Contax bodies and lenses on the shelf, people were buying all they could afford, and putting things they couldn't afford on lay-away. Then the new catalog came out, and the Contax was gone. No explanation at all. We were in shock. The camera that replaced it (the Contarex SLR) was a fine camera, but it cost so much more money, it never made the inroads into the market the Contax did, then we had to stop carrying the Contarex because they were too much money."
There is a demand for good working examples of the IIa/IIIa by collectors and users alike. As user cameras, they are highly versatile, compact, easy to handle, and give many years of trouble-free service. The range of lenses made over the very long period of time the lens mount was in use, adds to the usefulness of this design.
Dresden-built Contax SLR models
The loss of the Contax production tools at the Dresden factories turned out to be a blessing, as it prevented the use of the existing toolings and parts. The new design chief Wilhelm Winzenberg was not involved in the camera side of Zeiss-Ikon, this also allowed a brand-new Contax design to be developed, to follow Hubert Nerwin's wartime plan to make a Contax SLR camera.
As the traditional vertical-run Contax shutter required considerable space both above and below the film gate for the drum rollers, the upper roller takes up the critical space required for the reflex housing mechanism, making it dimensionally impossible to use it for a satisfactory SLR camera. Winzenberg solved the problem by the use of a completely new horizontal-run focal-plane shutter, thus allowing space for the reflex housing.
While the 35 mm SLR camera had already appeared before the war, its major disadvantage was the waist-level finder which gave a laterally reversed image, taking away the immediacy between the photographer and his subject. In the Contax reflex, to be called the Contax S, a pentaprism was positioned directly above the focusing screen, which offered an eye-level, unreversed view of the viewfinder. This major technical advantage was critical in establishing the 35 mm SLR as the definitive camera type for the decades that followed.
Since a larger lens mount would be desirable, the Contax S adopted a screw mount of M42X1mm specification, which was to become the de facto industry standard.
When introduced in 1949, the Contax S was not marked as such, only "Contax", but increasing pressure from the new Zeiss Ikon company in Stuttgart induced Zeiss Ikon in Dresden to progressively abandon the use of the established trademark and names. The following model, known as "Contax D", first appeared with a little "D" marked under the Zeiss Ikon logo to signify its source as Dresden, but that was not good enough: in some markets it was sold as "Pentacon", a name contrived from "Pentaprism" and "Contax". The name "Pentax" had been thought of before but, as with Germany's capitulation in 1945 all German patents and trademarks were declared void, the Japanese seized it and registered it. Subsequent models were also made wearing both Contax and Pentacon nameplates, the former were meant for markets where Zeiss Ikon Dresden still held the rights to its name. Eventually, the company went on to form the Pentacon VEB conglomerate (which included companies as Meyer-Optik Görlitz, Ihagee Dresden, and KW, among others) that would start the long line of Praktica cameras, high quality but affordable, in accordance with the Communist ideal. In all, 22 Contax/Pentacon models were built in Dresden.
Yashica/Kyocera-built CONTAX models
35 mm SLR models
The CONTAX name was revived in 1975 (noted officially it was named 'CONTAX' by Yashica/Kyocera, instead of 'Contax') after the production of the Contax rangefinder cameras ended in Stuttgart more than a decade before. Like the first attempt at forging an alliance with Pentax, Zeiss designed a new common lens mount, known as CONTAX/Yashica mount (C/Y) to be used on cameras bearing both marques. The first model, the RTS (short for "Real Time System"), was designed by Prof. Dr. Katsuiko Sugaya, styled by the Porsche Design studio, and manufactured by Yashica as Top Secret Project 130. Utilizing electronics comprehensively, it was the beginning of the new CONTAX line of SLR cameras which brought 13 different models, with the exception of the S2 and S2b (named after the original Dresden-built camera) being fully mechanical. The following is a brief rundown of the major models:
|RTS||1974||professional quality SLR with fixed pentaprism and electronically controlled shutter|
|139 Q||1979||aperture priority, TTL and TTL flash metering, X-synch 1/100|
|137 MD||1980||aperture priority, motor film transport (2-3 frame/s)|
|RTS II||1982||TTL flash metering, titanium shutter|
|137 MA||1981||aperture priority and manual modes|
|159 MM||1984||program and aperture priority modes, 1/4000 sec, X-sync 1/250 sec, improved MM bayonet mount|
|167 MT||1986||program, shutter and aperture priority, and manual modes, spot metering, permanent AE-lock, automatic bracketing|
|RTS III||1990||pre-flash TTL spot metering, ceramic vacuum film pressure plate, 100% viewfinder|
|ST||1992||1/6000 sec, X-synch 1/200, center weighted or spot metering|
|S2||1992||1/4000 sec mechanical shutter, spot metering, no TTL flash metering|
|S2b||1994||1/4000 sec mechanical shutter, center weighted metering, no TTL flash metering|
|RX||1994||focus assist system|
|AX||1996||autofocus with moving film plane|
|RX II||2002||simpler version of the RX (without focus assistance)|
Some special models were also made, for example
- CONTAX RTS Fundus - usually marked 'Medical/Scientific' on the base plate it featured a 3mm high guard around the shutter release and a lock button on the front plate for the shutter speed dial. Several of these also had enhanced mirror dampers; most RTS Fundus cameras were sold for laboratory use, especially with Zeiss ophthalmic equipment.
- CONTAX Preview – a non-metered body with the mechanical shutter from the Yashica FX-3, a Polaroid Back and a Right-Angle Finder to correct the reversed image.
- CONTAX CGCM – a severely stripped down 137MD used by the Swedish military and for recording images from oscilloscopes and similar screens.
- CONTAX Preview II – an upgraded and faster mechanical shutter than the Preview; it used the shutter found in the S2/S2b.
Some additional information
- CONTAX AX – This had a unique autofocus system that worked with manual focus lenses by moving the film plane inside the camera. A side benefit of this arrangement is that it allowed the AX to feature a macro mode which worked much like a built-in 10 mm extension tube, allowing for a magnification ratio higher than 1:1 without the use of bellows or extension tubes. By using of a special adaptor made by Kyocera, Hasselblad V-series lenses could also be used on all CONTAX C/Y mount cameras. Thus users could perform auto-focus of Hasselblad V-series lenses with AX.
- The S2 and S2b were deliberately designed without exposure automation, and only required a battery for the light metering system. The S2 had a spot meter, and was popular with some Zone System photographers, while the S2b had a centerweighted meter favored by some photojournalists.
The G Series was a unique 35 mm autofocus rangefinder system with interchangeable lenses. Rather than displaying a typical rangefinder focusing patch and brightlines, the first G1 had a zooming viewfinder with a focus confirmation light activated by the autofocus system if manual focus was required. The actual AF system, unlike AF for SLR cameras, used a twin-window rangefinder, but the alignment determination was electronic.
The G2 was the second camera body in the series, and displayed manual focus distance directly on a viewfinder LCD. The G2 was generally considered more rugged and controllable than the earlier G1. Another improvement over the G1 was its full parallax correction viewfinder. A limited edition run of black G2 bodies and lenses were produced, differing from the standard titanium finish found on the original G1 and G2.
The lenses used optical formulae not often used by Zeiss, which had specialized in SLR photographic lenses for many decades prior to the G Series. (These formulae appear to be repeated in the later Zeiss Ikon M-mount rangerfinder cameras.) The G series also boasted the only true zoom available for a rangefinder system, made possible by the electronic coupling of the camera's viewfinder and the lens.
CONTAX T-series compact cameras
Kyocera introduced a series of highly successful T-series compact cameras, offering Zeiss-designed lenses which appealed to photographers desiring high quality optics in a compact form.
- CONTAX T, a compact titanium body rangefinder camera in the style of Minox GT-E, with a five element Sonnar T* 38/2.8 lens
- CONTAX T2, a titanium body autofocus compact camera, featured a retracting 5-element Sonnar T* 38/2.8 lens, made in silver titanium, in black and gold plated finish
- CONTAX T3, smaller than CONTAX T2, with recomputed 6-element Sonnar T* 35/2.8 lens
- CONTAX T-VS and T-VS II, compact cameras with zoom lens (Vario-Sonar)
- CONTAX T-VS III, with CONTAX T style front door cover.
- CONTAX Tix, an APS CONTAX camera.
CONTAX compact digital cameras
- CONTAX T-VS digital, the digital version of T-VS III with a Carl Zeiss Vario Sonnar T✻ 2,8–4,8/7,3–21,9 mm and 5 megapixel CCD sensor
- CONTAX i4R, the smallest compact CONTAX
- CONTAX U4R and later on SL300R T✻, compact cameras with a Carl Zeiss Vario Tessar zoom and a rotating screen. Although very compact and simple to use, the SL300RT✻ featured some manual settings including metering and focus lock
A departure from the 35 mm format, the CONTAX 645 was an autofocus medium format SLR system, featuring an array of Zeiss lenses and interchangeable film and digital backs. One of its unique features was a film back equipped with the vacuum system originally developed for the 35 mm RTSIII SLR, which was claimed to increase sharpness by keeping the film perfectly flat in the plane of focus. By using the adaptor 'MAM-1' produced by CONTAX, Hasselblad V-series lenses including C, CF, CFE, CFI, F and FE can be mounted on CONTAX 645 as well.
In addition to 120 and 220 medium format backs with film inserts for quick loading, including the previously mentioned vacuum back, as well as a Polaroid/instant film back, many manufacturers offer a variety of interchangeable digital backs for the CONTAX 645 system:
- Phase One
The CONTAX N-series was an autofocus 35 mm SLR system, based around an entirely new electronic bayonet mount that was not compatible with previous CONTAX C/Y mount lenses. Three models were made: the N1, the NX and the N Digital, an early full-frame digital SLR.
The N Digital was one of the very first digital cameras to feature a full-frame 24×36 mm CCD sensor. The CONTAX NX was the prosumer 35mm model for advanced-amateur protographers, while the N1 was aimed at professional users. The series was made in Japan by Kyocera.
The N-series bodies used new N-mount lenses made by Kyocera, with electronically controlled aperture and autofocus. Nine lenses were produced for the mount, a mixture of primes and zooms. CONTAX did sell an adapter (NAM-1) allowing lenses from their 645 medium format system to be used on N bodies.
Electronic flash units
Not all CONTAX flash units are compatible with all cameras. There are essentially three groups of flash guns; those made for the G system, those made for the early (Yashica made) SLRs and those for the later (Kyocera made) SLRs.
Flash units available included (GNs stated at ISO 100):
- TLA20 (GN 20)
- TLA30 (GN 30)
- TLA140 (GN 14) – Very compact unit originally designed for the G1
- TLA200 (GN 20) – Compact flash unit originally designed for the G Series.
- TLA280 (GN 28)
- TLA360 (GN 36) – Best used with optional PS-220 Power Pack Set for faster recycling.
- TLA480 (GN 48) – Bracket-mounted flash system requiring external Power Pack PS-120 for operation. Also available, though very rare, is a PS-130 TLA AC Power Unit (AC 100v 50/60Hz) for studio use.
- RTF540 (GN 40) – Bracket-mounted system with slaves, coloured panels, AC Power Unit, High Voltage Battery and standard Power Pack sets. There was a late modification to the RTF540 that changed its capability to include TLA functionality for use with later cameras, via the RTF540 TLA Adapter; this was the RTF540T and could be recognized by the addition of a symbol - the letter T in a circle - to the serial number plate beneath the flash head.
Metz SCA adapters:
- SCA382 – Worked with the older cameras, but did not transmit ASA and aperture information on the Contax 645, Aria, RX, AX N1, NX, and N digital cameras.
Contax interchangeable lenses
Originally designed to be a system camera, many lenses were made for the original Contax, and this tradition carried on for all models with interchangeable lenses.
Lenses for the original Contax rangefinder models
Traditionally, lens makers like to mark the location of the company conspicuously on their lenses. Therefore, from the beginning of lens manufacture up to the end of the Second World War, all Zeiss lenses were marked "Carl Zeiss Jena". Since the new Oberkochen-based Carl Zeiss Optical company is not in Jena, its products are simply marked "Carl Zeiss", while the original factory carried on using the "Carl Zeiss Jena" marking. For the first few years Carl Zeiss of Oberkochen used the "Zeiss-Opton" marking.
The original series of lenses for Contax were mainly new designs by Ludwig Bertele, under the Sonnar name which was previously used by Contessa-Nettel. These lenses were mainly advanced Cooke triplet derivatives of markedly asymmetrical designs, for the purpose of maintaining maximum image contrast by reducing lens flare before the era of anti-reflective surface coating, many of them also offering large maximum apertures as well. Apart from these, some existing designs were also adapted for use too.
The Contax I lenses were finished mainly in black, and offered in a wide range of focal lengths. These included the following:
- Tessar 28/8 (non-rangefinder coupled)
- Biogon 35/2.8 (by Ludwig Bertele)
- Biotar 40/2.8
- Tessar 50/3.5
- Tessar 50/2.8
- Sonnar 50/2 (1931 by Ludwig Bertele)
- Sonnar 50/1.5 (1932 by Ludwig Bertele)
- Sonnar 85/2 (1932/33 by Ludwig Bertele)
- Triotar 85/4
- Sonnar 135/4 (1932/33 by Ludwig Bertele)
- Tele-Tessar 180/6.3
- Sonnar 180/2.8 (1936 by Ludwig Bertele), also called "Olympia-Sonnar"
- Tele-Tessar 300/8
- Sonnar 300/4
- Fernobjektiv 500/8
The most important[clarification needed] lens for the Contax II and Contax III was the 180/2.8 Sonnar, designed for Sports photographers covering the 1936 Berlin Olympics allowing fast speed, and the longest lenses also reached a focal length of 30cm and 50 cm, delivered with their own mirror housing.
During the war CZ made som special Military lenses like Sonnar 1.5/9 cm, 1,5/40 cm, still very rare constructions. Kriegsmarine and Luftwaffe demanded CZ and CZ lenses for their Leicas and Robots too.
While Jena continued to make some lenses for the pre-war Contax for a few years, lenses were also made for the Stuttgart-built post-war models, some were of new designs:
- Biometar 35/2.8
- Biotar 75/1.5
- Sonnar 300/4
- Tele-Tessar 500/8
Apart from refining existing designs, Carl Zeiss of Oberkochen also designed new lenses for the post-war Contax too:
- Biogon 21/4 (1951 by Ludwig Bertele, now working at Wild Heerbrugg, Switzerland, for Zeiss)
- Topogon 25/4
- Biogon 35/2,8 had to be redone to fit into the new IIa and IIIa cameras (Smaller dark room due to thicker dural lamells in shutter)
- Planar 35/3.5
- Tessar 115/3.5
Lenses for the Dresden-built SLR models
Lenses for the Dresden-built Contax single-lens reflex cameras used the M42X1mm screw mount, but as existing designs intruded too far into the camera body, making the swivelling mirror unable to clear the back of the lenses, a new series of lenses were made by Carl Zeiss of Jena, and later on, Hugo Meyer of Görlitz was also engaged as the second official supplier of original lenses. The following is a list of lenses made by Carl Zeiss:
- Tessar 40/4.5
- Tessar 50/3.5
- Biotar 58/2
- Biotar 75/1.5
- Triotar 135/4
- Sonnar 180/2.8
- Sonnar 300/4
- Fernobjektiv 500/8
Lenses for Yashica/Kyocera-built SLR models
The Yashica/Kyocera-built CONTAX cameras employed a new family of lenses. The names of these lenses generally reflect the designs and functions:
- Distagon : wide-angle retrofocus lenses.
- F-Distagon : fish-eye lenses.
- PC-Distagon : wide-angle lenses with shift feature for correcting perspective convergence.
- Hologon and Biogon : non-retrofocus wide-angle lens designs.
- Planar : fixed focal length primes of very large maximum aperture that range from medium wide-angles to short telephotos.
- Sonnar and Tele-Tessar : telephoto lenses, and Tele-Apotessar and Aposonnar indicated apochromatic correction.
- Vario-Sonnar : zooms lenses.
- Makro-Sonnar and Makro-Planar : macro lenses for extreme close-up work, based on the Sonnar and Planar designs.
- Tessar : 4-element lenses of medium focal length, sometimes referred to as a "Normal" lens.
- Mutar : teleconverters.
- Mirotar : mirror lenses.
Most of these lenses were marked T✻ referring to their T✻ coating (pronounced "Tee Star"), a highly developed Zeiss multi-coating process. The 'T' came from a German word 'Tarnung', which means 'camouflaging', as in making invisible, used here in reference to making flare invisible.
While these lenses were designed by Zeiss and manufacture shared between Zeiss and Yashica's optical division Tomioka, Zeiss increasingly allowed Tomioka to take responsibility of their manufacture.
Lenses for CONTAX SLR models
These cameras used the "C/Y" lens mount, short for "CONTAX/Yashica": Yashica being the lower-end consumer brand SLR system made by Yashica/Kyocera that shared its lens mount with CONTAX SLRs. Zeiss lenses in the C/Y mount came in either AE or MM varieties. MM lenses were more recent, with a setting that allowed the camera to select the aperture as part of its autoexposure system, while the older AE lenses did not. There was often no difference between an older AE and a newer MM lens apart from this feature. Sometimes, the older AE lens may be worth more on the used market because it may be a Germany-made example, while the newer lens may be Japan-made, despite their optical formula and build quality being identical.
In addition, with the use of an optional adaptor (special ordered from Kyocera), Hasselblad V-series lenses including C, CF, CFE, CFI, F and FE can also be used on CONTAX C/Y mount cameras.
- Distagon T* 15/3.5 - Superwide lenses. This model had also been ordered by both Leitz and Nikon and was adapted to be used on their own SLR cameras.
- F-Distagon T* 16/2.8 - Fisheye lens.
- Distagon T* 18/4
- Distagon T* 21/2.8 – Noted for its unusual design and sharpness.
- PC-ApoDistagon T* 25/1.4 - Prototype only.
- Distagon T* 25/2.8 - The nitial production was a failure due to mage softness, not just wide open, and Zeiss discreetly and successfully re-engineered the lens and it remains highly sought after.
- Distagon T* 28/2 – Noted for its lack of distortion. Nicknamed the "Hollywood" due to popularity for adaptation to movie cameras.
- Distagon T* 28/2.8
- Vario-Sonnar T* 28-70/3.5-4.5
- Vario-Sonnar T* 28-85/3.3-4
- Distagon T* 35/1.4
- Distagon T* 35/2.8
- PC-Distagon T* 35/2.8 – Noted for its shift capabilities.
- Vario-Sonnar T* 35-70/3.4
