The '''39mm screw mount''' — also called '''Leica Thread Mount''' ('''LTM '''), '''Leica Screw Mount''' ('''LSM'''), or '''M39''' — was introduced by [[Leica]] with the model I (C), and used on all the Leica models until the bayonet mount [[Leica M3|M3]]. The mount was adopted on many [[Leica copy|Leica copies]] and other 35mm [[rangefinder camera]]s.

== Description ==
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 (device)|rangefinder]] coupling. Very early [[Canon]] (J mount) used an incompatible '''M39 × 1/24"''' screw mount, 39mm in diameter but with 24 threads per inch.<REF> [http://global.canon/en/c-museum/product/film4.html This page of the Canon Camera Museum] - Spec section. </REF> (It has been said that early Soviet cameras used "M39 × 1", with 1 mm thread, but no conclusive evidence has been provided so far.)<REF> See for example [https://web.archive.org/web/20090228083144/http://www.kyphoto.com/classics/forum/messages/6790/12397.html this forum thread at kyphoto.com] (archived). [https://web.archive.org/web/20120111113052/http://sovietcamera.110mb.com/fed1/ This page at Sovietcamera] (archived) 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."  </REF>

The film-to-flange distance was not standardized on very early Leica (until 1931)<REF> [https://web.archive.org/web/20140219203640/http://www.ph.utexas.edu/~yue/misc/LeicaLTM.html This page by Andrew Yue] (archived). </REF> and early [[Fed]] and [[Zorki]] (until the early postwar years).<REF> [https://web.archive.org/web/20120111113052/http://sovietcamera.110mb.com/fed1/ This page at Sovietcamera] (archived). </REF> 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]] / [[Leica II|II]] / [[Leica III|III]]
* [[Canon II/III/IV|Canon rangefinders]]
* [[Cosina]] Voigtländer [[Bessa]]
* the Soviet [[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. Four such systems are:
* the [[Braun]] [[Paxette]]
* early models of the Soviet [[Zenit]]
* the [[Great Wall DF]] Chinese SLR
* Soviet half-frame [[Chajka]] 2, 3 and 2m models 
(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 [[Opema]].)

== List ==
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.'''''

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

== [[Kowa]] ==
''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 7.5cm f/3.5 and 7.3cm 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 ==
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.

== [[Misuzu Kōgaku]] ==
The Altanon 5cm 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 5cm f/2 by [[Tanaka]]. An Altanon 5cm 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#Specific lenses|Alta]] for more details.''

== [[MS Optical R&D]] ==
Also named Miyazaki Kōgaku, this company makes:
*MS-Mode-S 50/1.3 lens, for both Leica and [[Nikon rangefinder models|Nikon S]]; see [[MS Optical R&D]].
*MS-Mode-AH Apoqualia 50/3.5 lens, for Leica; see [[MS Optical R&D]].

== [[National Optical Company]] ==
NOC of Leicester, England, was a daughter company of Taylor,Taylor & Hobson (also located in Leicester), created to deal with high product demand during the Second World War.
* 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.

== Riken / [[Ricoh]] ==
'''Riken''', predecessor of '''Ricoh''', announced the [[Gokoku and Ricohl|Riken No.1]] Leica-type 3×4cm 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 and Ricohl|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 [[Gokoku and Ricohl|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 GR21]]

'''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)
* 50/2 Quinon, 6 elements/3 groups (Sonnar type), close focussing to 18"

== [[Taylor-Hobson|Taylor, Taylor & Hobson]] ==
'''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 lenses made by TT&H subsidiary [[39mm screw lenses#National Optical Company|National Optical Company]].

== Telesar ==
Marked '''Telesar'''; maker unknown.
* 35/3.5 W.Telesar, black and chrome, similar to the [[Acall 39mm screw lenses|Acall]] and [[Komura 39mm screw lenses|Komura]]

== [[Tōkyō Kōgaku]] ==
(State, Simlar and Topcor lenses.)

''See [[Tōkyō Kōgaku lenses in Leica screw mount]].''

== [[Tomioka]] ==
The Lausar 5cm f/4.5 and 5cm 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 and Ricohl|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 5cm lenses offered by [[Yashica]] on the [[Yashica YE]] and [[Yashica YF|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]].<REF> HPR, ''[[Sources: English language#Leica Copies|Leica Copies]]'', p.414. </REF>
