One of the oldest lens mounting technologies is surprisingly simple, a thread. Leica would be the first with the Leica Thread Mount or M39 as it became known in the 1930s with the Leica I (C), in the 1940s Zeiss Ikon would put forward a much larger diameter thread mount, known as the M42. The camera would be the Contax S and marked the start of the modern SLR. Eventually, the M42 mount would take on additional names like Universal screw mount, Pentax screw mount, and Praktica screw mount. In this episode, the gang takes on some of their favourite screw mount cameras. Cameras FeaturedRead More →
