The Hektor 1:1.9/73mm was the first attempt by Berek to design a high-speed lens with a moderate angle of field.

The triplet design however could not be stretched too much and admirable as the design might be in those days (in the 1930s a lens with a speed of 1:5.6 was common and the Ernostar with a maximum aperture of 1:2 was the exception), the general performance wide open was not impressive.

The Sonnar construction was the better option in those days and one wonders why Berek used the general Hektor design. The Hektor 2.5/50 mm and Hektor 1.9/73 mm are close relatives and perhaps economic reasons might explain the choice.

The Hektor 1:1.9/73 mm is a very-low-contrast-low definition lens, but its speed made pictures possible of low lit subjects that were impossible to create with other cameras. The significance of the lens lies in its ability to allow the Leica photographer to take nightlife- and theatre-pictures that were previously impossible to make. For this type of picture taking Leitz produced the new word ‘Leicagraphie’

With a price tag of RM 260 (1936) it was 3.5 times as expensive as an Elmar 3.5/50mm (RM 75) and the second most expensive lens in the Leica line-up, but still sold about 7500 units.
