The standard version is listed as:

„HEKTOR“ 5 cm 1 : 2,5 Besonders lichtstarkes Universal-Objektiv, Fassung versenkbar.

1934–1935: Changes in Codeword Usage and Regional Variations

In the German catalogue Liste Photo Nr. 7325 b. of December 1934, the lens is listed as:

„Hektor“ 5 cm 1 : 2,5 Besonders lichtstarkes Universal-Objektiv, Fassung versenkbar.

The description may be translated as “Hektor 5 cm f/2.5, particularly fast universal-purpose lens, with collapsible mount”. The assigned codeword is Hekto for the standard version and Hekto chrom for the chromium-plated version.

In contrast, the U.S. catalogue Booklet No. 1227 – 3rd Edition of March 1935 lists the standard version as HEKTORKUP and the chromium-plated version as HEKTO-CHROM. The corresponding code numbers are 50,340 and 50,350 respectively. The listed retail prices were USD 67.50 and USD 69.75.

In the U.S. catalogue Booklet No. 1244 of September 1935, the lens is listed as “LEITZ Anastigmat HEKTOR, 50mm focus, f:2.5 (speed lens), angle of view 48°, in focusing mount.” The assigned codeword is HEKTO, with code number 50,350. The listed retail price was USD 67.50.

As discussed in the section on the Leica Hektor 28mm f/6.3, the lens listed in this catalogue appears to correspond to the chromium-plated version. However, in the German catalogue Liste Photo Nr. 7325 b. of December 1934, the codeword Hekto was assigned to the standard version. These records suggest that codeword usage may have varied according to market and period.

1934–1935年:コードワード運用の変化と市場差異

1934年12月のドイツ語カタログ(Liste Photo Nr. 7325 b.)では「„Hektor“ 5 cm 1 : 2,5 Besonders lichtstarkes Universal-Objektiv, Fassung versenkbar.」と表記されている。コードワードは標準仕様のニッケル仕上げがHekto、クローム仕上げがHekto chromである。

一方、翌1935年3月の米国向けカタログ(Booklet No. 1227-3rd Edition)では、標準仕様がHEKTORKUP、クローム仕上げがHEKTO-CHROMと表記されている。コードナンバーはそれぞれ50,340と50,350であり、価格は67.50ドルと69.75ドルである。

1935年9月の米国向けカタログ(Booklet No. 1244)では「LEITZ Anastigmat HEKTOR, 50mm focus, f:2.5 (speed lens), angle of view 48°, in focusing mount」と表記されている。コードワードはHEKTO、コードナンバーは50,350である。価格は67.50ドルである。詳しくは Leica Hektor 28mm f/6,3 コードワードの変遷(1935–1953) の項で述べたとおり、このカタログに記載されているレンズはクローム仕上げであると考えられる。

一方、1934年12月のドイツ語カタログ(Liste Photo Nr. 7325 b.)では、コードワード「Hekto」はニッケル仕上げに使用されている。このことから、Hektor 50mm f/2,5においては、地域や時期によってコードワード表記の運用に差異があったと考えられる。なお、1935年3月のクローム仕上げと比較すると価格はやや低下しており、標準仕様であったニッケル仕上げと同価格になっている。
