This article contains a list of the screw mount Leica models, from the early 1913 Ur-Leica to the Leica Ig from 1960, the last screw mount model. Brief descriptions and images from official Leitz brochures are included.
A parcel from Berlin today brought a remarkable Leica III with even remarkable Elmar 5cm 3.5 lens, and a chrome VIDOM viewfinder. It has a 5-digit serial number and was made in 1928!
Over the years I shot many Leica cameras. I loved them all but in the end I had to admit that one model really stole my heart due to its unprecedented simplicity: the early Leica II. But, what are nice screw mount lenses to use with that Oscar Barnack designed camera?
Some time ago, I suddenly was certain I needed a trigger winder on my 1938 Leica IIIa. Not having a transport lever on the camera made it a bit slow in use when I am shooting in the streets.
The Leica-made trigger winder is in fact a trigger bottom plate. It takes the place of the normal bottom plate, it has a spring to make the trigger return and that construction has one flaw: the trigger is connected to the film winder axle with the spring by means of a silk ribbon. And these ribbons sooner or later always snap.
The Tower type ’45’ camera was a screw mount Leica clone built by Nicca from Japan. It was sold exclusively by Sears in the United States, who commissioned cameras with their ‘Sears’ brand name with various Japanese and German camera manufacturers in the late 1950s and 1960s.
The second half of the 1950s saw the Japanese camera manufacturers face some difficulties in their production. Many of them (Canon, Nicca, Leotax, even the British Reid & Sigrist) had built their empires on copying the German design of the Leica IIIc. The Germans had lost their patents after World War II and the Japanese and other manufacturers had jumped on the opportunity to create their own versions of what had proven to be very well-built and highly effective cameras. But then, the Germans took the market back by releasing the Leica M3, which was a whole new level of camera and it was patented again too! The Japanese copy-cats were left lightyears behind.
But, they quickly figured out that Leitz had filed for a combined patent of all new features and had not filed the single alterations and improvements for patent too. And they set out to close the gap between their own (very capable!) models and the Leica M3.
And it got us some interesting developments.
