Industry-Leading 15-Blade Aperture: While most competitors use 9 or 11 blades, this lens features 15 rounded blades to produce exceptionally smooth, circular bokeh even when stopped down.

Superior Optical Construction: The lens utilizes 14 elements in 9 groups, including one Aspherical lens, two Extra-low Dispersion (ED) elements, and three High Refractive Index (HRI) elements to ensure high resolution and minimal aberration.

Hybrid Shooting Versatility: Equipped with a de-clickable aperture ring, users can switch between tactile clicks for photography and silent, stepless transitions for cinematic video recording.

Professional On-Lens Controls: Includes a customizable AFL (Autofocus Lock) button and a dedicated AF/MF switch, providing tactile control typically reserved for much more expensive lenses.

Robust Weather Sealing: Built with a durable aluminum alloy body and comprehensive dust and splash protection, plus a fluorine coating on the front element to repel water and oil.

Fast, Silent Autofocus: Powered by a precision STM (Stepping Motor), the lens fully supports modern camera features like Eye AF and real-time subject tracking for both stills and video.
