The Beseler Topcon B Autokinon  

The Beseler Topcon B was the first single lens reflex camera manufactured by Tokyo Kogaku for export. Identical to the Topcon R, except for the faceplate, it was introduced in 1957 and was the first Japanese SLR with a semi-automatic diaphagm. In 1959, fully automatic external diaphragm stopdown (Autokinon) lenses were introduced. A fine export example is shown here with the Tokyo Kogaku 5.8cm f1.8 Auto Topcor (Autokinon) lens. The Topcon B is the most frequently encountered export early Topcon SLR however, pristine ones are getting rather uncommon. With the Autokinon lens, they are quite rare.
