The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox 15mm F1.7 X and the Viltrox 13mm F1.4 Z 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. Viltrox 13mm F1.4 Z is the longer of the two lenses at 90mm. The Viltrox 15mm F1.7 X with a length of 56mm, is 34mm shorter. Besides being longer, the Viltrox 13mm F1.4 Z also has a larger diameter of 74mm compared to the Viltrox 15mm F1.7 X's 65mm 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 15mm F1.7 X weighs 180g, which means it is 275g (60%) lighter than the Viltrox 13mm F1.4 Z which has a weight of 455g.
