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 85mm F1.4 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. Canon RF 85mm F2 Macro IS STM is the longer of the two lenses at 91mm. The Samyang 85mm F1.4 with a length of 75mm, is 16mm shorter. On the other hand, there is no difference between the max diameters of these lenses, both coming at 78mm.
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. Canon RF 85mm F2 Macro IS STM weighs 500g, which means it is 39g (7%) lighter than the Samyang 85mm F1.4 which has a weight of 539g.
