Manufacturer description #1

The standard Leitz Elmar F: 3.5, 50mm. (2"), coated lens has a light transmitting power sufficient for most exposures. The correction of this lens has been so thoroughly carried out that its performance at F:3.5 with regard to definition is extremely good. The Leitz Elmar yields a sharp image at full aperture and covers the whole negative field perfectly. Because of its remarkable optical construction, and relatively large aperture, this lens will always remain the most suitable for the majority of amateurs and is therefore one of the "Standard Lenses" for the Leica camera.

This standard lens, the Leitz Elmar, has now been made for more than 25 years, and has achieved an excellent reputation. It is provided with changing flange for alternative use on the camera, enlarger or projector, and may also be used in conjunction with the auxiliary devices for photographing small objects.

Manufacturer description #2

In its assembly, the Elmar 50mm., f/3.5 (2") angle of view 45 deg., constitutes a known triplet variant consisting of three members. The last member contains a converging cemented surface, and, under favorable correction conditions has a relatively simple construction. The correction possibilities of this type of system have been widely utilized, and all residual defects, chromatic as well as spherical, are adjusted to each other so that an especially favorable general correction adapted to the Leica format is obtained. The sharpness increases rapidly as the aperture is reduced, and at f/8 it is at its maximum.

From the editor

From No. 905,000 improved optical design using same basic Elmar construction, but different optical glasses, recognized by a noticeably flatter curvature of the front element. Depth of field scale in red for a time.

Notes

• LEICA lenses HEKTOR 28/6.3, ELMAR 35/3.5, HEKTOR 50/2.5, ELMAR 50/3.5 [I], [II] have the aperture scales engraved on the front of the lens mount. The iris is opened and closed by adjustment of a small finger-piece engraved with an index line. On all other LEICA lenses the diaphragm is controlled by means of a milled ring.
• 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.
