The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summicron-M 50mm f2 and the Leica Summicron-M 35mm f2 ASPH 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 Summicron-M 35mm f2 ASPH with a length of 35mm, is 9mm 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, which means it is 15g (5%) lighter than the Leica Summicron-M 35mm f2 ASPH which has a weight of 255g.
Filter Threads
Both the Leica Summicron-M 50mm f2 and the Leica Summicron-M 35mm f2 ASPH have the same Filter thread size of 39mm.
Below are links to the 39mm filters that we recommend you to consider for these lenses:
