The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Samyang 12mm f2.0 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. Samyang 12mm f2.0 is the longer of the two lenses at 59mm. The Canon EF-M 22mm f2 STM with a length of 24mm, is 35mm shorter. Besides being longer, the Samyang 12mm f2.0 also has a larger diameter of 73mm compared to the Canon EF-M 22mm f2 STM's 61mm 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 EF-M 22mm f2 STM weighs 105g, 59% (155g) lighter than the Samyang 12mm f2.0's weight of 260g.
Filter Threads
The Samyang 12mm f2.0 has a filter size of 67mm 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 67mm filters that we recommend you to consider for the Samyang 12mm f2.0:
