The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Viltrox 75mm f1.2 AF 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. Viltrox 75mm f1.2 AF is the longer of the two lenses at 101mm. The Canon RF 85mm F2 Macro IS STM with a length of 91mm, is 10mm shorter. Besides being longer, the Viltrox 75mm f1.2 AF also has a larger diameter of 87mm 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, 25% (170g) lighter than the Viltrox 75mm f1.2 AF's weight of 670g.
Filter Threads
The Viltrox 75mm f1.2 AF has a filter size of 77mm 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 77mm filters that we recommend you to consider for the Viltrox 75mm f1.2 AF:
And these are the 67mm filters that we recommend for the Canon RF 85mm F2 Macro IS STM:
Lens Mounts
The Viltrox 75mm f1.2 AF has the Fujifilm X lens mount whereas the Canon RF 85mm F2 Macro IS STM has the Canon RF lens mount. Some of the latest released cameras that are compatible with these mounts are Fujifilm X-T30 III, Fujifilm X-E5 and Fujifilm X-M5 for the Fujifilm X Mount and Canon R6 V, Canon R6 III and Canon C50 for the Canon RF Mount.
Viltrox 75mm f1.2 AF is also available in the Sony E and Nikon Z mounts.

Viltrox 75mm f1.2 AF is a prime lens with fixed focal lenght of 75mm which has an effective (full-frame 35mm equivalent) focal range of
112.5mm when used on a APS-C / DX format camera.
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.
