The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox 35mm F1.7 Z and the Sigma 56mm F1.4 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 56mm F1.4 C is the longer of the two lenses at 60mm. The Viltrox 35mm F1.7 Z with a length of 56mm, is 4mm shorter. Besides being longer, the Sigma 56mm F1.4 C also has a larger diameter of 67mm compared to the Viltrox 35mm F1.7 Z's 64mm diameter.
