The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Fujifilm 23mm F2.8 and the Canon RF 28mm F2.8 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 28mm F2.8 STM is the longer of the two lenses at 25mm. The Fujifilm 23mm F2.8 with a length of 23mm, is 2mm shorter. Besides being longer, the Canon RF 28mm F2.8 STM also has a larger diameter of 69mm compared to the Fujifilm 23mm F2.8's 62mm diameter.
Below you can find a scaled side-by-side image of Fujifilm 23mm F2.8 and Canon RF 28mm F2.8 STM to get a better idea of how their sizes compare in real life.
Comparison image of the Fujifilm 23mm F2.8 and the Canon RF 28mm F2.8 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. Fujifilm 23mm F2.8 weighs 90g, which means it is 30g (25%) lighter than the Canon RF 28mm F2.8 STM which has a weight of 120g.
Filter Threads
The Fujifilm 23mm F2.8 has a filter size of 39mm whereas the Canon RF 28mm F2.8 STM 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 39mm filters that we recommend you to consider for the Fujifilm 23mm F2.8:
And these are the 55mm filters that we recommend for the Canon RF 28mm F2.8 STM:
Lens Mounts
The Fujifilm 23mm F2.8 has the Fujifilm X lens mount whereas the Canon RF 28mm F2.8 STM has the Canon RF 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 Canon R6 V , Canon R6 III and Canon C50 for the Canon RF Mount.
Focal Range
Fujifilm 23mm F2.8 is a prime lens with fixed focal lenght of 23mm which has an effective (full-frame 35mm equivalent) focal range of
34.5mm when used on a APS-C / DX format camera.
On the other hand, the Canon RF 28mm F2.8 STM is a prime lens with fixed focal lenght of 28mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of 44.8mm .
