The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica M 35mm f1.2 and the Thypoch 21mm f3.5 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 M 35mm f1.2 is the longer of the two lenses at 50mm. The Thypoch 21mm f3.5 with a length of 35mm, is 15mm shorter. Besides being longer, the Leica M 35mm f1.2 also has a larger diameter of 65mm compared to the Thypoch 21mm f3.5's 58mm 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, 68% (285g) lighter than the Leica M 35mm f1.2's weight of 416g.
