The Contaflex series is a family of 35mmSingle-lens reflex cameras (SLR) equipped with a leaf shutter, produced by Zeiss Ikon in the 1950s and 1960s. The name was first used by Zeiss Ikon in 1935 for a 35mm Twin-lens reflex camera, the Contaflex TLR; for the earlier TLR, the -flex suffix referred to the integral reflex mirror for the viewfinder. The first SLR models, the Contaflex I and II (introduced in 1953) have fixed lenses, while the later models have interchangeable lenses; eventually the Contaflexes became a camera system with a wide variety of accessories.
The Mecaflex was presented at photokina 1951 and launched two years later as one of the first SLRs, fitted with a leaf shutter behind the removable lens and a waist-level viewfinder with a reflex mirror that swings out of the way during the film exposure. Compared to twin-lens reflex cameras, the SLR offered several advantages: photographer would be able to view the scene exactly through the same lens that would be used to expose the film, and only a single lens was required, reducing costs. The later Hasselblad500C, introduced in 1957, is a similar SLR design that uses leaf shutters; for the Hasselblad, each of its interchangeable lenses has a shutter.
The first Contaflex SLRs were introduced in 1953, following the general design of the Mecaflex using a Compur leaf shutter and reflex mirror, but the Contaflex cameras were equipped with an integral eye-level finder and a fixed lens. The advantages of using the leaf shutter are low manufacturing costs, compactness, quieter operation, and flash synchronization at all shutter speeds.[1]:193 However, using a leaf shutter in an SLR requires additional mechanical complications to cock the shutter and return the mirror after the shutter is released and the film is wound; these were seen more as a challenge than a drawback at Zeiss Ikon, but no Contaflex model ever got a rapid return mirror.
However, only a very limited range of interchangeable lenses became available. For the models I and II, having a fixed lens, only three add-on converters were offered using a slide-on adapter, but from models III and IV onwards interchangeable lenses from 35mm to 115mm focal length were provided; at the time regarded as quite sufficient, as most would only be used with the standard lens anyway.[1]:193
Three years later, during 1956, the Kodak Retina Reflex was launched, followed by the VoigtländerBessamatic and the Ultramatic. The market soon flourished with leaf-shuttered SLR cameras. These mechanically complex cameras required precision assembly and high quality materials. More often than not many camera makes suffered from reliability issues, while the few better ones performed well, selling in quantity.
The Contaflex I, launched in 1953, was equipped with a fixed Zeiss Tessar 45mm f/2.8 lens with front-cell focusing.[2] The earliest ContaflexI cameras had a Synchro-Compur shutter with the old scale of shutter speeds (1-2-5-10-25-50-100-250-500) and no self-timer, but very soon it adopted the new scale 1-2-4-8-15-30-60-125-250-500.[3]:17
The Contaflex II, introduced the following year, was the same camera with an uncoupled selenium meter added to one side of the front plate.[2]
For both the Teleskop 1.7× supplementary lens could be attached to the front of the fixed lens using an accessory carrier bracket; as the name suggests, this extended the focal length by 70% to approximately 75mm.[4] The same bracket could be used for the Steritar A attachment, which was used for stereo photography.[5]
The Contaflex III, launched in 1956, was the same as the I, but equipped with a Zeiss Tessar 50mm f/2.8 with unit helical focusing.[2][3]:21
The Contaflex IV, introduced the same year, was the same camera with the uncoupled meter inherited from the Contaflex II.[2]
The III and IV were equipped with a convertible lens system branded Pro-Tessar, where the front element of the standard lens was removable and could be replaced by supplementary lenses, as discussed in the section Contaflex lenses, to create 35mm and 80mm lenses, both f/4.[2]
Contaflex Alpha and Beta
The Contaflex Alpha and Contaflex Beta, both introduced in 1957, were lower-cost versions of the convertible-lens Contaflex III and IV, respectively; to reduce costs, the lens was changed to a Rodenstock (Zeiss-branded) Pantar 45mm f/2.8 triplet with front-element focusing[3]:13,21 and the Compur shutter was replaced by a Prontor Reflex shutter, with a slight reduction in minimum shutter speed to 1⁄300.[6]
The Alpha had no meter, like the I/III, and the Beta had the selenium meter of the II/IV.
The front element of the lens could be interchanged with supplemental lenses to create 30mm and 75mm lenses, both f/4. These supplemental lenses had been introduced and were shared with the earlier (1955) Contina III 35mm viewfinder camera.
Contaflex Rapid and Super

Overview
Production
1958–60 (Rapid)
1959–63 (Super)
The Contaflex Rapid was introduced in 1958; compared to the III, which it replaced, the Rapid had a slightly longer body, a built-in accessory shoe, a winding lever and a rewind crank. It retained the 50mm Tessar and convertible lens system from the III. The "Contaflex" name engraved on the front of the prism was changed to a script typeface instead of the sans-serif used on prior Contaflex cameras. It was the meterless version and was discontinued in 1960.[7]
The Contaflex Super, launched the following year, was based on the Rapid and had a coupled selenium exposure meter on the front side of the prism. It is easily recognized by the wheel on the front plate for the setting of the film speed (DIN). The meter needle was visible in the finder as well as on the top plate from the outside. It is sometimes referred to parenthetically as the Super (old style) to avoid confusion with the later Super (new).[8]
The major innovation for the Rapid/Super over the III/IV was the introduction of interchangeable film magazines, which permitted the photographer to swap emulsions mid-roll.[7] The new body of the Rapid and Super allowed them to take magazine backs, interchangeable with a partly exposed film inside. Magazine backs, rare among 35mm cameras, also were supplied for the Contarex of Zeiss Ikon.
The Rapid and Super (old style) could take the same supplementary 35mm f/4 and 80mm f/4 lenses as the III and IV, and newer Pro-Tessar supplementary lenses were available for the Rapid and Super to create 35mm f/3.2, 85mm f/3.2, and 115mm f/4 lenses.[8]

Prima
Overview
Production
1959 – 1965
The Contaflex Prima, launched in 1959 and sold until 1965, was based on the body of the Rapid, retaining the new film magazine and lever wind, but with costs reduced by fitting the Pantar triplet lens and the Prontor shutter like the Alpha and Beta. The Prima had a coupled exposure meter placed on the side of the front plate, similar to the Beta.[9]
The Prima could take the same Pantar supplementary lenses as the Alpha and Beta.
The Contaflex Super (new) and Contaflex Super B are very similar cameras. Both have a new body design, being longer with added bulk. The information about which came first is a bit contradictory in some reference books, but it seems the Super (new) was launched in 1962, introducing the new body design and a new selenium exposure meter in a prominent rectangle marked Zeiss Ikon in front of the prism. The aperture wheel was replaced by a more traditional aperture command, and the meter read-out was visible both on the exterior and in the finder.[10]
The Super B was launched in 1963, and added a shutter-priority automatic aperture, and some other small changes.[11] The Super B can be distinguished by the presence of an "A"utomatic setting for the shutter speed ring and an EV scale in the viewfinder.[1]:197
From the Super (new) and Super B, the Zeiss Tessar 50mm f:2.8 lens was recomputed and supposedly performed better.[1]:197 They could still take the same supplementary lenses, with one exception discussed in the relevant section.
Contaflex Super BC and S

Contaflex Super BC
Overview
Production
1965 (BC) / 1968 (S) – 1972
The Contaflex Super BC was introduced in 1965, and was a Super B with the selenium meter replaced by a CdS through-the-lens exposure meter. It still had a black rectangle marked Zeiss Ikon on the front of the prism, but it was only decorative. It had a battery compartment at the bottom front.[12]
The Contaflex S was the last variant, introduced in 1968, and was simply a renamed Super BC, sold until Zeiss Ikon ceased production in 1972. It had a black rectangle marked Contaflex S on the front, and a different, newer Zeiss Ikon logo. It proudly sported the word Automatic on the front of the shutter.[12]
The Super BC and S could take the magazine backs, as well as the usual supplementary lenses.
Both the Contaflex Super BC and S were, along with the 126-format Contaflex 126, available in chrome or black finish.
The Contaflex 126 is related to the Contaflex SLR family primarily by its name and general appearance, as it takes a different film format (126 film) and uses a different shutter technology (focal plane shutter) than the rest of the family. Voigtländer had developed it as the Icarex 126, and it was released as a Zeiss Ikon camera after Voigtländer's operations were consolidated into its larger parent in the late 1960s.[13] It was introduced in 1967 to accept Kodak 126 (Instamatic) cartridges. It was one of the very few SLRs taking 126 film, and one of the very few cameras using that film aimed at the premium market. Two other examples of 126 SLRs are the Rollei SL26 and Kodak Instamatic Reflex.
Former Zeiss-Ikon chief designer Hubert Nerwin, who designed the famous CONTAX 2 and 3 rangefinder cameras and other cameras for Zeiss-Ikon, later invented the 126 film cassette. This was after he emigrated to the U.S. after World War 2 and was working for Kodak.
The Contaflex 126 is an SLR with a focal-plane shutter and interchangeable lenses. It was available in chrome or black finish.
The range of lenses was:
Zeiss Distagon 25/4
Zeiss Distagon 32/2.8
Zeiss Color-Pantar 45/2.8, three-element, cheaper
Zeiss Tessar 45/2.8, four-element, better
Zeiss Sonnar 85/2.8
Zeiss Tele-Tessar 135/4
Zeiss Tele-Tessar 200/4
The Contaflex 126 lenses are often confused with other lenses by the sellers. They can only be used on the Contaflex 126 body, which can only accept the obsolete 126 film cartridge, so the value of these lenses is not very high, despite their famous names.
Weber SL75
When Zeiss Ikon stopped making cameras in 1972, they had prototypes in various stages of development. One of them was the SL725, which would be a successor to the Contaflex line with an electronic shutter. The prototype ended in the hands of a company named Weber, which presented the camera at a photokina show under the name Weber SL75, but could not afford to put it into production, and did not find a partner to do so. The lens mount was a modification of the Contarex camera lens mount. Carl Zeiss advertised a range of lenses for the Weber SL75, all with the T* multicoating:[14]
18/4 Distagon
25/2.8 Distagon
35/2.8 Distagon
50/1.4 Planar
85/2.8 Sonnar
135/2.8 Sonnar
200/3.5 Tele-Tessar
An eBay seller seems to have uncovered a small stock of the Planar lens, and has recently sold a couple of them.[15] Recently (2021), several of these lenses have surfaced again and were sold on eBay. No SL75 body seems to have surfaced so far, and the only picture found on the web is here and from an Italian photo magazine as a preview in their Nov. 1974 issue, as seen to the right.
Contaflex lenses
There are three classes of supplemental lenses available for Contaflex SLRs, which are not interchangeable between class:
The Contaflex I and II could only take the Teleskop 1.7x supplementary lenses, and the Alpha, Beta and Prima had their own limited range of Pantar supplementary lenses.
Contaflex SuperB+Zeiss 8x30B monocular
The models III, IV, Rapid, Super, Super (new), Super B, Super BC and S all have a Zeiss Tessar 50mm f:2.8 lens (27mm screw-in or 28.5mm push-on filters); the front element can be removed and replaced by a supplemental lens:[25]:190
Zeiss Pro-Tessar 35/4 (49mm filters), later replaced by the Pro-Tessar 35/3.2 (60mm screw-over filters)
Zeiss Pro-Tessar 85/4 (60mm screw-over filters), later replaced by the Pro-Tessar 85/3.2 (60mm filters)
Zeiss Pro-Tessar 115/4 (67mm filters)
Monocular 8x30B, equivalent to a 400mm lens (attaches to the 50mm f/2.8 Tessar lens).
There was also a Zeiss Pro-Tessar M 1:1 supplementary lens, that kept the focal length of 50mm but allowed 1:1 reproduction. The effective speed of the M 1:1 lens is f/5.6. The 50mm standard front elements, as well as the Pro-Tessar M 1:1 elements, were different between the early models III, IV, Rapid and Super with the old model of Tessar, and the later models Super (new), Super B, Super BC and S with the recomputed Tessar.[22] It appears that the mount was very slightly modified, and it seems physically impossible to mismatch the elements as the journal diameter above the bayonet mount had been reduced by approximately .006"
There were also stereo attachments:
Steritar A for the Contaflex I and II
Steritar B for the other Tessar-equipped models
Near Steritar for close up stereo pictures .2 – 2.5 meters
(Normally interchangeable with the older Tessar line of Steritar B camera lenses)
Zeiss Proxar for Contaflex: 1M,0.5M,0.3M,0.2M and 0.1M

Carl Zeiss AG, branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe and Otto Schott he laid the foundation for today's multinational company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s. ZEISS is active in four business segments with approximately equal revenue in almost 50 countries, has 30 production sites and around 25 development sites worldwide.
The Tessar is a photographic lens design conceived by the German physicist Dr. Paul Rudolph in 1902 while he worked at the Zeiss optical company and patented by Zeiss in Germany; the lens type is usually known as the ZeissTessar. Since its introduction, millions of Tessar and Tessar-derived lenses have been manufactured by Zeiss and other manufacturers, and are still produced as excellent intermediate aperture lenses.
Zorki is the name of a series of 35mm rangefinder cameras manufactured in the Soviet Union between 1948 and 1978.
Praktica was a brand of camera manufactured by Pentacon in Dresden in eastern Germany, within the GDR between 1949 and the German reunification in 1990. The firm Pentacon was divided in mainly two parts and sold after German reunification. Schneider Kreuznach and Noble bought parts of it. Pentacon is a Dresden-based company in the optical and precision engineering industry, which was at times a major manufacturer of photo cameras. The name Pentacon is derived on the one hand from the Contax brand of the Dresden Zeiss Ikon Kamerawerke and Pentagon, because a pentaprism for SLR cameras developed for the first time in Dresden has this shape in cross section. Today's PENTACON GmbH Foto- und Feinwerktechnik is still based in Dresden. It is part of the Schneider Group, Bad Kreuznach. Pentacon is the modern-day successor to Dresden camera firms such as Zeiss Ikon; for many years Dresden was the world's largest producer of cameras. Previous brands of the predecessor firms included Praktica, Exa, Pentacon, Zeiss Ikon, Contax, Ica, Ernemann, Exakta, Praktiflex, and many more.
Rolleiflex is the name of a long-running and diverse line of high-end cameras originally made by the German company Franke & Heidecke, and later Rollei-Werke.
Contax began as a German camera model in the Zeiss Ikon line in 1932, and later became a brand name. The early cameras were among the finest in the world, typically featuring high quality Zeiss interchangeable lenses. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Japanese multinational Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras. The rights to the brand are currently part of Carl Zeiss AG, but no Contax cameras are currently in production, and the brand is considered dormant.
The Rolleiflex SL35 is a range of SLR cameras manufactured and sold by the German camera maker Rollei from 1970 to 1982. This range of cameras uses 35mm film. The camera bodies were initially made in Germany. After Zeiss Ikon discontinued camera production, Rollei acquired the Voigtländer brand and camera designs in 1972, and began producing a second generation of SLR cameras in Singapore starting from 1976. Some of those second-generation cameras were rebranded and marketed as Voigtländer VSL.
The history of the single-lens reflex camera (SLR) begins with the use of a reflex mirror in a camera obscura described in 1676, but it took a long time for the design to succeed for photographic cameras. The first patent was granted in 1861, and the first cameras were produced in 1884, but while elegantly simple in concept, they were very complex in practice. One by one these complexities were overcome as optical and mechanical technology advanced, and in the 1960s the SLR camera became the preferred design for many high-end camera formats.
Retina was the brand-name of a long-running series of German-built Kodak 35mm cameras, produced from 1934 until 1969. Kodak Retina cameras were manufactured in Stuttgart-Wangen by the Kodak AG Dr. Nagel Werk which Kodak had acquired in December 1931.
Yashica Co., Ltd. was a Japanese manufacturer of cameras, lenses, and film editing equipment active from 1949 until 2005 when its then-owner, Kyocera, ceased production. It acquired the lens manufacturer Tomioka.
The Zeiss Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in 1929 and patented by Zeiss Ikon. It was notable for its relatively light weight, simple design and fast aperture.
The Tenax I is a 24x24 mm fixed lens camera by Zeiss Ikon launched in 1939.
The Bessamatic and Ultramatic were lines of 35mm SLR cameras made by Voigtländer in the 1960s, featuring a selenium meter. It uses a leaf shutter, similar to competing SLR cameras manufactured by Kodak and Zeiss Ikon in Germany, rather than the focal plane shutter almost universally adopted by Japanese SLRs such as the contemporary Nikon F and Pentax Spotmatic. The Ultramatic was released in 1963, which used the same lens mount and added a shutter-priority autoexposure mode.
The Topcon RE Super, or Beseler Topcon Super D in USA, was launched by Tokyo Kogaku KK in 1963 and manufactured until 1971, at which point it was upgraded to the Super D and again to Super DM the following year. General sale continued for several years. These later models have a shutter release lock lever on the shutter release collar. It is a professional oriented 35mm SLR camera that had a comprehensive range of accessories available. It has a removable pentaprism viewfinder and focusing screen. It features the Exakta bayonet lens mount for interchangeable lenses. A special accessory shoe is situated at the base of the rewind knob with a standard PC sync. contact next to it. The release button is placed at the right-hand camera front, but there is no mirror-up facility; this was included on the upgraded versions. The standard lens is the RE. Auto-Topcor 1:1.4 f=5.8cm or the slightly slower 1:1.8 version. A battery-operated winder could be attached to the camera base.
Contarex is a line of 35mm single lens reflex cameras (SLRs) made by Zeiss Ikon. It was first presented at Photokina in 1958 and initially scheduled for delivery in the spring of 1959, but it was not made generally available in the United States until March 1960. The first model is popularly known as the Contarex I, the Bullseye, or the Cyclops, after the prominent light meter window above the lens, in front of the pentaprism. The camera was aimed at the high-end and professional markets; in 1961, the retail price was $499.
Contarex lenses are a series of photographic camera lenses used by the Contarex camera, which use the Contarex bayonet lens mount. The first set of lenses were presented with the Contarex I at Photokina in 1958 and initially scheduled for delivery in the spring of 1959, but they were not made generally available in the United States until March 1960.
Icarex is a line of 35mm single lens reflex cameras (SLRs) made by Zeiss Ikon, derived from an earlier Bessaflex project developed by Voigtländer. The Icarex line, which included the Icarex 35, Icarex 35CS, Icarex 35S, and SL 706, was aimed at a mid-range market above the Contaflex SLR, which was intended for advanced amateurs, but below the Contarex line for professionals.
The Vitessa was a line of 35mm compact rangefinder cameras made by Voigtländer in the 1950s, equipped with leaf shutters, similar in concept to and marketed against the competing Kodak Retina cameras manufactured by Kodak. Most of the Vitessa cameras were fixed-lens models equipped with collapsable lenses for portability. One of the later Vitessa models, the Vitessa T (1956), introduced the Deckel (DKL) bayonet mount for interchangeable photographic lenses.
Prominent refers to two distinct lines of rangefinder cameras made by Voigtländer.
The Vito and Vitomatic, Vitoret, and Vito Automatic were several related lines of 35 mm compact viewfinder and rangefinder cameras made by Voigtländer from the 1940s through the early 1970s, equipped with leaf shutters, similar in concept to and marketed against the competing Kodak Retina cameras manufactured by Kodak. All of these cameras were fixed-lens models; the models in the Vito line identified with Roman numerals were equipped with folding mechanisms and collapsible lenses for portability, while the others were rigid, non-folding cameras.
