the Berek designed 5cm Elmar lens in a Barnack designed lens mount<\/p><\/div>\n

Toronto<\/strong>. As you know, a camera needs a lens to capture an image. Leitz had just such a lens designer. In 1912 according to Dr Kingslake in his 1989 book, “A History of the Photographic Lens<\/a>“, a young Dr Max Berek joined the Leitz microscope company in Wetzlar. Max was “…devoted almost entirely to the theory of the microscope, in particularly the polarizing microscope used in mineralogy.”.<\/p>\n

A rather highly corrected sub-stage microscope condenser<\/a> was named after Berek. In the photographic world, Berek was of assistance to Oskar Barnack as the designer of the 5cm f\/3.5 Elmar<\/a>. According to Kingslake, “When the Leica camera was being developed by Oskar Barnack in the early 1920s, Berek designed several suitable lenses, including the Elmar, Summar, Summitar, and Hektor series.”<\/p>\n

The patent sheet above is for the lens mount designed by Barnack to house the lens designed by Berek. Some attribute the Elmar design to a variation of the Zeiss Tessar, but others note that at the time the Tessar design could not cover the inch by 1.5 inch (24 x 36mm) field of the Leica at f\/3.5 and suggest the Elmar is based on another fundamental lens design.<\/p>\n

Note: The title of this post is a riff on Paul Simon’s song, “You Can Call Me Al<\/a>” from his 1986 Graceland<\/a> album (I have the CD).<\/p>\n","protected":false},"excerpt":{"rendered":"
