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 APO 50mm 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 APO 50mm f2 ASPH is the longer of the two lenses at 47mm. The Voigtlander 50mm F1.5 with a length of 46mm, is 1mm shorter. On the other hand, the Voigtlander 50mm F1.5 has a larger diameter of 54mm compared to the Leica APO 50mm f2 ASPH's 53mm 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 F1.5 weighs 293g, which means it is 7g (2%) lighter than the Leica APO 50mm f2 ASPH which has a weight of 300g.
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 APO 50mm f2 ASPH 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 49mm filters that we recommend you to consider for the Voigtlander 50mm F1.5:
And these are the 39mm filters that we recommend for the Leica APO 50mm f2 ASPH:
Lens Mounts
Both the Voigtlander 50mm F1.5 and the Leica APO 50mm f2 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 APO 50mm f2 ASPH's widest aperture value is
F2.0.
