This is a 1950s folding camera made by Barnet-Ensign. It features a 100mm 'Ensar' f4.5 Anastigmat lens, and uses type '20' film to produce 2.25" x 3.25" negatives.
The German made Voigtlander Vitoret was introduced in 1963, shortly before Voigtlander was taken over by Zeiss Ikon. The Vitoret was manufactured until the early 1970s when Voigtlander was sold on to Rollei.
The Rolleiflex TLR (twin lens reflex) medium format range was introduced in 1929, and continued with comparitively minor changes until 1993. The Rolleiflex T (which I have) was released circa 1962.
The Purma Special was introduced in 1937 and manufactured until 1951. This was a particularly unusual-looking bakelite camera, featuring a unique shutter and lens mechanism. The lens was spring loaded, being pushed back into the camera when the lens cap was replaced; preventing the photographer from making an exposure whilst the cap was on.
This camera was introduced in 1971. It featured match needle metering, depth of field preview, and was the last camera I purchased which used screw-mount lenses.
The Pentax S1 was manufactured from 1961 - 1966. Before this one landed in my hands, it was used for several years by my father to capture the tears and joy of Formula One motor racing around Australia.
