The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon RF 50mm F1.8 STM and the Canon RF 85mm F2 Macro IS STM 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 Canon RF 50mm F1.8 STM with a length of 41mm, is 50mm shorter. Besides being longer, the Canon RF 85mm F2 Macro IS STM also has a larger diameter of 78mm compared to the Canon RF 50mm F1.8 STM's 69mm diameter.
Below you can find a scaled side-by-side image of Canon RF 50mm F1.8 STM and Canon RF 85mm F2 Macro IS STM to get a better idea of how their sizes compare in real life.
Comparison image of the Canon RF 50mm F1.8 STM and the Canon RF 85mm F2 Macro IS STM Size and Weight 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 50mm F1.8 STM weighs 160g, which means it is 340g (68%) lighter than the Canon RF 85mm F2 Macro IS STM which has a weight of 500g.
Filter Threads
The Canon RF 50mm F1.8 STM has a filter size of 43mm whereas the Canon RF 85mm F2 Macro IS STM has a 67mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 43mm filters that we recommend you to consider for the Canon RF 50mm F1.8 STM:
And these are the 67mm filters that we recommend for the Canon RF 85mm F2 Macro IS STM:
Lens Mounts
Both the Canon RF 50mm F1.8 STM and the Canon RF 85mm F2 Macro IS STM has the same Canon RF lens mount . Some of the latest released cameras that are compatible with the Canon RF lenses are Canon R6 V , Canon R6 III and Canon C50 .
Focal Range
Canon RF 50mm F1.8 STM is a prime lens with fixed focal lenght of 50mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of
80mm .
On the other hand, the Canon RF 85mm F2 Macro IS STM is a prime lens with fixed focal lenght of 85mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of 136mm .
