The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon EF 50mm f/1.8 STM and the Canon EF-M 22mm f2 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 EF 50mm f/1.8 STM is the longer of the two lenses at 39mm. The Canon EF-M 22mm f2 STM with a length of 24mm, is 15mm shorter. Besides being longer, the Canon EF 50mm f/1.8 STM also has a larger diameter of 69mm compared to the Canon EF-M 22mm f2 STM's 61mm diameter.
Below you can find a scaled side-by-side image of Canon EF 50mm f/1.8 STM and Canon EF-M 22mm f2 STM to get a better idea of how their sizes compare in real life.
Comparison image of the Canon EF 50mm f/1.8 STM and the Canon EF-M 22mm f2 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 EF-M 22mm f2 STM weighs 105g, 33% (54g) lighter than the Canon EF 50mm f/1.8 STM's weight of 159g.
Filter Threads
The Canon EF 50mm f/1.8 STM has a filter size of 49mm whereas the Canon EF-M 22mm f2 STM has a 43mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 49mm filters that we recommend you to consider for the Canon EF 50mm f/1.8 STM:
And these are the 43mm filters that we recommend for the Canon EF-M 22mm f2 STM:
Lens Mounts
The Canon EF 50mm f/1.8 STM has the Canon EF lens mount whereas the Canon EF-M 22mm f2 STM has the Canon EF-M lens mount . Some of the latest released cameras that are compatible with these mounts are Blackmagic URSA 12K LF , Z CAM E2-F6 II 6K and Z CAM E2-S6 II 6K for the Canon EF Mount and
Focal Range
Canon EF 50mm f/1.8 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 EF-M 22mm f2 STM is a prime lens with fixed focal lenght of 22mm which has an effective (full-frame 35mm equivalent) focal range of 33mm when used on a APS-C / DX format camera.
