The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon 10-18mm f4.5-5.6 IS STM and the Canon EF-M 11-22mm f4-5.6 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 10-18mm f4.5-5.6 IS STM is the longer of the two lenses at 72mm. The Canon EF-M 11-22mm f4-5.6 with a length of 58mm, is 14mm shorter. Besides being longer, the Canon 10-18mm f4.5-5.6 IS STM also has a larger diameter of 75mm compared to the Canon EF-M 11-22mm f4-5.6'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 11-22mm f4-5.6 weighs 220g, 8% (20g) lighter than the Canon 10-18mm f4.5-5.6 IS STM's weight of 240g.
Filter Threads
The Canon 10-18mm f4.5-5.6 IS STM has a filter size of 67mm whereas the Canon EF-M 11-22mm f4-5.6 has a 55mm 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 Canon 10-18mm f4.5-5.6 IS STM:
And these are the 55mm filters that we recommend for the Canon EF-M 11-22mm f4-5.6:
