what is a leica lens
The first Leica lens was a 50 mm f/3.5 design based on the Cooke triplet of 1893, adapted by Max Berek at Leitz. The lens had five elements in three groupsâthe third group being three cemented elementsâand was initially called the Leitz Anastigmat.n addition to the 50mm normal lens, a 35mm wide angle and a 135 mm telephoto lens were initially available. In the mid-1930s, a legendary soft-focus lens, the Thambar 90mm f/2.2 was designed, and made in small numbers between 1935 and 1949, no more than 3000 units. It is a rare collector's item today.
