Cameras played a major role in documenting the experiments and testing carried  out the early days of guided weapons development. A suite of specialised cameras were developed in the mid- to late 1950s by various U.S. manufacturers, by Soviet camera makers and by the Royal Aircraft Establishment in the UK.
 
−
 
 
−
In Australia, the [[WRE | Weapons Research Establishment]] (South Australia) designed such cameras as part of the  Anglo-Australian Joint Project (1946 to 1980) which focussed on  guided weapons and missile development. The research focussed on  a missile's behaviour in flight relying on observation and  general telemetry data. While the latter would be displayed on an cathode-ray oscilloscope in real time, they needed  recording to allow for detailed analysis. Film was a suitable medium to record such transitory analog data. To this end, high-speed cine cameras were developed which capable of 100 frames/second and more. While recorded data would be viewed as segments of motion film many were analysed on a frame-by-frame basis.
 
−
 
 
−
In principle, cameras were developed for  four different applications: ground-based cameras for observation and the recording of the telemetry, and airborne cameras, either borne by the missile or carried by the target.

During the  early period of the Cold War the United Kingdom carried out wide-ranging missile research, partly in collaboration with Australia (under the umbrella of the Anglo-Australian Joint Project, which ran from 1946 to 1980). <ref>For background on the project see Morton, Peter (1989) <i>Fire across the desert. Woomera and the Anglo-Australian Joint Project 1946–1980.</i> Canberra: AGPS.—For general context of UK guided weapons development in the 1950s see Twigge, S.R.

The testing of the missiles required a range of sophisticated devices to record and document missile behaviour in flight, approaches to targets and also to record telemetry data that were obtained on the ground. In the days prior to digital data collection this occurred analog, with film being the preferred option.

All cameras carry the type specification GW for <b>G</b>uided <b>W</b>eapons. While technically most of the cameras where high speed cine cameras (100 frames/second), many of them were  used for  frame-by-frame analysis:
 
−
* [[Dekko GW 1|GW 1 Target Aircraft Camera]] (Dekko Ltd, 1954)-- a high-speed 35mm cine camera mounted in the target aircraft to record the missile approach angles (and miss distances).
 
−
* [[Beck GW 2|GW 2  Target Aircraft Camera]] (Beck, 1955)-- a high-speed 35mm cine camera mounted in the target aircraft to record the missile approach angles (and miss distances).
 
−
* GW 3 Continuous Record Camera (Cinetra Ltd, 1958). The GW3 was a high-speed 35mm cine camera developed to record cathode ray oscillograph images at various speeds.<ref> The camera was jointly developed by the Royal Aircraft Establishment  and Cinetra Ltd. It took 200ft rolls of daylight loadable 35mm cine film. The design had a geared advance that allowed for recording speeds of 1 inch/sec  to 128 inches/sec. The camera came with three interchangeable lenses (1 ¼", 2" and 3") all with f/1.9. A time marker unit was also fitted.-- For details and specifications, see: Brooks, J.H. (1958) Type GW 3 continuous record camera. (UK National Archives AVIA 6/23834).</ref>
 
−
* GW 9 Missile Camera (Specto  Ltd, 1960)—A 16mm high-speed cine camera with interchangeable lenses, carried by missiles in flight.<ref> The 16mm camera, running at 100 frames/sec, was designed and built by Specto Ltd, (London. Specto were manufacturers of cine cameras and projectors, operating from 1935 to 1960 ([http://wichm.home.xs4all.nl/cinelisc.html list of manufacturers of vintage cinematographic equipment]). --The GW 9 came with four Specto Ltd. lenses (1/2” f/4; ¾, f/4.5; 1 ½”, f/1.9 and 3’, f4). In addition, it could accept lenses designed for the G.S.A.P. cameras. The camera used a circular disc shutter with two sectors cut out of the rim. At 100 frames/sec the shutter speed was 1/210th. The 50ft of daylight loadable 16mm film allowed for 20 seconds of running time.--For details and specifications, see: Husbands, C.W. (1960) The type GW 9 missile camera. Royal Aircraft Establishment Technical Note TD47, March 1960. London: Royal Aircraft Establishment (Farnborough), Ministry of Aviation (UK National Archives AVIA 6/23847).</ref>

In Australia a number of similar cameras were built which carried different designations: WRECISS, [[WREROC]] and [[WRETAR]].

[[Helios]]-44 (Гелиос-44) is a series of standard lenses for SLR cameras, produced from 1949? until 1992 (2001?) in the Soviet Union by [[KMZ]], [[MMZ]], and by [[Valdai]]. The Helios-44 is it is considered to be one of most mass-produced lenses in the world. The lens is based on the [[Carl Zeiss]]  Biotar f/2 58mm design.<ref>At the beginning the lens was to be called "БТК" - "БиоТар Красногорский" (BioTar Krasnogorski).</ref> The Helios-44 f/2 58mm is a  6-element anastigmat, which over the duration of its production  was available in both single-coated and multi-coated versions. Helios-44 is has a strong aberration at the margins, resulting in a characteristic 'swirl' which is reminiscent of [[Petzval]] lenses.

The nomenclature of all bar the first (silver-cased) Helios lenses follows the formula 'Helios-44X-N',  where X -is the index of lens mount (M for [[M42]] thread, K for [[K mount | Pentax K]] bayonet, Д for [[Zenit]]-D bayonet) and N is a optical resolution index 2, 3, 4, 5, 6, 7 (the higher number the higher is an optical resolution of lens).

While technically a high speed cine camera, shooting at 100 frames/second, the  resulting negatives were not projected as a film but examined individually in order to assess the miss distance of the missile in relation to its target.
 
−
The film magazine took a standard 50ft roll of 35mm cine film, which gave the camera a run time of 12 seconds.

===Mk 1A===
+
The early Helios lenses are housed in aluminium barrels. Reputedly, the serial numbers of the early Helios lenses are structured according to the following pattern:<ref>[http://forum.mflenses.com/a-word-about-russian-serial-numbers-t3332.html | A Word about Russian Serial Numbers]</ref><br>
 +
000xxxx factory test (study) models, prototypes etc..<br>
 +
00xxxxx models reserved for members of the communist party and other "VIPs" .<br>
 +
0xxxxxx reserved for factory syndicat leaders.
 +
All lenses with a '0', '00' and '000' prefix reputedly underwent higher quality control.
  
 +
Additional variations exist in the representation of the serial number prefixes. Observed have been <b>N</b> and <b>N&#186;</b>, whereby the 'N" appears on some of the earlier models.
 +
=====Helios 44 (Start)=====
 +
Mechanically, the Helios lens for the [[Start]] SLR differs from all other Helios-44 lenses inasmuch as the focussing ring is up front and the aperture selector at the rear. Moreover, the lens for the Start lacks the preset function of the other early models. Aperture selection with f-stops increasing in clockwise motion.

There is no readily visible difference between the Mk1C and Mk1D models, either in overall appearance, lenses or mechanics.

Helios-44 (Гелиос-44) is a series of standard lenses for SLR cameras, produced from 1949? until 1992 (2001?) in the Soviet Union by KMZ, MMZ, and by Valdai. The Helios-44 is it is considered to be one of most mass-produced lenses in the world. The lens is based on the Carl Zeiss Biotar f/2 58mm design.[1] The Helios-44 f/2 58mm is a 6-element anastigmat, which over the duration of its production was available in both single-coated and multi-coated versions. Helios-44 is has a strong aberration at the margins, resulting in a characteristic 'swirl' which is reminiscent of Petzval lenses.

The nomenclature of all bar the first (silver-cased) Helios lenses follows the formula 'Helios-44X-N', where X -is the index of lens mount (M for M42 thread, K for Pentax K bayonet, Д for Zenit-D bayonet) and N is a optical resolution index 2, 3, 4, 5, 6, 7 (the higher number the higher is an optical resolution of lens).


Technical Specifications

Focal Distance: 58mm (may vary in reality).
Aperture Range: ƒ/2 - ƒ/16 (ƒ/22)
Optical Formula: 6 elements in 4 groups.
Angle of View: 40°28
Geometric Vignetting: 58%



The arrangement of the focussing helicoid as well as the aperture selector ring differs between models. In the table below, the arrow ← indicates the direction the aperture control ring needs to be turned to increase the ƒ-stops.

Typology of the silver-barrelled Helios-44 lenses (early versions)

The early Helios lenses are housed in aluminium barrels. Reputedly, the serial numbers of the early Helios lenses are structured according to the following pattern:[5]
000xxxx factory test (study) models, prototypes etc..
00xxxxx models reserved for members of the communist party and other "VIPs" .
0xxxxxx reserved for factory syndicat leaders. All lenses with a '0', '00' and '000' prefix reputedly underwent higher quality control.

Additional variations exist in the representation of the serial number prefixes. Observed have been N and Nº, whereby the 'N" appears on some of the earlier models.

Helios 44 (Start)

Mechanically, the Helios lens for the Start SLR differs from all other Helios-44 lenses inasmuch as the focussing ring is up front and the aperture selector at the rear. Moreover, the lens for the Start lacks the preset function of the other early models. Aperture selection with f-stops increasing in clockwise motion.

  • Type 1— f-stops to f/22; bezel text that spells out '1:2 F=5,8cm' with a Cyrillic P (Π) in red, silver front bezel ring. Released 1958.[6]
  • Type 2— f-stops to f/16; bezel text "2/58" and the 'silver' front bezel ring produced by KMZ [7]
Helios-44 (LTM)

Pre-set prime lens. The fixed lens stops have with audible clicks, while the stop-down ring (to check the depth of field) allows for a smooth contraction of the diaphragm. Aperture selection with f-stops increasing in counter-clockwise motion (differs from the Helios version used on the Start)..

  • Type 1—pre-set lens with f-stops to f/22; bezel text that spells out '1:2 F=5,8cm' with a Cyrillic P (Π) in red, silver front bezel ring, sn 000xxxx–0017xxx. Initially used for the KMZ Kristall released in 1961 and the KMZ Zenit 3M.
  • Type 2— pre-set lens with f-stops to f/16
Type 2a—bezel text that spells out '1:2 F=5,8cm' with a Cyrillic P (Π) in red, and a silver front bezel ring, sn 0016xxx [8]
Type 2b—bezel text "2/58" and the 'silver' front bezel ring produced by KMZ
Type 2bi— Cyrillic labelling, ring, sn 0073xxx– [9]
Type 2bii—Latin labelling
Type 2biii—Latin labelling, engraved "Made in USSR'. [10]
Type 2c—bezel text "2/58" and 'black' front bezel ring, 13-blade diaphragm produced by KMZ until the late 1950s, sn –0225xxx
Type 2ci— Cyrillic labelling[11]
Type 2cii—Latin labelling [12]
Type 2ciii—Latin labelling, engraved "Made in USSR'. [13]

Type 2di—Cyrillc labelling, [14]
Type 2di—Cyrillc labelling, engraved "Made in USSR'. [15]
Type 2diIi—Latin labelling, engraved "Made in USSR'. [16]
