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 Summilux-M 50mm f1.4 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 Summilux-M 50mm f1.4 ASPH is the longer of the two lenses at 53mm. The Voigtlander 50mm f3.5 I with a length of 45mm, is 8mm shorter. Besides being longer, the Leica Summilux-M 50mm f1.4 ASPH also has a larger diameter of 54mm 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 185g (55%) lighter than the Leica Summilux-M 50mm f1.4 ASPH which has a weight of 335g.
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 Summilux-M 50mm f1.4 ASPH has a 46mm 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 46mm filters that we recommend for the Leica Summilux-M 50mm f1.4 ASPH:
Lens Mounts
Both the Voigtlander 50mm f3.5 I and the Leica Summilux-M 50mm f1.4 ASPH 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 Summilux-M 50mm f1.4 ASPH's widest aperture value is
F1.4.
