The Canon RF45mm F1.2 STM is designed to be compact and reasonably priced, focusing on usability and versatility. It promises a refined look in the images straight from the camera, making it an appealing choice for portrait and lifestyle photography. The Fujifilm Fujinon XF23mmF2 R WR, on the other hand, boasts a stylish, lightweight design at just 180g and is weather and dust resistant, capable of functioning in temperatures as low as -10 degrees Celsius. Photographers who frequently shoot in challenging weather conditions may find the Fujifilm lens more appealing due to its robust construction.

Conversely, the Fujifilm Fujinon XF23mmF2 R WR excels in autofocus speed, capable of focusing in just 0.05 seconds when paired with compatible Fujifilm cameras. This rapid autofocus makes it an excellent choice for capturing spontaneous moments, especially in dynamic environments.
