Performance: Sharpness, Autofocus, and Stabilization
Performance is where the Canon RF 100-500mm lens truly excels. Across the zoom range, image sharpness remains consistently high, especially in the center frame. Even at 500mm, detail retention is impressive when paired with modern high-resolution Canon RF cameras.
