The type of photography that you are planning to use is an important decision factor. Here we have evaluated the 7artisans 50mm F1.1 and the Leica Noctilux-M 75mm F1.25 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 Noctilux-M 75mm F1.25 ASPH is the longer of the two lenses at 91mm. The 7artisans 50mm F1.1 with a length of 49mm, is 42mm shorter. Besides being longer, the Leica Noctilux-M 75mm F1.25 ASPH also has a larger diameter of 74mm compared to the 7artisans 50mm F1.1's 60mm diameter.
