Each lens has its strengths, but the Canon's optical stabilization may be more beneficial for varied shooting conditions.

On the other hand, the VILTROX AF 9mm also employs a high-precision STM motor, ensuring fast and silent autofocus performance. This makes it suitable for both photography and videography, particularly in situations where noise can be disruptive.
