The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summicron-M 35mm f2 ASPH and the Leica Summicron-M 28mm 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 Summicron-M 28mm f2 ASPH is the longer of the two lenses at 41mm. The Leica Summicron-M 35mm f2 ASPH with a length of 35mm, is 6mm shorter. On the other hand, there is no difference between the max diameters of these lenses, both coming at 53mm.
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 Summicron-M 35mm f2 ASPH weighs 255g, which means it is 15g (5%) lighter than the Leica Summicron-M 28mm f2 ASPH which has a weight of 270g.
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 Leica Summicron-M 35mm f2 ASPH has a filter size of 39mm whereas the Leica Summicron-M 28mm f2 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 39mm filters that we recommend you to consider for the Leica Summicron-M 35mm f2 ASPH:
And these are the 46mm filters that we recommend for the Leica Summicron-M 28mm f2 ASPH:
Lens Mounts
Both the Leica Summicron-M 35mm f2 ASPH and the Leica Summicron-M 28mm 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 M EV1, Leica M11-D and Pixii Max.
Focal Range
Leica Summicron-M 35mm f2 ASPH is a prime lens with fixed focal lenght of 35mm.
On the other hand, the Leica Summicron-M 28mm f2 ASPH is a prime lens with fixed focal lenght of 28mm.
