| Focus distance detail | – | Autofocus minimum 0.20 m at 24 mm or 0.34 m at 105 mm; manual-focus Centre Focus Macro minimum 0.13 m at 24 mm, approximately 2.5 cm from the lens front, with sharpness concentrated in the image centre |
| Magnification detail | Maker maximum magnification 0.14× at 20 mm or 0.33× at 50 mm; no AF/MF mode specified in the table | Autofocus maximum 0.4× at 105 mm; manual-focus Centre Focus Macro maximum 0.5× at 24 mm, per Japan maker table and Camera Museum |
| Stabilisation detail | Maker six-stop optical IS or combined camera/lens eight stops at centre and corners under CIPA-2024, at maximum focal length with its specified camera; not guaranteed in every shooting setup | Optical IS rated five stops at 105 mm on EOS R under CIPA; lens optical rating is distinct from any camera sensor stabilisation |
| Video features | Internal multi-speed power zoom and optically suppressed focus breathing; zoom ring switches between powered and conventional manual operation | – |
