Optical Design & Image Quality

The lens features a 7‑element, 6‑group construction, engineered to deliver high resolution across the frame. With a maximum aperture of f/1.4, it excels in low‑light situations and provides a shallow depth of field that isolates subjects with silky bokeh.

Its eight rounded diaphragm blades produce smooth, pleasing out‑of‑focus highlights—ideal for portraits where the background should gently fade into softness. The optical formula also minimizes chromatic aberration and distortion, ensuring crisp detail from edge to edge.

Fast & Quiet Autofocus

The lens employs Canon’s Micro USM (Ultra Sonic Motor), delivering rapid, near‑silent focusing that is especially useful in video work or quiet environments. The autofocus system locks quickly on subjects and maintains focus with minimal hunting.
