The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Thypoch 21mm f3.5 and the Leica APO-Summicron-M 35mm 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-Summicron-M 35mm F2 ASPH is the longer of the two lenses at 41mm. The Thypoch 21mm f3.5 with a length of 35mm, is 6mm shorter. On the other hand, the Thypoch 21mm f3.5 has a larger diameter of 58mm 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. Thypoch 21mm f3.5 weighs 131g, which means it is 189g (59%) lighter than the Leica APO-Summicron-M 35mm F2 ASPH which has a weight of 320g.
