Este es el primer objetivo intercambiable para la Leica, luego vinieron los de 90 mm y 135 mm. El paso de 50 mm a 35 mm (45º a 64º) representa un salto cualitativo, y esta distancia focal ha perdurado como uno de los pilares de la fotografía con cámaras Leica.

This is the first interchangeable lens that Berek designed for the Leica, a year later followed by the 90mm and 135mm. It is also used in the Stereo attachment. It is a classical Elmar construction, but now the aperture is located behind the second element.

The performance is typical for the modest lens layout with only four elements. Contrast is low at full aperture, but definition improves when stopping down.

One should relate the performance to the period in which the lens was designed, manufactured and used. The introduction of the 35mm camera system had occurred only five years earlier and the widening of the angle of view from 45 degrees to 64 degrees represented an increase of 40%. We are nowadays spoilt with angles of view of 90 degrees and more, but in the early years of miniature photography a 35mm lens was an object of desire. This particular focal length has become a standard one for Leica photographers for more than 80 years.

The impressive pictures that Paul Wolff produced with this lens were made mostly stopped down and at the smallest apertures this lens is a commendable performer. It was a popular lens and sold in relatively large quantities: almost 45.000 have been allocated.
