Zeiss Ikon Contax III 1936-42
The Contax III (544/24) was essentially the same as the Contax II except it had an uncoupled selenium exposure meter built into the upper housing assembly. It originally sold for between £53.0.0 to £78.5.0 depending on the lens. This is equivalent to about £1650 to £3650 today (about $3300 to $7300) which made it a rather expensive 35mm camera. In 1938, Contax II models could be upgraded by the factory to Contax III specifications for £13 15s although no one has yet attempted to determine how many were done. This factor may account for the occassional Contax III serial number that actually matches a Contax II. It is not known whether the serial number was changed following a factory upgrade.
