The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summicron-M 50mm f2 and the Leica APO 50mm 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 APO 50mm f2 ASPH is the longer of the two lenses at 47mm. The Leica Summicron-M 50mm f2 with a length of 44mm, is 3mm 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 50mm f2 weighs 240g, which means it is 60g (19%) lighter than the Leica APO 50mm f2 ASPH which has a weight of 300g.
Below you can find the dimension and weight table of the Standard Prime Lenses in Leica M Mount for size comparison purposes.
