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 Voigtlander 35mm F1.2 Nokton 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. Voigtlander 35mm F1.2 Nokton is the longer of the two lenses at 78mm.
