The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 12mm f1.4 and the 7artisans 12mm F2.8 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 12mm f1.4 is the longer of the two lenses at 70mm. The 7artisans 12mm F2.8 with a length of 66mm, is 4mm shorter. Besides being longer, the Sigma 12mm f1.4 also has a larger diameter of 68mm compared to the 7artisans 12mm F2.8's 63mm diameter.
