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 Leica Summicron-M 50mm f2 for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. Leica Summicron-M 50mm f2 is the longer of the two lenses at 44mm. The Leica APO-Summicron-M 35mm F2 ASPH with a length of 41mm, is 3mm shorter. On the other hand, there is no difference between the max diameters of these lenses, both coming at 53mm.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Leica Summicron-M 50mm f2 weighs 240g, 25% (80g) lighter than the Leica APO-Summicron-M 35mm F2 ASPH's weight of 320g.
