The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox 9mm F2.8 Z and the 7artisans 10mm f2.8 II 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. 7artisans 10mm f2.8 II Z is the longer of the two lenses at 95mm. The Viltrox 9mm F2.8 Z with a length of 56mm, is 39mm shorter. Besides being longer, the 7artisans 10mm f2.8 II Z also has a larger diameter of 75mm compared to the Viltrox 9mm F2.8 Z's 65mm diameter.
