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).

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. (It has been said that early Russian cameras used "M39 × 1", with 1 mm thread, but no conclusive evidence has been provided so far.)
The film-to-flange distance was not standardized on very early Leica (until 1931) and early Fed and Zorki (until the early postwar years). 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:
- Leica I/II/III
- Canon rangefinders
- Voigtländer Bessa
- the Ukrainian FED, Zarja
- the Russian Zorki, FED, Leningrad and Drug
- the British Corfield Periflex and Reid
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:
Leica screw mount is also a very common mount for enlarger lenses. These lenses do not necessarily match the flange focal distance of Leica cameras, and may not focus to infinity when mounted on a camera.
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.
This list does not include lenses designed specifically for use in enlargers.
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.

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:
- LR-T/PL 2.7/420mm
- LR-T 4/480mm
- TE-N 11/600mm
- TE-N/PL 16/925mm
- EX-T 22/1250mm
- EX-T/PL 32/2000mm
Probably for military use only.
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.

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".
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.
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.

Chiyoda Kōgaku/ Minolta
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 W. Rokkor QF, black and chrome, 6 elements/4 groups
- 45mm f/2.8 Super Rokkor, chrome, 5 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
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.
Also named Miyazaki Kōgaku, this company makes:
- MS-Mode-S 50/1.3 lens, for both Leica and Nikon S; see MS Optical R&D.
- MS-Mode-AH Apoqualia 50/3.5 lens, for Leica; see MS Optical R&D.
National Opt Co
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

Riken / Ricoh
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

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.

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

- 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."
