The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 24mm F3.5 DG DN C and the Sigma 16mm F1.4 DC DN L 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 16mm F1.4 DC DN L is the longer of the two lenses at 92mm. The Sigma 24mm F3.5 DG DN C with a length of 49mm, is 43mm shorter. Besides being longer, the Sigma 16mm F1.4 DC DN L also has a larger diameter of 72mm compared to the Sigma 24mm F3.5 DG DN C's 64mm diameter.

The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Sigma 24mm F3.5 DG DN C weighs 225g, which means it is 180g (44%) lighter than the Sigma 16mm F1.4 DC DN L which has a weight of 405g.
