The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon RF 16mm F2.8 STM and the Canon RF 50mm F1.8 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 50mm F1.8 STM is the longer of the two lenses at 41mm. The Canon RF 16mm F2.8 STM with a length of 40mm, is 1mm shorter. On the other hand, there is no difference between the max diameters of these lenses, both coming at 69mm.

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, 3% (5g) lighter than the Canon RF 16mm F2.8 STM's weight of 165g.
Filter Threads
Both the Canon RF 16mm F2.8 STM and the Canon RF 50mm F1.8 STM have the same Filter thread size of 43mm.
Below are links to the 43mm filters that we recommend you to consider for these lenses:
Lens Mounts
Both the Canon RF 16mm F2.8 STM and the Canon RF 50mm F1.8 STM has the same Canon RF lens mount. Some of the latest released cameras that are compatible with the Canon RF lenses are Canon R100, Canon R8 and Canon R50.
Focal Range
Canon RF 16mm F2.8 STM is a prime lens with fixed focal lenght of 16mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of
25.6mm.
On the other hand, the 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.
