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 Fujifilm XF 33mm F1.4 R LM WR 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. Fujifilm XF 33mm F1.4 R LM WR is the longer of the two lenses at 74mm. The Sigma 56mm F1.4 C with a length of 60mm, is 14mm shorter. On the other hand, there is no difference between the max diameters of these lenses, both coming at 67mm.
