The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 50mm F1.5 and the Leica Summarit-M 50mm F2.4 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. Voigtlander 50mm F1.5 is the longer of the two lenses at 46mm. The Leica Summarit-M 50mm F2.4 ASPH with a length of 33mm, is 13mm shorter. Besides being longer, the Voigtlander 50mm F1.5 also has a larger diameter of 54mm compared to the Leica Summarit-M 50mm 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 50mm F2.4 ASPH weighs 105g, 64% (188g) lighter than the Voigtlander 50mm F1.5's weight of 293g.
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 F1.5 has a filter size of 49mm whereas the Leica Summarit-M 50mm F2.4 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 49mm filters that we recommend you to consider for the Voigtlander 50mm F1.5:
And these are the 46mm filters that we recommend for the Leica Summarit-M 50mm F2.4 ASPH:
Lens Mounts
Both the Voigtlander 50mm F1.5 and the Leica Summarit-M 50mm F2.4 ASPH has the same Leica M lens mount. Some of the latest released cameras that are compatible with the Leica M lenses are Leica M11 Monochrome, Leica M11 and Leica M10.
Focal Range
Both lenses have the same focal range of
50mm but while Voigtlander 50mm F1.5 has the fastest aperture of
F1.5, the Leica Summarit-M 50mm F2.4 ASPH's widest aperture value is
F2.4.
