The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 20mm F3.5 SL II and the Sigma 24mm F1.4 DG HSM A 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 24mm F1.4 DG HSM A is the longer of the two lenses at 90mm. The Voigtlander 20mm F3.5 SL II with a length of 29mm, is 61mm shorter. Besides being longer, the Sigma 24mm F1.4 DG HSM A also has a larger diameter of 85mm compared to the Voigtlander 20mm F3.5 SL II's 63mm 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. Voigtlander 20mm F3.5 SL II weighs 205g, which means it is 460g (69%) lighter than the Sigma 24mm F1.4 DG HSM A which has a weight of 665g.
