The type of photography that you are planning to use is an important decision factor. Here we have evaluated the 7Artisans 135mm f1.8 L and the Leica SL 100mm F2.8 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 SL 100mm F2.8 is the longer of the two lenses at 137mm. The 7Artisans 135mm f1.8 L with a length of 136mm, is 1mm shorter. On the other hand, the 7Artisans 135mm f1.8 L has a larger diameter of 91mm compared to the Leica SL 100mm F2.8's 77mm diameter.
