The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summarit-M 35mm F2.4 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 Summarit-M 35mm F2.4 ASPH with a length of 34mm, is 7mm shorter. Besides being longer, the Leica Summicron-M 28mm 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, which means it is 73g (27%) lighter than the Leica Summicron-M 28mm f2 ASPH which has a weight of 270g.
Filter Threads
Both the Leica Summarit-M 35mm F2.4 ASPH and the Leica Summicron-M 28mm f2 ASPH have the same Filter thread size of 46mm.
Below are links to the 46mm filters that we recommend you to consider for these lenses:
