The Exakta lens mount was introduced in 1936 with the Kine-Exakta model made by Ihagee. It would be used on most of the later Exakta models, as well as the Exa models until 1977.

The lens mount was also adopted by the Japanese manufacturer Tōkyō Kōgaku for the Topcon 35mm SLRs released from 1957 and sold until the end of the 1970s.

A huge number of lenses was produced in that mount, made by all sorts of manufacturers, but we can try to list some of them.

Angénieux

Here are the known types of finish:

  • type I: black with three chrome rings
  • type II:
  • 35/2.5 Type R1

Arco

See Arco lenses.

Berthiot

  • Olor 38/5.7, chrome, not a retrofocus design, manual diaphragm

Canon

According to Peter Dechert,[1] Canon made a pair of lenses in Exakta mount in 1955. As he points out, these lenses should not be confused with later lenses marked "EX" for an entirely different mount.

  • 100/3.5 EX
  • 135/3.5 EX

Corfield

Corfield seems to have sold some lenses in Exakta mount for their Periflex models with Exakta bayonet. These lenses were made by Enna.

  • 35/3.5 Retro-Lumax (Enna type I preset)
  • 135/3.5 Tele-Lumax (preset?)

A Vines Retro-Lumax 35/3.5 preset lens has been seen at ebay auction with Exakta mount. On the box there is a Vines Cameras logo, and the lens does not look like Enna lenses. A Vines Tele-Lumax 105/2.4 lens has also been reported in Exakta mount over a T2 mount.

Enna

Enna was a German independent optical company, that made most of their lenses in M42 mount. Some were sold under the Revue distributor name. Here are the known types of finish:

  • type I: chrome, preset or manual diaphragm
  • type II: black with knurled rings and wide chrome stripes, preset diaphragm
  • type II tele: black with wide chrome stripes, manual diaphragm
  • type III: black with many fine chrome stripes, auto diaphragm unless noted
  • type III tele: all black, crackled finish, except the base with chrome stripes, manual diaphragm unless noted
  • type IV: all black, auto diaphragm

The lenses are listed, with the types known to exist for sure:

  • 28/3.5 Ultra-Lithagon (I preset)
  • 35/4.5 Lithagon (I preset)
  • 35/3.5 Lithagon (II preset)
  • 35/2.5 Super-Lithagon (I preset)
  • 85/1.5 Ennalyt (I preset, III preset)
  • 135/2.8 Tele-Ennalyt (III preset)
  • 400/4.5 Tele-Ennalyt (III tele)
  • 85-250/4 Tele-Zoom (III tele preset)

Enna also made a range of sockel lenses. A socket base comprised the mount and focusing mechanism, and an interchangeable optical unit could be mounted on it. There were two generations of sockel lenses, one with semi-automatic diaphragm (manual cocking) and the other with fully auto diaphragm. The two generations were incompatible between them.

Lenses for the first sockel system (black with wide chrome stripes):

  • 28/3.5 Lithagon
  • 35/2.8 Lithagon
  • 50/1.9 Ennalyt
  • 135/3.5 Tele-Ennalyt
  • 240/4.5 Tele-Ennalyt

At the beginning, on the lenses sold on the US market, the name Lithagon and Ennalyt was replaced by Sandmar.

Lenses for the second sockel system (black with many thin chrome stripes):

  • 28/3.5 Lithagon, later Ennalyt
  • 35/2.8 Lithagon, later Ennalyt
  • 50/1.9 Ennalyt
  • 90/2.8 Tele-Ennalyt
  • 135/2.8 Tele-Ennalyt
  • 240/4.5 Tele-Ennalyt

Feinmess

The East German optical company Feinmess made one lens in Exakta mount, the 105/4.5 Bonotar, in alu finish with knurled rings. This lens also equipped some East German 6x9 folding cameras like the Belfoca. It is said about 4,000 were produced in Exakta mount (see here).

Isco

Isco was a succursal of Schneider, and made a lesser range of lenses. They made some in Exakta mount. Here are the known types of finish:

  • type I: all chrome, slim barrel manual diaphragm
  • type II: chrome, big knurled rings
  • type IIb: black with wide chrome stripes, big knurled rings, auto diaphragm
  • type III: all black, big knurled rings
  • type IV: shape of inverted cone, black with wide chrome stripes, auto diaphragm
  • type V: shape of inverted cone, all black, preset diaphragm

The lenses are listed, with the types known to exist for sure:

  • 24/4 Westrogon (IIb)
  • 180/2.8 Tele-Iscaron (V)

Kilfitt

Kilfitt lenses had a set of adapters, to attach them on various lens mounts. The only Kilfitt lens with a fixed Exakta mount was the 40mm Makro-Kilar.

  • 4cm f/3.5 Makro-Kilar D, chrome, s/n 211-XXXX
  • 4cm f/3.5 Makro-Kilar E, chrome, s/n 209-XXXX
  • 4cm f/2.8 Makro-Kilar D, chrome, then black, s/n 245-XXXX
  • 4cm f/2.8 Makro-Kilar E, chrome, then black, s/n 246-XXXX

The markings evolved from Kamerabau-Anstalt-Vaduz Kilfitt-Makro-Kilar to Heinz Kilfitt München Makro-Kilar to Kilfitt München Makro-Kilar.

Sankyō Kōki / Komura

Made by Sankyō Kōki

  • 105/2.8, black with wide chrome stripes, preset
  • 135/2.8, black with chrome mount, preset
  • 200/3.5, black, preset

Ludwig

  • 50/2.9 Meritar, chrome, slim barrel, then heavy barrel with knurled rings, then conical barrels with black stripes

Meyer

Meyer was the second East German provider of Exakta lenses, after Carl Zeiss Jena.

The main types of finish are listed by chronological order:

  • type 0: chrome or alu finish, slim barrel, manual diaphragm
  • type I: alu finish, knurled focusing ring, preset, semi auto (manual winding) or auto diaphragm
  • type pre-II: black with a chrome band and indentations around the focusing ring, auto diaphragm
  • type II: black with wide chrome stripes, preset or auto diaphragm
  • type III: black, slightly knurled focusing ring, some chrome on diaphragm ring, auto diaphragm
  • type Tele: alu or black finish, manual or preset diaphragm (tele lenses)
  • type Tele II: black with chrome stripes, preset diaphragm

Some lenses (type III) had internal auto diaphragm coupling, to use with the Exakta RTL 1000.

The lenses are listed, with the types known to exist for sure:

  • 29/2.8 Orestegon (III RTL)
  • 30/3.5 Lydith (II preset)
  • 35/4.5 Primagon (I preset)
  • 50/3.5 Primotar E (I semi auto)
  • 50/2.9 Trioplan (I preset)
  • 50/2.8 Domiplan (II auto)

  • 100/2.8 Trioplan (0, I preset, I auto pre-II)
  • 100/2.8 Orestor (II preset, III RTL)
  • 135/2.8 Orestor (II preset)
  • 150/5.5 Telemegor (0)
  • 180/5.5 Telemegor (0)
  • 180/3.5 Primotar (Tele chrome manual, Tele black preset)
  • 200/4 Orestegor (II preset)
  • 250/5.5 Telemegot (Tele chrome preset)
  • 300/4.5 Telemegor (Tele black preset)
  • 400/5.5 Telemegor (Tele black preset)

Olympus

The only lens made by Olympus in Exakta mount is the Zuiko 4cm f/3.5, of which three versions are known. It was probably the same as the lens of the Olympus 35.

The first version has an all-chrome brass barrel and a manual diaphragm. The aperture scale is directly engraved on the focus ring, and it seems that the front of the lens rotates when the focusing ring is turned. The marking on the front rim is Olympus Zuiko C. 1:3,5 f=4cm No.xxxxx, in white on a black background. Only one example has been seen so far.[2]

The second version is made of chromed brass and has a manual diaphragm too. The barrel is a little longer and the aperture scale is engraved on the aperture ring itself, moving along an index placed on the front part of the barrel; this surely indicates that the front part does not rotate when focusing. Various examples are known, all with a lens number in the 62xxx range.[3] At least some of them have MADE IN JAPAN under the lens barrel. The front and rear caps are all chrome, and the front cap is stamped with the OLYMPUS OIC logo. The leather case also has the same logo. This logo was used by the company from 1949 and was already abandoned by late 1953.

The third version has an aluminium barrel and a preset diaphragm. The marking is Olympus Zuiko F.C. 1:3,5 f=4cm No.xxxxx, where F.C. stands for Full Coated, indicating that all the lens elements are coated. Only two examples have been seen so far.[4]

The chronology of the three versions is unclear: the most plausible order is the one presented above, but at least one source says that the aluminium version predates the more common brass version, on the basis of the lens number and poorer finish.[5]
