Autofocus Performance
Both the Canon RF 50mm F1.8 STM and the RF16mm F2.8 STM lenses feature advanced autofocus systems designed for smooth and fast focusing. The RF 50mm F1.8 employs a stepping motor (STM) that ensures near-silent operation, making it a great option for video work as well as still photography. This lens is particularly effective in situations where quick focus is necessary, such as during events or fast-paced shoots.
The RF16mm F2.8 also utilizes a gear-type STM motor, providing a similar level of smoothness and quietness during autofocus. This lens is especially well-suited for vlogging and video recording, where noise can be distracting. Both lenses will serve well in different contexts, but the choice between them may hinge on whether you value the faster and quieter performance of the RF 50mm in portrait settings or the RF16mm’s advantages for video.
