85MM SCREW MOUNT LENSES
8.5cm f/1.5 Summarex
Alexander Smakula filed a patent for the process of vapor deposition of anti-reflective coatings on glass lenses at Zeiss in Jena in 1935364. Dr. Max Berek developed a symmetrical 7-element, 2-pair modified Gauss design, for which he obtained a patent in 1937116.
During the Second World War, companies involved in the production of war-critical optical equipment were required to share their specialized knowledge with one another364. As a result, Leitz was obligated to apply the coating process patented by Zeiss to optical components for war-relevant equipment starting in 1941, which likely included some Leica lenses364. Dr. Max Berek created the name "Summarex" by combining the well-known Leitz SUMMAR trademark with the name of his pet Alsatian dog, Rex116.
Prototype
9cm f/1.5 Summarex Prototype
In his "Geburtstage der Leitz-Foto-Konstruktionen ab 1927" book, Wilhelm Albert dated the "birthday" of 9cm f/1.5 Summarex lens ("Objektiv Summarex 9 cm 1:1,5 mit E.-Kupplung") as September 9, 1939, and noted himself as designer573. This lens was widely considered to be a prototype of the 8.5cm f/1.5 Summarex lens512.
An example of such prototype, number 541021, dated circa 1940429, was illustrated in Mr. Lars Netopil's "Rare Leica" book in 2014594. It was sold for 32000 Euros including buyer's premium at the 7th Wetzlar Camera Auction on October 11, 2025429. The lot was described as "The early experimental models of the famous Summarex were still labelled 9 cm...The lens offered here in a significantly different design from the series-produced lenses...Provenance: Property of a European collector."429.
In the production book of Leitz Company, the serial numbers from 541051 to 541100 were reserved for black lacquered prototypes512. It was likely that not all of these numbers were utilized, so the reserved numbers were frequently employed for repairs512. According to the records, only six lenses were produced, and they were numbered 541053, 541054, 541055, 541056, 541057, and 541058512. These were partially branded under the name "Summar"512. Of these 6 lenses:
- The 9 cm f/1.5 Summar number 541056, produced in October512 1940, was uncoated439. The lens was illustrated on page 71 of James L. Lager's "Leica: An Illustrated History - Volume 2 - Lenses - Signed Deluxe Limited Edition" book542. The photograph was credited to "Bellon photo"542. Also, the lens was referenced in Daniel Claeyssen's "Ein unbekanntes Objektiv für die Leica mit Schraubgewinde: Summar 1,5/90" article of Vidom 33 in 1986439.
- The company’s shipping records indicated that on November 25, 1941, the Leitz shipped a prototype 9cm f/1.5 Summarex lens with serial number 541058 to Berlin for testing and evaluation116. This lens was featured in the Leitz brochure titled "Auswechselbare Leica-Objektive"116 published in 1943512. This early version of the lens had straight rear section, which was different from the design of later models512. This lens was illustrated on page 71 of James L. Lager's "Leica: An Illustrated History - Volume 2 - Lenses - Signed Deluxe Limited Edition" book542.
Black paint 8.5cm f/1.5 Summarex
In his "Geburtstage der Leitz-Foto-Konstruktionen ab 1927" book, Wilhelm Albert dated the "birthday" of 8.5cm f/1.5 Summarex lens with differential compensation ("Objektiv Summarex f=8,5 cm 1:1,5 mit Differenzausgleich") as October 4, 1940, and noted himself as designer573. The black lacquered 8.5cm f/1.5 Summarex (later code-named SOOCX82) lens was added to the product range on July 15, 1943, and the production began with the serial number 593001512. A total of only 276 lenses within the serial number range from 593000 to 593349 were produced, indicating that 74 serial numbers were not used512.
Known Lenses
The first 100 lenses (from serial number 593001 to 593100) were delivered to the Wehrmacht in Berlin during July and August 1943512.

Lenses following the serial number 593101 were coated and featured only the international geometrical aperture markings512. The aperture index was displayed as an engraved arrow shape within a half circle, inlaid with white paint512. Notably, unlike the chromed Summarex lenses, the black lacquered lenses indicated the aperture index increasing from left to right512. Therefore, to close the aperture, the aperture ring had to be turned clockwise512. Additionally, the rear portion of the one-piece mount lacked the fine knurled ring found on later two-piece mounts116. An 85mm parallax-corrected saddle-type bright-line finder, designated SOOCB, was cataloged in 1943116. A special clamp-on, non-reversing black brass lens hood was provided, along with a uniquely sized black brass cap that fit the lens directly116. In contrast, later chrome lenses featured reversible bayonet hoods and slightly larger chrome caps that fit the reversed hoods116.
The black lacquered post-war Summarex 8.5 cm lens could be seen as a transition between the prototypes of 9cm f/1.5 Summar lens and the later, production chrome versions512. The patina finish on the distance scale was replaced with brushed chrome116. The dual f-stop scale was removed around serial number 593200116.
Due to high manufacturing costs, its production was ultimately halted with the introduction of the first version of chrome Summarex, starting with the serial number 593350512. The reversible lens hood and chrome cap were introduced with this lens107.
8.5cm f/1.5 Summarex in chrome finish
There were 6 different variants of chrome version, according to Dr. Bahman Bawendi's research512:
Version 1 - 593XXX series
The first chrome Summarex, with the serial number 593350, was exported to the Leitz branch in New York on December 8, 1949512. The production of this series concluded with the lens having the serial number 593500 on March 17, 1950512. This means that only 150 of these lenses were ever produced, making them even rarer than the very hard-to-find black lacquered versions512. The distribution records provide the shipping date and destination but do not indicate the production date512. However, the serial number sequence of 593xxx suggests that the first chrome lenses were assembled from parts that had been prepared earlier512. All lens barrels of the this version featured the highly reflective 'wartime chrome' plating512. Among the chrome Summarex lenses known to the author of this website were: 593328, 593366, 593363, 593376, 593416, 593424, 593429, 593444.
The source of the following images is the "The Summarex 8.5 cm f/1.5" article written by Dr. Bahman Bawendi published in 7/2011 Leica Fotografie International magazine512:


Some of the lenses of this version were:
- had feet scale and were engraved "feet" (like on 593328, 593366, 593444), while others had meter scale and were engraved "m" (like on 593376, 593424, 593429)
- some had dot-shaped aperture ring index mark (like on 593363, 593366), while others had triangle-shaped aperture ring index mark (like on 593328, 593376, 593416, 593424, 593429, 593444)
- some had red engraved depth of field (like on 593328), while others had black engraved depth of field (593366, 593376, 593424, 593429, 593444)
Version 2 - 732XXX series
The serial numbers for the second chrome version, produced between 1950 and 1951, range from 732001 to 732500512. Apart from that, all characteristics of the first chrome version also applied to the lenses within this sequence of serial numbers512. All lens barrels of the this version featured the highly reflective "wartime chrome" plating512. Some of these lenses had feet scale and were engraved "feet", while others had meter scale and were engraved "m".
Among the lenses were:
- 732001, that was auctioned off at Christie's on November 19, 1987.

Version 3 - 823XXX series
The serial numbers for the third version began with 823001 in 1951 and concluded with 824000 in 1952512. The depth of field index featured more widely spaced numbers512. Additionally, the distance setting marker was redesigned to be linear and was inlaid with red paint on some of the lenses512. In the third version, the casing's surface was matte chrome512. The front ring's abbreviation for 'number' changed from 'No.' to 'Nr.'512.

Version 4 - 940XXX series
This version had serial numbers ranging from 940001 to 941000 and was manufactured between 1952 and 1954512. Rear section of the lens barrel had been redesigned resulting in the removal of the finely corrugated rings512. Lenses of this variant featured a smooth double ring beneath the depth of field scale, where the tripod mount protruded512. Beginning with the fourth version, the middle section of the front ring, which was located in front of the aperture, had a shiny chrome finish instead of the matte finish seen in version 3512. This shiny chrome matched the front part to which the lens hood was attached512. Lenses of this version had a red R-index for infrared film512, a feature that had been eliminated by Leitz on their early post-war lenses due to the unavailability of infrared film116.

This batch also introduced an improved lens hood and the bright-line 85mm finder, designated SGOOD, in 1952116. The number of slots in the post-war hood was reduced from four to two for increased manufacturing efficiency116. A change in the color of the lens coating occurred at this time, shifting from light blue to magenta116.

Version 6 - 1151XXX series
The sixth variation was produced from 1958 to 1962, spanning serial numbers 1151001 to 1151450512. However, instead of 450, only 375 lenses were believed to have been built onto which those serial numbers were distributed irregularly512. The step beneath the aperture, over which the tripod mount protruded, was in the form of a compact ring512.
In 1967, the last four lenses in this block of serial numbers were delivered512. Some of the lenses of this variant were equipped with the SOOCX-ISBOO adapter straight from the factory512. The engraved depth of field markings, as well as the markings for infrared film (R), were low in red paint512. The index line for distance setting was marked in black and shaped like a wedge at its end512.

Closing Remarks
The 8.5cm f/1.5 Summarex was last listed in the catalog in 1962, with a retail price of 360.00 USD116. According to Helmut Lagler, however, overall, there were 4550 lenses produced between 1943 and 1954, with serial numbers ranging from 593001 through 1151450439. The production of this lens came to an end due to the introduction of the more versatile and less expensive 9cm f/2 Summicron (model SOOZI) in 1957116.
