The type of photography that you are planning to use is an important decision factor. Here we have evaluated the SG-image 25mm F1.8 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. SG-image 25mm F1.8 is the longer of the two lenses at 32mm. The Canon EF-M 22mm f2 STM with a length of 24mm, is 8mm shorter. Besides being longer, the SG-image 25mm F1.8 also has a larger diameter of 67mm 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, 27% (40g) lighter than the SG-image 25mm F1.8's weight of 145g.
Filter Threads
The SG-image 25mm F1.8 has a filter size of 52mm 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 52mm filters that we recommend you to consider for the SG-image 25mm F1.8:
And these are the 43mm filters that we recommend for the Canon EF-M 22mm f2 STM:
Lens Mounts
The SG-image 25mm F1.8 has the Fujifilm X 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 Fujifilm X-T30 III, Fujifilm X-E5 and Fujifilm X-M5 for the Fujifilm X Mount and , and for the Canon EF-M Mount.
SG-image 25mm F1.8 is also available in the Sony E and Nikon Z mounts.
Focal Range
SG-image 25mm F1.8 is a prime lens with fixed focal lenght of 25mm which has an effective (full-frame 35mm equivalent) focal range of
37.5mm when used on a APS-C / DX format camera.
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.
