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 Sigma 85mm F1.4 EX DG HSM 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 Sigma 85mm F1.4 EX DG HSM with a length of 88mm, is 3mm shorter. On the other hand, the Sigma 85mm F1.4 EX DG HSM has a larger diameter of 86mm compared to the Canon RF 85mm F2 Macro IS STM's 78mm 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. Canon RF 85mm F2 Macro IS STM weighs 500g, which means it is 225g (31%) lighter than the Sigma 85mm F1.4 EX DG HSM which has a weight of 725g.
Filter Threads
The Canon RF 85mm F2 Macro IS STM has a filter size of 67mm whereas the Sigma 85mm F1.4 EX DG HSM has a 77mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
