The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox AF 56mm 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 AF 56mm f1.7 Z with a length of 56mm, is 4mm shorter. On the other hand, the Viltrox AF 56mm f1.7 Z has a larger diameter of 68mm compared to the Sigma 56mm F1.4 C's 67mm 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. Viltrox AF 56mm f1.7 Z weighs 187g, which means it is 93g (33%) lighter than the Sigma 56mm F1.4 C which has a weight of 280g.

The Viltrox AF 56mm f1.7 Z has a filter size of 52mm whereas the Sigma 56mm F1.4 C has a 55mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
