The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 56mm F1.4 C and the Voigtlander 58mm F1.4 SL II 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 Voigtlander 58mm F1.4 SL II with a length of 48mm, is 12mm shorter. Besides being longer, the Sigma 56mm F1.4 C also has a larger diameter of 67mm compared to the Voigtlander 58mm F1.4 SL II'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 56mm F1.4 C weighs 280g, which means it is 40g (12%) lighter than the Voigtlander 58mm F1.4 SL II which has a weight of 320g.
Filter Threads
The Sigma 56mm F1.4 C has a filter size of 55mm whereas the Voigtlander 58mm F1.4 SL II has a 58mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
