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 Summilux-M 21mm 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 Summilux-M 21mm f1.4 Asph is the longer of the two lenses at 66mm. The Leica APO-Summicron-M 35mm F2 ASPH with a length of 41mm, is 25mm shorter. Besides being longer, the Leica Summilux-M 21mm f1.4 Asph also has a larger diameter of 70mm compared to the Leica APO-Summicron-M 35mm F2 ASPH's 53mm 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 APO-Summicron-M 35mm F2 ASPH weighs 320g, which means it is 260g (44%) lighter than the Leica Summilux-M 21mm f1.4 Asph which has a weight of 580g.
