The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox 28mm F4.5 XF and the Fujifilm 23mm F1.4 R 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 23mm F1.4 R is the longer of the two lenses at 63mm.
