At the spring fair in Leipzig in 1939, the Praktiflex film camera was presented as an amateur SLR camera for 135mm film format. The work on the camera has been carried out under the direction of Benno Torsch and Alois Hoheisel since 1937.

Praktiflex is a brand of German single-lens reflex cameras manufactured by Kamera Werkstätten Guthe & Thorsch from 1938 to 1951. Praktiflex, the serial production of which began in 1938, became the third small-format SLR camera in history (after the German Kine-Ekzakt by Ihagee Kamerawerk and the Soviet Sport). It gained popularity and was produced for over 10 years with little or no design change. The cost of the camera was 120 Reichsmarks. In the 1950s, the Praktiflex FX camera with flash connectors was also produced in the GDR.

History

The trade name Praktiflex was registered by Charles Adolph Noble in 1939, on April 14, and existed until the end of World War II.

The patent for the camera did not exist, and in 1949, with minor alterations (in 1946 Siegfried Brehm reworked the mirror lifting mechanism), the camera began to be produced at the facilities of VEB Kamera und Kinowerke, under the name Praktica FX.

Praktiflex was originally threaded lens M40x1, later the camera got a unified M42x1. The first Praktiflex cameras have Gothic lettering on the front, and are the most valuable to collectors. The production of cameras started in 1941, before that, prototypes were mainly presented to the public.

The first generation had a focal-plane gate with fabric shutters, M40x1 thread for mounting lenses, simple and slow mirror return mechanism, shutter speeds from 1/20 to 1/500 seconds, shaft viewfinder with an image magnifier, mount lens М40х1, light metal body and frame counter on the top of the camera. Cameras for a long time did not have a flash sync connector, so sync contact was introduced by amateurs with their own hands.

In the second generation of these lenses, the main transformations concerned the mechanism of lifting and returning the mirror, changes in the time series on the exposure disc, and the transfer of camera controls. Also, work was carried out to increase the service life shutter.

The second generation of Praktiflex was produced in parallel with a mount for lenses with an m42x1 thread, the final transition to the m42 thread took place in 1949 with the release of the Praktica FX models. Note that lenses with m42x1 and m40x1 connectors have different flange focal lengths. For m40x1 - 44mm, for m42x1 - 45,5mm. Known color modifications of cameras of the first and second generation.

The entire series of Praktiflex film cameras was released in a total of about ~ 60000 copies.

What kind of film is needed for a Praktiflex camera?

For Praktiflex cameras, any 135 type (35mm) film is suitable, in standard spools. You can use both black and white and color, you can wind the film yourself. Can be bought from masters... A budget hobbyist color film from Fujifilm or Kodak, black and white Tasma, works well. Films c ISO 400 are suitable for low light conditions, and on films with ISO 200 is best for shooting outdoors in clear or slightly cloudy weather.

Praktiflex variants produced at different times

Established lensmy cameras were:

  • 5 cm f / 4.5 Zeiss Tessar
  • 5 cm f / 2.8 Schneider-Kreuznach Xenar
  • 5 cm f / 2.0 Schneider-Kreuznach Xenon
  • 5 cm f / 2.9 Victar Anastigmatic
  • 5,8 cm f / 2.0 Zeiss Biotar
  • 8,5 cm f / 4.0 Zeiss Triotar
  • 12 cm f / 4.5 Meyer Trioplan

The lens mount is threaded, M40x1 (after 1949 - M42 × 1).

Since most of the cameras were made with modifications "on the fly", within the series you can find different sets of exposures, finishes, absence / presence of sync contacts on the panel. Basically, the series has undergone minor changes, and therefore cameras in some way unique.

A total of 59716 cameras were produced, of which

  • 33900 - first version
  • 25816 - second version

From 1946 to 1948 the camera was supplied to the USSR as reparations.

After the merger in 1949 of the factories "KW" and "Ihagee", the products received a new brand - "Praktica".

 

The predecessor of the very first "Praktika" is the mirror Praktiflex, produced by Kamera-Werkstätten Guthe & Thorsch GmbH ("KW"), equipped with a non-standard M40 × 1 thread for attaching interchangeable lenses. This camera is considered the third small-format "SLR" in the world after the Soviet "Sport" and the German "Kine-Ekzakty".

After the occupation of Germany, the private enterprise KW was nationalized and renamed VEB Kamera-Werkstätten Niedersedlitz, working on orders from the Soviet military administration. In 1947 she was given a technical assignment for a new camera with a threaded M42 × 1 optics and a shutter speed range from 1/500 to 1/2 of a second. Under the leadership of the designer Siegfried Boehm, the Praktiflex camera is being modernized, an improved sample of which was presented in the fall of 1948. Serial production begins in January 1949 under the new name Praktica, as KW became part of the Ihagee company.

Further improvements were made to the acquisition of a sync contact, a constant sight mirror and pentaprism, as well as a jumping diaphragm, which first appeared in the world in the Praktica FX2 model in 1956. Since the transformation of Praktiflex into Praktika, two generations of cameras based on cloth focal gatee with horizontal curtain movement, such as Leica. One of the most famous among the second generation of Nova was the Praktica Super TL model, which was also popular in the Soviet Union, where it turned out to be the first affordable camera with TTL-exponometer. The earlier Praktica Mat was the first to receive such an exposure meter in Europe.

TECH SPECS

"Praktiflex II"

  • Used photographic material: 35 mm apertured film in standard cassettes (type 135) (left cassette, right - take-up spool with rewind)
  • Frame size: 24 × 36 mm
  • Gate: curtain, with horizontal movement of fabric curtains. Shutter speed scale - 1/25, 1/50, 1/100, 1/500 s and "B" (the duration corresponds to the time the shutter button is held down shutter). Pre-WWII cameras have a shutter release button shutter located in the upper part of the body; later, in order to increase the clarity of the images, it was moved to the front surface of the case. Before the war, a prototype camera with a shutter speed range of 1s - 1 / 1000s was presented, but it was not possible to start mass production.
  • Platoon shutter and transportation of the film is carried out simultaneously by rotating the head in the upper part of the case on the right.
  • The head is equipped with a mechanical frame counter.
  • The rewinding of the film into the cassette is performed by the rewind head (in the upper part of the case on the left) with the "R" flag extended, disabling the cocking mechanism shutter.
  • Viewfinder: mine, with frosted glass and folding magnifier; "Sports" viewfinder of frame type with the hatch in the front wall of the shaft open.
  • Case: metal case with a removable back cover (lock on the left side of the case), finished in black genuine leather or leatherette; bottom - aluminum tripod nut with 3/8 ″ thread (also serves for mounting in a leather case).

 

Over the years, the camera has undergone several upgrades. Presumably, from 1941 to 1946, the camera was produced intermittently.

  • 1939: Early camera releases feature no strap tabs and large cocking and rewinding knobs. In the first versions, the frame counter was located on the upper part of the cocking handle, then it was moved under it. The name was written in Gothic script. Later, the font was changed to an imitation of handwritten one.
  • 1940: Reduced the diameter of the rewind handle (Ø21mm, while the cocking handle was Ø27mm). In addition to the standard version, cameras appeared, pasted over with brown, dark brown, red and dark green leather. The metal parts of some cells were painted gray or black. Added belt clips.
  • 1941: The clamps were changed to standard "lugs" on the sides of the case.
  • 1946: The camera is only available in black with a white name
  • 1947: Return to the nickel-plated version. The frame counter returns to the top of the cocking knob. [4] In the same year, the camera was replaced by a modified version, conventionally called Praktiflex II. It was distinguished from the original version by a different shutter speed selection mechanism, a shutter release button on the front panel, next to the lens and a redesigned design. shutter... The size of the control knobs has also changed (Ø16mm at the rewind knob, Ø25mm at the cocking knob) and the button for disabling the transport of the film for winding the removed cassette has been moved to the top panel next to the cocking knob. The name is again written in the Gothic script, as in the first practiceflexes.

After 1949, when fasteners were introduced lens M42x1, it was installed on Praktiflex. Presumably, the production of the second model was discontinued in 1951.
