The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 15mm f1.4 DG DN Art and the Sigma 20mm F2 DG DN C 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. Sigma 15mm f1.4 DG DN Art is the longer of the two lenses at 158mm. The Sigma 20mm F2 DG DN C with a length of 72mm, is 86mm shorter. Besides being longer, the Sigma 15mm f1.4 DG DN Art also has a larger diameter of 104mm compared to the Sigma 20mm F2 DG DN C's 70mm diameter.
Below you can find a scaled side-by-side image of Sigma 15mm f1.4 DG DN Art and Sigma 20mm F2 DG DN C to get a better idea of how their sizes compare in real life.
