The type of photography that you are planning to use is an important decision factor. Here we have evaluated the 7Artisans 24mm f1.8 and the Sigma 23mm F1.4 DC DN C 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 24mm f1.8 is the longer of the two lenses at 92mm. The Sigma 23mm F1.4 DC DN C with a length of 77mm, is 15mm shorter. Besides being longer, the 7Artisans 24mm f1.8 also has a larger diameter of 72mm compared to the Sigma 23mm F1.4 DC DN C's 66mm 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. Sigma 23mm F1.4 DC DN C weighs 340g, 19% (84g) lighter than the 7Artisans 24mm f1.8's weight of 424g.
