The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Thypoch 75mm F1.4 M and the Leica Summilux-M 90mm F1.5 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 90mm F1.5 ASPH is the longer of the two lenses at 91mm. The Thypoch 75mm F1.4 M with a length of 78mm, is 13mm shorter. Besides being longer, the Leica Summilux-M 90mm F1.5 ASPH also has a larger diameter of 74mm compared to the Thypoch 75mm F1.4 M's 64mm diameter.
