From the editor

Rigid Summar 50mm F/2. For information about this lens, please refer to a page dedicated to the collapsible variant.

Notes

  • All LEICA lenses having a focusing lever are automatically locked at the infinity position. This feature enables the camera to be used for infinity scenes and subjects without danger of the lens becoming accidentally out of focus due to unintentional movement. To release the lever for focusing on nearer planes press the knob at the end of the lever.

FIKUS / 12530 (1933-1965)

Extendable hood for lenses of focal length 3.5cm to 13.5cm. Outer black sleeve slid over the nickel or chrome graduated sleeve and was locked in position by a set screw. The black lower collar carried the usual clamping ring and screw. Early ones nickel inner sleeve, later ones chrome. Leitz, New York also made an all chrome version. Many variations in engravings: e.g. four focal lengths 13.5cm, 9cm, 5cm and 3.5cm with "Hektor" to the left and "Elmar" to the right of the scale; three focal lengths only with no 3.5cm and only "Elmar" to the left; 13.5, 9 and 5 with two positions for the 5, the lower one having "Hektor" to the left and "Summar" to the right.
