The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 28mm f2.8 Type II and the Leica Summaron-M 28mm F5.6 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 28mm f2.8 Type II is the longer of the two lenses at 24mm. The Leica Summaron-M 28mm F5.6 with a length of 18mm, is 6mm shorter. On the other hand, there is no difference between the max diameters of these lenses, both coming at 51mm.
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 28mm f2.8 Type II weighs 106g, which means it is 59g (35%) lighter than the Leica Summaron-M 28mm F5.6 which has a weight of 165g.
Below you can find the dimension and weight table of the Wideangle Prime Lenses in Leica M Mount for size comparison purposes.

Filter Threads
The Voigtlander 28mm f2.8 Type II has a filter size of 39mm whereas the Leica Summaron-M 28mm F5.6 has a 34mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 39mm filters that we recommend you to consider for the Voigtlander 28mm f2.8 Type II:
And these are the 34mm filters that we recommend for the Leica Summaron-M 28mm F5.6:
Lens Mounts
Both the Voigtlander 28mm f2.8 Type II and the Leica Summaron-M 28mm F5.6 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
28mm but while Voigtlander 28mm f2.8 Type II has the fastest aperture of
F2.8, the Leica Summaron-M 28mm F5.6's widest aperture value is
F5.6.
