The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica APO-Summicron-M 35mm F2 ASPH and the Voigtlander 35mm F1.4 Nokton for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is an important deciding factor when comparing two lenses. Leica APO-Summicron-M 35mm F2 ASPH is the longer of the two lenses at 41mm. The Voigtlander 35mm F1.4 Nokton with a length of 29mm, is 12mm shorter. On the other hand, the Voigtlander 35mm F1.4 Nokton has a larger diameter of 55mm compared to the Leica APO-Summicron-M 35mm F2 ASPH's 53mm diameter.
The weight of a lens is as important as its external dimensions, especially if you are planning to hand hold your camera and lens combination for longer periods. Voigtlander 35mm F1.4 Nokton weighs 200g, 37% (120g) lighter than the Leica APO-Summicron-M 35mm F2 ASPH's weight of 320g.
