The Coronet Camera Company was an English company most noted for its box cameras manufactured in the 1950s. The company was established in 1926 at 48 Great Hampton Street, Aston, Birmingham, by Frederick Pettifer.
The Coronet Twelve-20 - a box camera taking 6x6 cm format pictures on 120 film and 620 film. There were two models, the basic and the Colour Filter Model - which had a green filter. Two aperture settings, f/16 and f/22; focus from 7' 0" to ∞ at f/22, or 8’ 6″ to ∞ at f/16; two shutter speeds, either around 1/25 s – 1/50 s, or bulb.
In the main, Coronet produced budget cameras. They remain common and can be cheaply obtained on the second hand market.
