The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica M 35mm f1.2 and the Leica Summilux-M 35mm 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 M 35mm f1.2 is the longer of the two lenses at 50mm. The Leica Summilux-M 35mm f1.4 ASPH with a length of 46mm, is 4mm shorter. Besides being longer, the Leica M 35mm f1.2 also has a larger diameter of 65mm compared to the Leica Summilux-M 35mm f1.4 ASPH's 56mm 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 Summilux-M 35mm f1.4 ASPH weighs 320g, 23% (96g) lighter than the Leica M 35mm f1.2's weight of 416g.

Filter Threads
The Leica M 35mm f1.2 has a filter size of 49mm whereas the Leica Summilux-M 35mm 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 49mm filters that we recommend you to consider for the Leica M 35mm f1.2:
And these are the 46mm filters that we recommend for the Leica Summilux-M 35mm f1.4 ASPH:
Lens Mounts
Both the Leica M 35mm f1.2 and the Leica Summilux-M 35mm 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
35mm but while Leica M 35mm f1.2 has the fastest aperture of
F1.2, the Leica Summilux-M 35mm f1.4 ASPH's widest aperture value is
F1.4.
