The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 23mm F1.4 C and the Canon RF 35mm F1.8 IS STM Macro 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 23mm F1.4 C is the longer of the two lenses at 79mm. The Canon RF 35mm F1.8 IS STM Macro with a length of 63mm, is 16mm shorter. On the other hand, the Canon RF 35mm F1.8 IS STM Macro has a larger diameter of 74mm compared to the Sigma 23mm F1.4 C's 66mm diameter.
Below you can find a scaled side-by-side image of Sigma 23mm F1.4 C and Canon RF 35mm F1.8 IS STM Macro to get a better idea of how their sizes compare in real life.
