How it Works / Component Breakdown

The lens uses an STM (stepping motor) system to provide quiet and responsive autofocus suitable for both stills and video. Its optical construction of 11 elements in 9 groups is designed to balance sharpness and control aberrations, supported by specialised glass elements for improved image quality.

The 9-blade diaphragm shapes out-of-focus highlights for smoother background rendering, while the 52mm filter thread allows the use of ND, polarising, or creative filters. The close focusing distance enables tighter framing for detailed subjects.
