The '''Paxette electromatic''' is a series of [[35mm]] cameras produced by [[Braun]] from 1959 to early 1964. They all feature the same compact body, a built-in [[selenium meter]] and coupled with it a trap-needle exposure automatic. When launched in 1959 the original version was advertised as the ''world's first and only truly fully automatic 35mm camera'' causing a legal dispute with [[Agfa]] who launched its superior [[Optima]] a few weeks earlier. Despite the automatic aperture the original electromatic is a rather simple camera with a fixed focus lens and only one shutter speed and film speed setting. The later '''Paxette electromatic II''' (launched in 1960) has a better lens, manual focussing and fully automatic exposure setting, similar to the much more successful Optima. The '''Paxette electromatic III''' (launched in 1961) offers more manual control and shutter priority exposure automation. With the launch of the II and III models the original electromatic was rebranded as '''Paxette electromatic I''' and later succeeded by the model ''Ia'', which is almost as simple but features an exchangeable lens.

In 1959 the '''[[Braun]] Paxette electromatic''' was advertised as the world's first fully automatic [[35mm ]]camera. Its [[selenium meter]] controlled the [[Lens#Aperture|aperture]] and gave a red/green light sufficiency signal in the viewfinder. But other automatic functions were missing. Instead, the focusing of the Ennagon 1:5.6/40mm lens was fixed, and it had only the single shutter speed 1/40 sec. Film speed had to be selected manually to obtain proper exposure by the aperture system.

In 1959 the original ''' Paxette electromatic''' was advertised as the ''world's first and only fully automatic 35mm camera''. Its [[selenium meter]] controls the [[Lens#Aperture|aperture]] and gives a green light sufficiency signal in the viewfinder. But other automatic functions are missing. Instead, the focusing of the Ennagon 1:5.6/40mm lens is fixed, and it has only the single shutter speed 1/40 sec. Even film speed is fixed and only film with 17/18 DIN (40/50 ASA) can be used. The aggressive advertising caused a legal dispute with [[Agfa]] about the definition of the term ''fully automatic''. [[Braun]] lost the case and had to commit themselves not to use the phrase ''First fully automatic camera'' anymore.<ref name="Zellner"> Walter Zellner ''Die Kameraherstellung bei Carl Braun in Nürnberg'' (2004, Selbstverlag)</ref>
 +
 
 +
The camera obviously was launched on the market a bit pre-mature which can be can be attributed to the fact that there are 3 variants differing in small details, all of which have their own Kadlubek number (BRA1065, BRA 1066, BRA1070).<ref name="Knipps1">[https://knippsen.blogspot.com/2023/11/braun-paxette-electromatic.html Electromatic I] on [https://knippsen.blogspot.com KniPPsen].</ref>
 +
 +
The first variant can be recognized in particular by the rewind (unlock) button, which is located directly behind the shutter button on the top of the camera and can be easily mistaken with the latter.
 +
 
 +
For variant 2, Braun elegantly transformed the rewind button into an inconspicuous rewind slider, which can now be found on the back of the camera, just a few millimeters away from the original location. This second variant also now has a printed warning on the film pressure plate (see picture) that actually only 17 or 18 DIN films can be used.
 +
 
 +
Only the third variant, launched in spring 1960, got rid of the limitation of only one film speed. There is now a small slider at the bottom right of the lens, labeled 16-18-21 DIN, or 10-32-64 ASA in the export version. Interestingly, this is not technically the same, but probably reflects the types of films most commonly available in the respective markets. This was achieved using an "improved" shutter that now controls three speeds (est. 1/40, 1/60 and 1/120 s)<ref name="Zellner"></ref>, which are not officially documented anywhere else. This variant was renamed '''Paxette electromatic I''' in the course of 1960, but you can also still find examples with only '''electromatic''' engraved on the cap.
 +
 
 +
The (fixed) lens was mostly an Ennagon 5.6/40 mm, a coated triplet, made by [[Enna]]. The later variants can also be found with a Katagon made by [[Staeble]] (same specification). The camera has a [[hot shoe]], a rare feature for its time, and actually was one of the first cameras re-introducing it to the market as future standard.

The Electromatic II still had a single shutter speed at 1/40 sec, but with an improved lens. It was fitted with an Ultralit 1:2.8/40mm, focussed with a twist/screw action. Markings on the lens show that it can focus down to 1m (3.3 feet), although with only a simple viewfinder the photographer must use a [[guess focusing]] technique. At around 2m there is a symbol of a person to indicate portraiture, and at around 4m there is a symbol of a building. As with the Electromatic, the [[selenium meter]] gave a red/green light sufficiency signal.

The '''Electromatic II''' was a major upgrade compared to the original model which was continued as '''Electromatic I'''. It was fitted with an Ultralit 1:2.8/40mm made by [[Rodenstock]], focussed with a twist/screw action. Markings on the lens show that it can focus down to 1m (3.3 feet), although with only a simple viewfinder the photographer must use a [[scale focusing]] technique. At around 2m there is a symbol of a person to indicate portraiture, and at around 4m there is a symbol of a building.

Besides the lens, the most important improvement is the shutter, [[Gauthier]]'s '''Prontormat-S''', a so called "Lichtwertverschluss" (light value shutter). It is controlled by the [[selenium meter]] setting distinct shutter-aperture-combinations from 2.8, 1/30s (LV 8) to 22, 1/300s (LV 17). <ref name="Knippsen">[https://knippsen.blogspot.com/2023/11/braun-paxette-electromatic-ii.html Electromatic II] on [https://knippsen.blogspot.com KniPPsen]</ref> These are displayed at the top of the viewfinder. Insufficient light is signaled with a red flag. Besides this ''Auto'' setting the shutter can also be set to ''B'' and ''flash'' (1/30s). For both time settings the full set of apertures can be set manually. Interestingly, the hot-shoe from the original model was again replaced by just a standard flash (PC) socket.

==General Information==
 +
The entire '''Paxette electromatic''' series uses the same basic body, including a back made of bent sheet metal surrounding the camera, which can be loosened using a knurled screw around the tripod socket. The cameras are compact: width is about 111 mm, height 83 mm or 88 mm (models II and III), smaller than most competitive cameras. With a weight from 570 g (original model) to about 700 g (II and III) they are quite heavy. The solid film handling is also the same for all models and featured levers for both film advance and rewind! Interestingly, the models I and Ia need a double-stroke advance, while the advanced models II and III use a single stroke for film advance and shutter cocking. Outstanding for its time was the huge and bright viewfinder featuring a light frame, in case of the later models including parallax marks.

Apparently, all models used a single serial number range. The lowest numbers sighted are 397xxx, the highest 516xxx,<ref name="Knipps1"></ref> resulting in possibly 120.000 units made over a period from mid 1959 to February 1964.<ref name="Zellner"></ref> Most of these (approx. 60-70 thousand) can probably be assigned to the simple entry-level models which, with an attractive price, particularly appeal to the new target group of photographic laymen. Customers who already knew a little more about photography may have been put off by the fixed focus lens and the original camera's other limitations.
 +
In retrospect, Braun wasn't very successful: despite the significant price difference, customers preferred the actual fully automatic Agfa Optima (500,000 units in 2 years, for 238 DM). When Braun followed suit technically (electromatic II), there was already a lot of competition on the market (including [[Kodak Retina Automatic I II III|Kodak]], [[Vito Automatic|Voigtländer]], etc...) and it became even more difficult to survive.

The Paxette electromatic is a series of 35mm cameras produced by Braun from 1959 to early 1964. They all feature the same compact body, a built-in selenium meter and coupled with it a trap-needle exposure automatic. When launched in 1959 the original version was advertised as the world's first and only truly fully automatic 35mm camera causing a legal dispute with Agfa who launched its superior Optima a few weeks earlier. Despite the automatic aperture the original electromatic is a rather simple camera with a fixed focus lens and only one shutter speed and film speed setting. The later Paxette electromatic II (launched in 1960) has a better lens, manual focussing and fully automatic exposure setting, similar to the much more successful Optima. The Paxette electromatic III (launched in 1961) offers more manual control and shutter priority exposure automation. With the launch of the II and III models the original electromatic was rebranded as Paxette electromatic I and later succeeded by the model Ia, which is almost as simple but features an exchangeable lens.

Electromatic (I)

In 1959 the original Paxette electromatic was advertised as the world's first and only fully automatic 35mm camera. Its selenium meter controls the aperture and gives a green light sufficiency signal in the viewfinder. But other automatic functions are missing. Instead, the focusing of the Ennagon 1:5.6/40mm lens is fixed, and it has only the single shutter speed 1/40 sec. Even film speed is fixed and only film with 17/18 DIN (40/50 ASA) can be used. The aggressive advertising caused a legal dispute with Agfa about the definition of the term fully automatic. Braun lost the case and had to commit themselves not to use the phrase First fully automatic camera anymore.[1]

The camera obviously was launched on the market a bit pre-mature which can be can be attributed to the fact that there are 3 variants differing in small details, all of which have their own Kadlubek number (BRA1065, BRA 1066, BRA1070).[2]

The first variant can be recognized in particular by the rewind (unlock) button, which is located directly behind the shutter button on the top of the camera and can be easily mistaken with the latter.

For variant 2, Braun elegantly transformed the rewind button into an inconspicuous rewind slider, which can now be found on the back of the camera, just a few millimeters away from the original location. This second variant also now has a printed warning on the film pressure plate (see picture) that actually only 17 or 18 DIN films can be used.

Only the third variant, launched in spring 1960, got rid of the limitation of only one film speed. There is now a small slider at the bottom right of the lens, labeled 16-18-21 DIN, or 10-32-64 ASA in the export version. Interestingly, this is not technically the same, but probably reflects the types of films most commonly available in the respective markets. This was achieved using an "improved" shutter that now controls three speeds (est. 1/40, 1/60 and 1/120 s)[1], which are not officially documented anywhere else. This variant was renamed Paxette electromatic I in the course of 1960, but you can also still find examples with only electromatic engraved on the cap.

The (fixed) lens was mostly an Ennagon 5.6/40 mm, a coated triplet, made by Enna. The later variants can also be found with a Katagon made by Staeble (same specification). The camera has a hot shoe, a rare feature for its time, and actually was one of the first cameras re-introducing it to the market as future standard.

Electromatic II

The Electromatic II was a major upgrade compared to the original model which was continued as Electromatic I. It was fitted with an Ultralit 1:2.8/40mm made by Rodenstock, focussed with a twist/screw action. Markings on the lens show that it can focus down to 1m (3.3 feet), although with only a simple viewfinder the photographer must use a scale focusing technique. At around 2m there is a symbol of a person to indicate portraiture, and at around 4m there is a symbol of a building. Besides the lens, the most important improvement is the shutter, Gauthier's Prontormat-S, a so called "Lichtwertverschluss" (light value shutter). It is controlled by the selenium meter setting distinct shutter-aperture-combinations from 2.8, 1/30s (LV 8) to 22, 1/300s (LV 17). [3] These are displayed at the top of the viewfinder. Insufficient light is signaled with a red flag. Besides this Auto setting the shutter can also be set to B and flash (1/30s). For both time settings the full set of apertures can be set manually. Interestingly, the hot-shoe from the original model was again replaced by just a standard flash (PC) socket.

The film speed is set by a small wheel on top of the camera (between 10-400 ASA, or 11-27 DIN). It actually turns the entire spool of the meter, which is located below it.

There is also a slimmed-down version called Electromatic IIs, which has the well-known fixed focus 5.6/40 mm lens, but otherwise the same functionality as the II.



Electromatic III

The later model (1961) electromatic III is still an automatic camera, but rather focussing on the amateur photographer who still wanted to have some manual control. The shutter is the Prontormatic from Gauthier with shutter speeds from 1/30s to 1/500s and B. In Auto setting the aperture is set by the meter (shutter priority automatic), but there is also the option for full manual control. The lens is the same as with model II.

Electromatic IA

The electromatic IA was launched in 1962 and replaced the "I". It has the same simple shutter and again the hot-shoe. Its main new feature was interchangable lenses through a proprietary lens mount. Only two lenses were available. Besides the standard lens Trinar 40 mm f/2.8 there is a Rotelar 75 mm f/4, both made by Rodenstock. [4] There were frames in the finder for both lenses. The camera was sold for 189 DM, the extra tele-lens for 99 DM.

In retrospect, Braun wasn't very successful: despite the significant price difference, customers preferred the actual fully automatic Agfa Optima (500,000 units in 2 years, for 238 DM). When Braun followed suit technically (electromatic II), there was already a lot of competition on the market (including Kodak, Voigtländer, etc...) and it became even more difficult to survive.
