The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 23mm F1.4 DC DN C and the Leica APO-SL 35mm F2 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 APO-SL 35mm F2 ASPH is the longer of the two lenses at 102mm. The Sigma 23mm F1.4 DC DN C with a length of 77mm, is 25mm shorter. Besides being longer, the Leica APO-SL 35mm F2 ASPH also has a larger diameter of 73mm compared to the Sigma 23mm F1.4 DC DN C's 66mm diameter.
