| Mount and compatibility | ||
| Mounts | Canon RF | Canon RF |
| Image circle | Full frame | APS-C |
| Compatibility | Canon RF mount for full-frame and APS-C EOS R cameras | Canon RF mount, APS-C image circle; UK maker lists compatible full-frame EOS R bodies with crop restrictions |
| Image circle detail | – | Physical14–30mm focal length;22.4–48mm equivalent angle of view on Canon APS-C, distinct from any additional movie crop |
| Teleconverter support | Not compatible with Canon RF extenders | – |
| Focus and stabilisation | ||
| Autofocus | Yes | Yes |
| Minimum focus distance | 0.25 m | 0.15 m |
| Maximum magnification | 0.12× | 0.38× |
| Optical stabilisation | Yes | Yes |
| Autofocus detail | STM autofocus optimised for smooth, near-silent focusing in stills and video | STM autofocus; combined electronic focus/control ring. No dedicated AF/MF switch |
| Focus distance detail | Minimum focus 0.25 m | Maker minimum focus0.15m throughout the zoom range; no AF/MF distinction published in the specification table |
| Magnification detail | Maximum 0.12× at 20 mm and 0.06× at 10 mm | 0.17× at14mm and0.38× at30mm |
| Stabilisation detail | Up to five stops optical stabilisation tested with EOS R at 20 mm, or six stops coordinated stabilisation with EOS R3 at 20 mm; CIPA yaw and pitch testing. Peripheral Coordinated Control IS also compensates for peripheral blur | Lens optical IS rated five stops at30mm with EOS R10, yaw/pitch under CIPA2024. Coordinated EOS R7 body/lens IS rated7.5 central and5.5 peripheral stops at30mm, yaw/pitch/roll. Ken Rockwell measured about2.5–2.7 stops on EOS R50 V held at arm’s length, a different test condition |
| Video features | – | Internal power zoom controlled by lens ring, compatible camera controls or remote smartphone/Bluetooth control; UK maker describes two-step variable speed and15 adjustable levels. Movie Digital IS is camera processing with additional crop, distinct from lens optical IS |

| Weight detail | Approximately 570 g lens | Approximately181g lens, per maker; Ken Rockwell measured179.1g |
| Lens hood | Built-in lens hood | EW-63C, sold separately |
| In the box | Lens, RF dust cap, Lens Cap 10-20, LP1219 lens case and user manual | UK maker store lists lens, E-58 II front cap, Lens Dust Cap RF and user manual |
| Release detail | October 2023 marketed month in Canon Camera Museum | Canon USA scheduled the EOS R50 V kit containing this lens for April2025; Canon Indonesia’s22April2025 launch lists both kit and standalone lens for sale. Japan FAQ’s lateJuly2025 planned standalone release is a later regional date, not the earliest availability. No exact worldwide first-sale day inferred |
