OUR REF AEG/KGR. MORTIMER HOUSE, 37 to 41 MORTIMER STREET, LONDON, W.1. 18th May, 1935. FILES Messrs. Rolls-Royce, Ltd., DERBY. Dear Sirs, We thank you for your esteemed enquiry and in our opinion our new Movikon 16mm camera would fulfil your requirements. The Movikon has provision for taking pictures at the rate of 12, 16, 24 and 64 per second, and by means of the adjustable sector shutter individual frames may be exposed as rapidly as in 1/1250th of a second. This exposure is arrived at when the taking rate is 64 pictures per second, and the shutter set to the narrowest sector, viz, 20°. The standard 1" Zeiss Sonnar fitted to the Movikon having an aperture of f {Mr Friese} /1.4 enables the operator to make full use of the adjustable shutter feature although of course when working on the higher speeds, bright illumination is necessary and also the use of a rapid film is suggested. In this latter connection, however, provided the film is properly developed in a fine grain developer, undue coarseness should be eliminated, but we would take this opportunity of mentioning that big enlargements of satisfactory quality from sections of 16mm film are, generally speaking, not obtainable, the largest size usually being about ¼-plate (4¼ x 3¼) to postcard size. We would also mention the Movikon can be used for single exposures and here again the adjustable shutter can be utilised, giving a range of speeds from 1/25th to 1/200th second. We agree the most satisfactory way of determining the suitability of the camera would be to make | ||
