Leica III (Model F)
1933 - 1939
In 1933 the Leica III (Model F) was introduced. It had slow shutter speeds, ranging from 1 second to 1/20th second, besides the usual speeds from 1/20th to 1/500th second, an enlarged and improved field of view for the automatic range finder, and metal eyelets on the camera case for a neck-strap by means of which it may be suspended from the neck or shoulder without the aid of the carrying case.
The automatic range finder on the Model F Leica is endowed with a magnifier which produces an enlarged image. The image seen is 1 1/2 times magnified over that seen in the range finder of the Model D. The field is clear over its entire area, whereas in the Model D it is pale yellow, with a white disc in its center, by means of which the two images are coincided for sharp focus of the camera lens.
An adjustable eye-piece is provided on the range finder of the Model F by means of which accurate registration of the image is secured at all distances from three feet to infinity.
