The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica APO-Summicron-M 35mm F2 ASPH and the Leica Summarit-M 35mm 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. Leica APO-Summicron-M 35mm F2 ASPH is the longer of the two lenses at 41mm. The Leica Summarit-M 35mm F2.4 ASPH with a length of 34mm, is 7mm shorter. Besides being longer, the Leica APO-Summicron-M 35mm F2 ASPH also has a larger diameter of 53mm compared to the Leica Summarit-M 35mm 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 35mm F2.4 ASPH weighs 197g, 38% (123g) lighter than the Leica APO-Summicron-M 35mm F2 ASPH's weight of 320g.
Filter Threads
The Leica APO-Summicron-M 35mm F2 ASPH has a filter size of 39mm whereas the Leica Summarit-M 35mm 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 39mm filters that we recommend you to consider for the Leica APO-Summicron-M 35mm F2 ASPH:
And these are the 46mm filters that we recommend for the Leica Summarit-M 35mm F2.4 ASPH:
Lens Mounts
Both the Leica APO-Summicron-M 35mm F2 ASPH and the Leica Summarit-M 35mm 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
35mm but while Leica APO-Summicron-M 35mm F2 ASPH has the fastest aperture of
F2, the Leica Summarit-M 35mm F2.4 ASPH's widest aperture value is
F2.4.
