The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 35mm F2 DG DN and the Voigtlander Nokton 17.5mm F0.95 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. Voigtlander Nokton 17.5mm F0.95 ASPH is the longer of the two lenses at 80mm. The Sigma 35mm F2 DG DN with a length of 65mm, is 15mm shorter. On the other hand, the Sigma 35mm F2 DG DN has a larger diameter of 70mm compared to the Voigtlander Nokton 17.5mm F0.95 ASPH'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. Sigma 35mm F2 DG DN weighs 325g, which means it is 215g (39%) lighter than the Voigtlander Nokton 17.5mm F0.95 ASPH which has a weight of 540g.
