The 39mm screw mount — also called Leica Thread Mount (LTM ), Leica Screw Mount (LSM), or (incorrectly) M39 (as it is not a metric thread) — was introduced by Leica with the model I (C), and used on all the Leica models until the IIIg. The mount was adopted on many Leica copies and other 35mm rangefinder cameras.

39mm screw mount lenses were also made for the early Zenit SLRs, which have a different film to flange distance (rangefinder lenses mounted on these cameras will not focus to infinity).

Description Edit

The Leica mount is precisely M39 × 1/26" — i.e. 39mm diameter and 26 threads per inch — with 28.8mm film-to-flange distance and rangefinder coupling. Very early Canon (J mount) used an incompatible M39 × 1/24" screw mount, 39mm in diameter but with 24 threads per inch.[1] (It has been said that early Russian cameras used "M39 × 1", with 1 mm thread, but no conclusive evidence has been provided so far.)[2]

The film-to-flange distance was not standardized on very early Leica (until 1931)[3] and early Fed and Zorki (until the early postwar years).[4] These cameras were individually matched to their lenses, by way of shims, and this may cause compatibility problems.

The most important rangefinder camera bodies using the Leica screw mount are:

Some manufacturers made cameras and lenses with a 39mm screw mount completely incompatible with the Leica one, because of the different film-to-flange distance. Three such systems are:

(Further, screwmount lenses by Meopta may at first appear to be for the Leica; however, these have 38mm screw thread and are instead for the Meopta Opema.)

List Edit

We will attempt to make a list of 39mm screw lenses. These are arranged alphabetically by company name, or by brand name when the manufacturer is unknown.

All the lenses in this list are genuine Leica mount lenses, or at least were advertised as such by reputable dealers. Today some merchants convert old and rare lenses into Leica mount. Please do not include these converted lenses in the list.

Angénieux Edit

Arco Edit

See the main article on Arco lenses.

  • Colinar 8.5cm f/2
  • Colinar 13.5cm f/3.8
  • Tele-Colinar 13.5cm f/3.8
  • Tele-Snowva 13.5 cm f/3.8

Askania Edit

An incredibly long Fern-Achromat TE-N/PL 16/925mm f/16 has been sold by Auction Breker Köln on 01/10/2005. It was mounted on a reflex housing looking like the Astro Identoskop. A table engraved indicated the other lenses:

  • TE-N/PL 16/925mm
  • EX-T 22/1250mm
  • EX-T/PL 32/2000mm

Probably for military use only.

Astro Berlin Edit

Astro Berlin seems to have made some lenses with a genuine Leica mount. Today, many sellers are adapting Astro lenses to the Leica mount, often assembling them with the rear barrel of a 50/3.5 Elmar.

  • 55/1.8 Pan-Tachar, chrome, coupled
  • 75/2 Gauss-Tachar, black and chrome, coupled (at cameraquest)
  • 125/2.3 Pan-Tachar, black and chrome, coupled (at cameraquest)

An Elionar Anastigmat 5 cm f/3.5 collapsible lens is known in Leica screw mount. It was made for the Sonne Italian Leica copy.

Enna Edit

  • 85/1.5 Ennaston, chrome, black tripod collar at the base (sold at Westlicht Auction 27 Nov 2005)

FED Edit

  • Industar-10 50/3.5, collapsible. Was never marked "Industar" on the front - merely read FED 1:3,5 F=50mm
  • Industar-26m 52/2.8. Available both with and without focusing tab.
  • Industar-61 52/2.8
  • Industar-61 L/D 55/2.8 (same as the Industar 61, but with a lanthanum coating)

There were also some lenses made before the Second World War that are quite rare now, and would need to be recalibrated to fit the standard lens registration of the Leica thread mount:

  • FED 50/2, collapsible
  • FED 28/4.5, collapsible
  • FED 100/6.3

Fuji Edit

Fuji made Fujinon lenses in Leica mount in the 1950s or 1960s. See Fuji lenses for Leica and Nikon.

  • 90/4 Ogmar, black and chrome, copy of Ernst Leitz Elmar

Hensoldt Edit

A lens marked Dr Hensoldt Optik Wetzlar 1:1.8/f=55 1057 PROTO in a rigid chrome mount has been seen at an eBay auction. An identical lens with s/n 1089 was sold at Christies (8 June 1995) mounted on what was advertised as a Leica Standard copy, with no more precision.

Isco Edit

The Isco Westar 50mm f:3.5, rigid with chrome finish, was the standard lens mounted on the prototypes of the Recta, a rangefinder variant of the Rectaflex.

Kilfitt Edit

Kilfitt lenses had a set of adapters, to attach them on various lens mounts, among them Visoflex.

Kilfitt lens with a fixed 39mm screw mount, rangefinder coupled:

  • 90/3.5 Kilar D, chrome, s/n 212-XXXX

Kodak Edit

K.O.L. Edit

See the main article K.O.L. and Sun lenses in Leica screw mount.

  • K.O.L. Xebec 5 cm f/2, all chrome collapsible, six elements

Sankyō Kōki / Komura Edit

Made by Sankyō Kōki, alias Komura.

  • 28/3.5 W-Komura, black and chrome, hood, "Sankyo Kohki Japan" on beauty ring
  • 35/3.5 W-Komura, black and chrome, no maker mark on beauty ring

  • 35/2.8 Komura, black with wide chrome stripes, focusing tab
  • 80/1.8 Komura, black with wide chrome stripes, "Sankyo Kõki Tokyo" on beauty ring
  • 80/1.8 Tele-Kinegon, black w/chrome front and mount, "S.K. Japan" on beauty ring

Note: The 2 80/1.8 lenses are optically identical and are cosmetically the same except for the beauty ring and focus barrel (black for the Tele-Kinegon and mixed black and chrome for the Komura).

  • 80/3.5 Komura, black and chrome, "Sankyo Kõki Tokyo" on beauty ring
  • 105/3.5 Komura, black w/chrome mount, "Sankyo Kõki Japan" on beauty ring
  • 105/3.5 Komura, black w/chrome front and mount, "Sankyo Kõki Tokyo" on beauty ring
  • 105/3.5 Komura, black and chrome, "Sankyo Kõki Tokyo" on beauty ring

Note: The 3 versions of the Komura 105mm f3.5 appear to be optically identical

  • 105/2.8 Komura, version 1: black w/chrome front and mount, "Sankyo Kõki Japan" on beauty ring
  • 105/2.8 Komura, version 2: black w/chrome aperture ring and mount, "Sankyo Kohki Japan" on beauty ring

Note: The 2 versions of the Komura 105mm f2.8 are not the same physical length and, therefore, must be optically different. Version 2 is longer, and, at common focus distances, its front element is farther from the film plane than is version 1's.

  • 105/2.5 Komura, black with chrome mount, finder, hood, "Sankyo Kohki Japan" on beauty ring
  • 105/2 Komura, black with chrome mount, finder, hood, "Sankyo Kohki Japan" on beauty ring

  • 135/3.5 Komura, black with chrome mount, "Sankyo Kõki Japan" on beauty ring

Note: The chrome and black versions of the Komura 135mm f3.5 are optically different. At common focus distances, the front and rear elements of the chrome version sit closer to the film plane than do the black version's.

  • 135/2.8 Komura, black with chrome mount, "Sankyo Kohki Japan" on beauty ring
  • 200/4.5, all chrome[5]
  • 500/7, black with one chrome ring, breaks in two parts for transport (for Visoflex?)

Konishiroku and Konica Edit

See Konishiroku lenses in Leica screw mount for the lenses made by Konica's predecessor Konishiroku in the 1950s:

  • Hexar 50mm f/3.5 (collapsible)
  • Hexanon 50mm f/1.9
  • Hexanon 60mm f/1.2
  • various experimental or adapted lenses detailed in the main article

See Konica lenses in Leica screw mount for the lenses made by Konica in the 1990s:

  • 35/2 Hexanon
  • 35/2 UC-Hexanon
  • 50/2.4 Hexanon (collapsible)
  • 60/1.2 Hexanon

Koristka Edit

The Italian optical company Koristka, based in Milano, made a Victor 5.5 cm f/3.5 lens in Leica mount for the Gamma, an Italian Leica copy. It is marked F.lli KORISTKA for "Fratelli Koristka".

Kowa Edit

See the main article on Kowa lenses for other cameras.

Kowa made two or perhaps three lenses in Leica screw mount, in very small quantities:

  • Prominar 35mm f/2.8, black and chrome, surely the same lens as on the Kallowide
  • Prominar 100mm f/2, black and chrome
  • Prominar 200mm f/2.8, black and chrome, for use on a reflex housing, announced but perhaps never sold

The Prominar 7.5 cm f/3.5 and 7.3 cm f/3.5 for Leica dating from the late 1940s are not marked as made by Kowa. They are actually similar to the Sun Sola, and were certainly manufactured by Sun or its predecessor. See K.O.L. and Sun lenses in Leica screw mount.

Kristall Edit

A Kristall Krinar Anastigmat 50mm f/3.5 collapsible lens is known in Leica screw mount. It was made for the Kristall Italian Leica copy.

Kyōei / Acall Edit

Lena Edit

The Lena-Q.C 5 cm f/3.5 collapsible lens ostensibly made by Lena Kōgaku was mounted on the Chiyoca camera (see the description there).

Leotax Edit

Showa Kogaku, better known as Leotax, apparently made their own lenses for their very first Leica copies, among which the rare Letana Anastigmat 50mm f/3.5 (see this Leotax page at Cameraquest).

Meyer Edit

Meyer made some lenses in 39mm Leica screw mount at an early date, mostly before World War II. They are marked Hugo Meyer.

Chiyoda Kōgaku/ Minolta Edit

Chiyoda Kōgaku, later renamed Minolta, made a range of Leica screw lenses for its Minolta 35 series camera, a Leica copy made between 1947 and 1958. Chiyoko is a shortened version of the name (CHIYOda KOgaku):

  • 3.5 cm f/3.5 Rokkor, chrome, 4 elements/3 groups, marked "CHIYOKO"
  • 3.5 cm f/1.8 Super Rokkor, black and chrome (?), 6 elements/ 4 groups

  • 13.5 cm f/4 Tele Rokkor, chrome, 4 elements/3 groups, marked "Chiyoko"

Minolta also made a special macro lens in that mount at the time of the Rokkor SLR lenses:

  • 50/3.5 QF-Rokkor macro lens, not rangefinder coupled, part of the Minolta MC/MD lens system

Minolta's last screw mount lens was made in a limited edition:

  • 28/3.5 G-Rokkor, chrome, 2000 made, 1998, same lens as for the Minolta TC-1

Misuzu Kōgaku Edit

The Altanon 5 cm f/2, ostensibly made by Misuzu Kōgaku, was mounted on the Alta camera made by the same company. It was actually a rebadged version of the Tanar 5 cm f/2 by Tanaka. An Altanon 5 cm f/3.5 was also announced but perhaps never sold; it was certainly a continuation of the Lena-Q.C and Reise-Q.C.

See the page on the Alta for more details.

MS Optical R&D Edit

Also named Miyazaki Kōgaku, this company makes:

National Opt Co Edit

Made by National Optical Company, based at Leicester,England, NOC was a 'daughter company of Taylor,Taylor & Hobson which was also located in Leicester and created to deal with high product demand during WW2..

  • 2"/2 Anastigmat, collapsible, focusing tab, all chrome,is based on the "Speed Panchro" design of Horace W. Lee (of Leicester)and looks similar to the collapsible Taylor & Hobson 2"/2 Anastigmat which was the standard lens fitted to the Reid camera.They use a similar barrel and focussing mount made by Cook & Perkins, but it is not a "clone" of this lens and is more akin to the T,T,& H Amotal. All known serial numbers start 354xxx, the last 3 digits (xxx) being engraved on the lens barrel of each lens.Could this mean that each lens cell was indiviually matched to a barrel?.One unusual feature of the National Optical Co.2"/2 Anastigmat is that unlike most camera lenses with depth of field scale the N.O.C has a central depth of field index of "0" rather than the usual plain index mark.

British and U.S.patent numbers are engraved on each barrel.

  • 105/3.5 Trinol Anastimat, chrome and black, or black with chrome mount, mount marked Stewartry and Made in Scotland, with Stewartry zoom frame finder

The Trinol lens head is made by National Optical Company and marked as such in fine print, but has no maker marking.

See the main article Zuiko 4cm f/2.8 for Leica.

Some examples of the Zuiko 50/1.5 wartime X-ray lens reportedly appeared on the Japanese market after 1945, remounted in Leica screw mount by third-party workshops. See Zuiko.

Orion / Supreme Edit

See the main article on Supreme lenses.

  • Universal Supreme 5 cm f/3.5, all chrome, collapsible

Reise Edit

The Reise-Q.C 5 cm f/3.5 collapsible lens made by Reise was mounted on the Chiyoca camera (see the description there).

Riken / Ricoh Edit

Riken, predecessor of Ricoh, announced the Riken No.1 Leica-type 3×4 cm camera in 1938; its Riken 50mm f/3.5 lens perhaps had an interchangeable Leica mount, but nothing is confirmed so far. The camera was finally released as the Gokoku; it normally has a fixed lens, but at least one example is known with a Leica-mount Ofunar 50mm f/3.5, which was perhaps not made by Riken but by Tomioka or Ōfuna. Finally, the Neutar 50mm f/3.5 lens mounted on the Ricohl IIB normally has a slightly different screw mount, incompatible with the Leica, but at least one example is known in standard Leica mount. See Gokoku and Ricohl for these three lenses.

In the late 1990s, Ricoh made two lenses in Leica screw mount, in limited editions:

  • 21/3.5 GR, 1000 made in chrome and 700 in black, 1999, same lens as the Ricoh GR-21
  • 28/2.8 GR, 2000 made in chrome and 1000 in black, 1997, same lens as the Ricoh GR-1

  • Choroplast 4,5/35
  • Neoplast 5,6/85

Steinheil Edit

Steinheil made some lenses in M39 mount. It was essentially the optical range developed for their own Casca model. They were all in chrome finish. Some of these lenses also existed with a Tower engraving on the barrel, to be sold with a Sears Tower Leica copy.

  • 35/4.5 Orthostigmat, rotating mount, two focusing tabs (exists with "Tower" engraving)

Taylor, Taylor & Hobson Edit

Taylor, Taylor & Hobson made the collapsible 2" f:2 Anastigmat as the standard lens for the Reid British Leica copy.

They also made a rigid 2" f/2 Cooke Amotal Anastigmat lens for the Bell & Howell Foton camera. Some of them appear in Leica screw mount, due to Peerless(US) arranging for an Italian firm to mount them in rather crude Leica screw mounts so that they could fit them to Leica camera imports and undercut the Leica camera prices fixed by Leitz, who could only fix the prices of Leica cameras fitted with Leica lenses.

See also the lens made by a Taylor,Taylor & Hobson subsidiary THE NATIONAL OPTICAL COMPANY

Telesar Edit

Marked Telesar, maker unknown.

  • 35/3.5 W.Telesar, black and chrome, similar to the Acall and Komura

Tōkyō Kōgaku Edit

(State, Simlar and Topcor lenses.)

See Tōkyō Kōgaku lenses in Leica screw mount.

Tomioka Edit

The Lausar 5 cm f/4.5 and 5 cm f/3.5 collapsible lenses of the Lausar and Baika cameras are certainly interchangeable with Leica screw mount. The Ofunar 50mm f/3.5 found on a Gokoku with Leica mount was perhaps made by Tomioka too, or by Ōfuna (see Gokoku and Ricohl).

In the late 1950s, Tomioka was certainly the supplier of the Yashinon and Yashikor 5 cm lenses offered by Yashica on the Yashica YE and YF. It might also have supplied the 50mm Honor lenses (see the discussion there), and there is a report of a Tominon C 50/1.8 lens in Leica screw mount, said to be "similar to the Honor lens" by Zuihō.[9]

Trixar Edit

A Trixar Anastigmat 50mm f/3.5 collapsible lens is known in Leica screw mount. It was made for the Wega Italian Leica copy.

Voigtländer Edit

Voigtländer Braunschweig Edit

Voigtländer made some lenses in 39mm Leica mount. They are very rare and sought after.

Cosina Voigtländer Edit

See Cosina Voigtländer.

Wega Edit

A Wega Anastigmat 50mm f/3.5 collapsible lens is known in Leica screw mount. It was made for the Wega Italian Leica copy.

Yasuhara / Phenix Edit

Yasuhara made a Yasuhara MC 50/2.8 lens for the T981. It was rigid, in chrome finish with a focusing bar (you can see it in this page of the Ichrizuka site by Madam-san).

Phenix made a Phenix MC 50/2.8 lens for the Phenix JG50, an evolution of the Yasuhara T981. It was a four element collapsible lens, always in chrome finish with a focusing tab.

Y.K. Optical (Kobalux, Avenon, etc.) Edit

The small Japanese company Y.K. Optical from Yokohama made two wide angle lenses in Leica mount. They were sold under the names Kobalux, Avenon, Pasoptik, Bower or Adorama.

  • 21/2.8 Super Wide, chrome or black
  • 28/3.5 Wide, chrome or black

Zeika Edit

See the main article Rojar 3.5cm f/3.5 for Leica.

Carl Zeiss Jena Edit

See Zeiss 39mm screw lenses.

Zuihō Edit

See the main article on Honor lenses.

Zuihō, maker of the Honor S1 and Honor SL Leica copies, rebadged a few lenses under its own Honor brand:

  • Honor 50mm f/2
  • Honor 50mm f/1.9

The 35mm and 135mm lenses do not display Zuihō's name, and were perhaps unrelated:

  • Honor or W.Honor 35mm f/3.5
  • Honor 135mm f/3.5

Zunow Edit

Notes Edit

  1. This page of the Canon Camera Museum.
  2. See for example this forum thread at kyphoto.com. This page at Sovietcamera discusses lens compatibility on early Fed and Zorki and says that "The Leica screw mount is 39mm × 26 tpi (threads per inch) thread of the screw-mount Leica. All the Soviet cameras with 39mm screw mount are the same as Leica."
