Depth of Focus

This is the Kodak Reflex, a genuine twin lens reflex camera manufactured by the Eastman Kodak Company from 1946 to 1948. It makes twelve 2 1/4" x 2 1/4" (6 x 6cm) images on 620 roll film. The Reflex was superseded by the Reflex II with minor changes from 1948-49.  Kodak isn't normally a company we associate with TLR cameras. Indeed this camera, and its successor the Reflex II, are the only true TLR cameras that Kodak ever manufactured. They also made pseudo-TLR cameras, such as the Brownie Reflex  or Brownie Starflex , but these are simple box cameras with oversized reflective finders, not cameras with a focusing screen.  The modern twin lens reflex camera (a camera with two lenses, one used for focusing on a screen and one for taking the image) owes much of its origins to  Franke & Heidecke in Germany, who developed the design we are familiar with today. Most twin lens reflex cameras following the Rolleiflex model take twelve  2 1/4" x 2 1/4" images, have

    Part 1: History      The name Kodak, while familiar to any photographer, is not one normally associated with high-end photographic instruments. Indeed, one of the philosophical principles first put forward by George Eastman is the vast distribution and use of inexpensive snapshot cameras, the use of which ensured the continued sale of Kodak film. This philosophy has been associated with the Brownie cameras and exacerbated by the Instamatic cameras of the 60s and 70s, perhaps unfairly branding Kodak with the reputation that they were only ever capable of building low quality cameras. However, if one is observant of history it will be apparent that there are several Kodak cameras which challenge this assertion. These examples originate from an era of approximately 1936 to 1956 in which American photographic manufacturing was given a brief opportunity to compete on the world stage against foreign competition. The looming and destructive war in Europe and Asia, gave American manufactur
