note is that the camera could be fitted with two types of register
Within this range of cameras, there are various Mk's, they were designed for high-speed, low-altitude, oblique reconnaissance photography. In order to overcome image movement under these conditions, high shutter speeds combined with a rapid rate of shutter firing and film transport were embodied in the camera systems.
The Mk.1, 2, 3, 4, 5 & 6 could be fitted with either a 4 inch or a 12 inch lenses
Mk.7 could be fitted with 3 inch or 6 inch lens
Mk.10 fitted with either a 1.5 inch or 3 inch lens. Also this Mk had IMC (Image Movement Compensation) system fitted.
The Mk.1 was fitted with a magazine that would give 475 exposures, the Mk7 could have either a magazine that gave either 500 or 1000 exposures and the Mk.10's magazine could give a total of 1200 exposures.
For all the Mk's the format of the film was 70mm wide, perforated along each edge and with a 2.25 inch square image area.
Designed for medium to high level daylight reconnaissance.
Could be fitted with 6, 12 or 48 inch lenses.
Could be fitted with 12, 24 or 48 inch lenses.
Both Mk's could be fitted with 250 or 500 feet magazines, giving 215 or 430 exposures
Film format was 9 inch x 9 inch.
Camera weight was approximately 61kg
|The camera was used in Canberra PR9 and a PR3 fitted for trials at aircraft testing centre at Boscombe Down, also the Percival Pembroke, Puma and Wessex helicopters. There were reports of one being fitted in the oblique mode in a Handley Page Hastings.|
This camera was designed for night photography at altitudes between 400 and 2,000 feet.
The camera is virtually two cameras in one. Illumination for the exposures was provided by 1.5 or 1.75 inch photoflash cartridges, which were ejected automatically from a discharger at regular intervals, giving an effective exposure time of 1/50 second.
To understand the principle of this camera, imagine two night cameras arranged in an aircraft to photography the same strip of ground.
If the shutters are operated alternately at regular intervals, the flashes can be arranged to explode at regular intervals so that the first exposure of one camera overlaps the first exposure of the other camera by 50% and so on throughout the whole photographic run.
Fitted with a 5 inch lens, image format was 5 inch x 4.5 inch and the camera was fitted with a magazine which could hold 100 feet of film, giving 480 exposures.
Use by the both the Canberra PR7 and the PR9 and also fitted to the Avro Shackleton.
