The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon RF 85mm F2 Macro IS STM and the Samyang MF 14mm F2.8 RF 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. Samyang MF 14mm F2.8 RF is the longer of the two lenses at 120mm. The Canon RF 85mm F2 Macro IS STM with a length of 91mm, is 29mm shorter. Besides being longer, the Samyang MF 14mm F2.8 RF also has a larger diameter of 87mm compared to the Canon RF 85mm F2 Macro IS STM's 78mm diameter.
