Filmosto
Filmosto was founded in 1924 in the optical industry in Dresden . Filmosto specialized in projection technology ( slide projectors , projection lenses). Through VEB Aspecta Dresden, Filmosto is one of the founding companies of VEB Pentacon Dresden, which was established in 1964 . Filmosto and later ASCOP also produced slide series and film tapes.
history
Müller & Wetzig
In 1899 Johann Wetzig and Robert Müller founded a "special factory for projection and magnifying devices". They manufactured projection, enlargement and cinema equipment, including the "Dresdensia" projection apparatus (1903, lens by Emil Busch ), the projectors I to V (from 1905) and the Fam VI enlarger (1935). In 1937 the delivery directory for vertical enlargers with manual focus included the series Pollux , Artus VIII and Artus X as well as Sirius . Fix and Phönix I , Phönix III and Phönix V had automatic focusing . Horizontal enlargers were Orion , Matador , Effekt, and Saxonia . The devices could process negatives from 6.5 × 9 cm to 18 × 24 cm. Double anastigmats were consistently offered as lenses for the devices . There were also enlargers for smaller formats and the multifoc universal device .
In 1938 the sons of the two founders, Georg Wetzig and Willy Müller, took over the company, which was completely destroyed in 1945. After a few difficulties, however, production was resumed as early as 1946 under the new company name M&W enlargers , and so during this time - with a nameplate made up of the two letters M and W - among other things: Manufoc enlargers were manufactured. With the nationalization that took place in the same year, however, the company was renamed the VEB enlarger factory shortly afterwards , and finally merged with VEB Filmosto-Projektion Dresden in 1956 (see below).
Filmosto projectors Johannes Jost
In 1924 the Filmdienst Jost & Co. KG was founded in Dresden , which was renamed Filmosto-Projektion GmbH in 1932 and finally in 1937 Filmosto-Projektoren Johannes Jost . The company's products were, on the one hand, illustrated books and, on the other hand, the two slide projectors Aladin and Bube . In the course of the conversion of the German economy to war production in World War II , the company manufactured parts for radio equipment from 1940. In February 1945 the company was largely destroyed, so that after the end of the war only household items and projectors (the latter as reparations) could be manufactured.
Filmosto Ost - VEB Aspecta - VEB Pentacon
In 1948 Filmosto was expropriated and renamed Mechanik Filmosto-Projektion VEB Dresden , while the production of image films was taken over by the company Strahlbild - Distribution ASCOP Werner Nowak . In a transitional period, the Filmosto photo books were also published with the manufacturer's specification Strahlbild-Verlag "Filmosto" - Dresden (later DEWAG ).
In 1951, the optical plant was renamed VEB Filmosto Dresden , whereupon the previous owner Johannes Jost left the company. In the same year was Filmosto the VVB assumed optics and now operated under the name optical Filmosto projection VEB Dresden .
In 1953, a recent name change, now VEB Filmosto projection Dresden , from 1956 through merger with the 1946 from Müller & Wetzig OHG emerged enlargers factory VEB of VEB Aspecta Dresden emerged.
But two years later, in 1958, this company was merged again with two other companies, the VEB Kamerawerk Niedersedlitz, founded in 1953, and the VEB Camera and Kinowerk Dresden , founded in 1958 , to form the VEB Camera and Kinowerk Dresden , which from 1964 became VEB Pentacon Dresden was named .
The former Filmosto factory at Pestalozzistraße 12 in Dresden ( Johannstadt Süd ) was used after the reorganization of production as "Object 15" for Pentacon's polytechnic lessons .
Filmosto West
In 1952, the former owner of the Dresden main plant Johannes Jost founded a new Filmosto operating in food, the Filmosto projection John Jost GmbH & Co . Technologically also further innovative, for example, between 1978 and 1988 it was granted at least four US patents for picture holders, devices for framing slides and containers for photographs, submitted by Jochen F. Jost, among others.
Products
Projectors
The very early slide projectors from the 1920s only had the type designations A and B.
Jack
The jack was made at least until about 1938. The Bube 100 was widespread and is now (2010) offered quite often as an antiquarian. The moderately bright Filmostar III 1: 3.5 / 100 mm served as a projection lens. In 1939 a slightly stronger Jack 150 was made.
Color box
Another early slide projector is the Filmosto Color Box z. B. with a projection lens Filmostar III 1: 4/100 mm.
Primascope
The Filmosto Primascope was available at the beginning of the 1950s . It was a projector for 35mm slides and film strips in a Bakelite housing. A normal 100 watt light bulb (E27) is used as the projection lamp. The primascope had a bifocal condenser. There was also a special lamp from Osram . In 1952 the cost with accessories was around 110 DM.
Filius
The “Filius” slide projector followed in the mid-1950s. Later VEB DEFA Gerätewerk Friedrichshagen took over the production of the Filius. The filius can also be found with projection lenses from Meyer-Optik (e.g. Diaplan 1: 3.5 / 100 mm or Trioplan 1: 3/100).
VB 250
The VB 250 , which was manufactured around the same time, had a metal housing and a significantly higher power consumption of 250 W. The VB 250 could also use 35mm slides and film strips. The device still had an external transformer ("current transformer"). For example, the Filmostar IV 1: 3/100 mm served as the projection lens.
Jubilee
The larger Filmosto Jubilar was also produced in the mid-1950s. This device can also be found with projection lenses from Meyer Görlitz , e.g. B. the Diaplan 1: 3.5 / 140 mm, the Diaplan 1: 3/100 mm or a Trioplan 1: 3/100 mm. In 1954, jubilee projectors with the brand name “Filmosto” were also manufactured by VEB Gerätewerk Friedrichshagen, Berlin.
Primalux
The Primalux projector was available for medium format slides up to 5 × 5 cm . A special diascope was also made.
Müller & Wetzig "Mag-Pro"
Müller & Wetzig manufactured the Mag-Pro with a Trinar anastigmat from Rodenstock as a projector.
Vivax
The VEB Aspecta brought out a Super 8 film projector called Vivax . With a 12 volt / 50 watt lamp, the device was not very bright, but less demanding amateurs in the GDR considered it a "solid and elegant" device.
Episcopes
As Episkop is Filmosto Episkop 500 documented.
Enlarger
In 1947, Filmosto began producing the Autofoc I enlarger , which had an automatic focus setting. The Mueller & Wetzig company (taken over by Filmosto in 1951) manufactured enlargers (Multifoc I, II and IIA) under the brand name Multifoc . And later there was also a model called Multifoc III, year of manufacture unknown, whose shelf allows the enlargement of 9 × 12 cm negatives.
Filmosto will continue to manage the products after the merger with Mueller & Wetzig. For example, the Autofoc II , the Autofoc II B / W , which could enlarge up to 4 × 4 cm negatives, or the Autofoc IIA for medium format negatives from 6 × 6 cm to 6 × 9 cm were sold. As a projection lens all three versions of the served Autofoc II a Helio plan lens 1: 4,5 / 55 mm of Meyer optics . The Autofoc III , produced around 1954, had an automatic focus setting for negatives up to 6 × 6 cm.
Another, compact enlarger, specifically for 35mm negatives, had the brand name Adjutar , equipped with an Orthan lens 55 mm f / 4.5 mm from the Rathenower Optical Works .
Projection lenses
Filmosto manufactured a line of projection lenses known as Filmostar . The individual types were marked with Roman numerals from the Filmostar II to the Filmostar IV. These are projection lenses of the Cooke triplet type . The pre-war models had a light intensity of 1: 4 to 1: 3.5, as was typical for Cooke triplets without lanthanum glass. Lenses of 75, 80 and 100 mm were produced at focal lengths.
Film star II
- Filmostar II, 1: 3/75 mm (manufacturer label: Hugo Meyer & Co - Görlitz )
Film star III
Examples:
- Filmostar III, 1: 3/75 mm (label f = 7.5 cm)
- Filmostar III, 1: 3.5 / 75 mm (label f = 7.5 cm)
- Filmostar III, 1: 3/100 mm (label F = 10 cm)
- Filmostar III, 1: 3.5 / 100 mm (label F = 10 cm)
Film star IV
- Filmostar IV, 1: 3/100 mm (label F = 10 cm)
Projection accessories and other optical devices and instruments
The slide viewer Filmosto Kieker , which was manufactured before the Second World War and was available for both 35mm and 6 × 6 medium format slides , was widespread . Müller & Wetzig had also made slide viewers. Additional accessories for slide projection were offered as slide mounts as well as manually labeled slides, e.g. for title slides. Filmosto also made magnifying glasses.
Projection media
In addition to projection devices, Filmosto also sold media early on, including both slide sets and so-called film tapes. It is a series of slides that have not been cut apart. The Filmosto media were later sold under the name ASCOP .
