CompatibilityCanon RF mount for full-frame and APS-C EOS R cameras; EOS R, Ra and RP require compatible firmwareCanon 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 supportRF 1.4× gives 1120 mm at f/16 and 0.19× maximum magnification; RF 2× gives 1600 mm at f/22 and 0.28×. Canon lists autofocus and stabilisation as supported with both; performance depends on camera and light levels–
Focus and stabilisation
AutofocusYesYes
Minimum focus distance6 m0.15 m
Maximum magnification0.14×0.38×
Optical stabilisationYesYes
Autofocus detailLead-screw STM autofocus; Canon states approximately 40% horizontal × 60% vertical AF coverage in its original EOS R compatibility notesSTM autofocus; combined electronic focus/control ring. No dedicated AF/MF switch
Focus distance detailMinimum focus 6 m; full-range or 20 m–infinity focus limiter (Cameralabs)Maker minimum focus0.15m throughout the zoom range; no AF/MF distinction published in the specification table
Magnification detailMaximum 0.14× without an extender0.17× at14mm and0.38× at30mm
Stabilisation detailUp to four stops optical stabilisation under CIPA testing with EOS RLens 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
