The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 50mm f3.5 I 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. Voigtlander 50mm f3.5 I is the longer of the two lenses at 45mm. The Leica Summicron-M 50mm f2 with a length of 44mm, is 1mm shorter. On the other hand, the Leica Summicron-M 50mm f2 has a larger diameter of 53mm compared to the Voigtlander 50mm f3.5 I'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. Voigtlander 50mm f3.5 I weighs 150g, which means it is 90g (37%) 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 Voigtlander 50mm f3.5 I has a filter size of 34mm 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 34mm filters that we recommend you to consider for the Voigtlander 50mm f3.5 I:
And these are the 39mm filters that we recommend for the Leica Summicron-M 50mm f2:
Lens Mounts
Both the Voigtlander 50mm f3.5 I 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
Both lenses have the same focal range of
50mm but while Voigtlander 50mm f3.5 I has the fastest aperture of
F3.5, the Leica Summicron-M 50mm f2's widest aperture value is
F2.0.
