Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.9 m0.15 m
Maximum magnification0.33×0.38×
Optical stabilisationYesYes
Autofocus detailDual Nano USM autofocus with electronically controlled floating focus; full-time manual focus. Digital Camera World's initial EOS R action test preceded the firmware improvements it identifies, and its EOS R5 tracking test was substantially betterSTM autofocus; combined electronic focus/control ring. No dedicated AF/MF switch
Focus distance detailMaker minimum focus distance 0.9 m at 100 mm; Photography Blog reports 1.2 m at 500 mm. AF/MF mode distinction unpublished and omittedMaker minimum focus0.15m throughout the zoom range; no AF/MF distinction published in the specification table
Magnification detailMaker maximum magnification 0.33× at 500 mm; no unpublished AF/MF distinction inferred0.17× at14mm and0.38× at30mm
Stabilisation detailLens optical IS rated five stops with EOS R at 500 mm under CIPA; coordinated EOS R5 body and lens IS rated six stops with required firmware, separately from lens-only ratingLens 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
