Leica IIf

Leica IIf

The Leica IIf is a 35mm screw-mount rangefinder camera introduced by Ernst Leitz Wetzlar in 1951. It belongs to the postwar Leica f-series and can be understood as the simpler companion to the Leica IIIf, using a similar body concept but omitting the front slow-speed dial [1].

Unlike the Leica If, the IIf has a built-in coupled rangefinder and a built-in optical viewfinder. Unlike the IIIf, it does not offer the slow shutter speeds controlled from the front of the camera. This placed the IIf between the minimal technical-body Leica If and the fully featured Leica IIIf, giving photographers a compact LTM rangefinder with flash synchronization but without the extra slow-speed mechanism[2].

The IIf uses the Leica Thread Mount, also known as LTM or M39, and accepts standard rangefinder-coupled screw-mount lenses. Like other Barnack Leicas, it uses bottom loading, separate rangefinder and viewfinder eyepieces, manual film advance and rewind, and a horizontal cloth focal-plane shutter. The fixed optical finder is intended for approximately 50mm framing and does not display projected framelines, so wider or longer lenses require an accessory finder.

The camera was made in Black Dial and Red Dial versions. Black Dial examples use the earlier shutter-speed progression, while Red Dial examples use the later revised sequence. Early cameras generally have a top speed of 1/500s, while later Red Dial 1/1000 versions introduced the higher top speed. Because these versions affect both usability and collector classification, the shutter-speed dial should always be checked directly[3].

History

Development and Launch

The Leica IIf replaced the Leica IIc in 1951 as the rangefinder-equipped but simplified model in the screw-mount Leica lineup. Pacific Rim Camera describes it as a Leica IIIf without slow speeds, with a vulcanite-covered patch where the slow-speed dial would have been placed. This made it less expensive and mechanically simpler than the IIIf while retaining the postwar synchronized shutter system.

Production Evolution

Production ran from 1951 to 1956. Leica Wiki lists 35,091 cameras produced, while its serial-number table lists 35,499 assigned serial numbers, reflecting the usual difference between assigned blocks and final production totals. The main variants are Black Dial, Red Dial 1/500 and Red Dial 1/1000. The later 1/1000 version appeared in 1954, with Summichronica noting serial number 676564 as the starting point for the 1/1000s shutter-speed change.

Serial Number Batches

Leica IIf serial numbers are non-contiguous. Leica Wiki lists assigned blocks including 451001 to 455000, 570001 to 575000, 611001 to 615000, 650001 to 655000, 675001 to 682000, 711001 to 713000, 762001 to 765000, 787001 to 789000, 799001 to 799999, 808501 to 810000 and 820501 to 822000. This means the visible broad range from 451001 to 822000 should not be treated as continuous production.

Special Variants

Recognized Leica IIf variants include Black Dial, Red Dial 1/500, Red Dial 1/1000, Betriebskamera or works-camera engravings, Eigentum property-camera engravings, and examples with sharkskin covering. These variants are important because small engraving and covering differences can affect collector interest considerably.

Collector Notes

The key identification point is the absence of the front slow-speed dial. A true IIf should have the coupled rangefinder and viewfinder windows of the II-series body, but the front position used for the IIIf slow-speed dial should be covered by a vulcanite patch or equivalent body covering. The accessory shoe is also noted by Leica Wiki as a spring-blade type fixed by two screws.

Collectors should distinguish the IIf carefully from the IIc, IIIf and factory-upgraded bodies. CameraQuest notes that screw-mount Leicas were often factory-upgraded during their working lives, sometimes retaining their original serial numbers after conversion [4]. For that reason, serial number, shutter-speed dial, flash-sync dial, top-plate engraving, accessory-shoe construction and the front slow-speed-dial area should all be checked together.

The Leica IIf is valued because it offers much of the practical postwar Barnack Leica experience in a cleaner and slightly simpler form than the IIIf. It is less feature-rich than the IIIf, but its lighter specification, flash synchronization and rangefinder-coupled LTM mount make it a historically important and usable screw-mount Leica for collectors and photographers.
