The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summarit-M 35mm F2.4 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 Summarit-M 35mm F2.4 ASPH with a length of 34mm, is 10mm shorter. Besides being longer, the Leica Summicron-M 50mm f2 also has a larger diameter of 53mm compared to the Leica Summarit-M 35mm F2.4 ASPH's 52mm diameter.
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 Summarit-M 35mm F2.4 ASPH weighs 197g, which means it is 43g (17%) lighter than the Leica Summicron-M 50mm f2 which has a weight of 240g.
Below you can find the dimension and weight table of the Standard Prime Lenses in Leica M Mount for size comparison purposes.

Filter Threads
The Leica Summarit-M 35mm F2.4 ASPH has a filter size of 46mm whereas the Leica Summicron-M 50mm f2 has a 39mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 46mm filters that we recommend you to consider for the Leica Summarit-M 35mm F2.4 ASPH:
And these are the 39mm filters that we recommend for the Leica Summicron-M 50mm f2:
Lens Mounts
Both the Leica Summarit-M 35mm F2.4 ASPH and the Leica Summicron-M 50mm f2 has the same Leica M lens mount. Some of the latest released cameras that are compatible with the Leica M lenses are Leica M EV1, Leica M11-D and Pixii Max.
Focal Range
Leica Summarit-M 35mm F2.4 ASPH is a prime lens with fixed focal lenght of 35mm.
On the other hand, the Leica Summicron-M 50mm f2 is a prime lens with fixed focal lenght of 50mm.
