Autofocus detailLead-screw STM with magnetic motor-speed sensor and feedback control, electronic manual focusSTM autofocus; combined electronic focus/control ring. No dedicated AF/MF switch
Focus distance detailMinimum focus at 28 mm is 0.27 m in AF or 0.24 m in MF; main figure retains the closer MF modeMaker minimum focus0.15m throughout the zoom range; no AF/MF distinction published in the specification table
Magnification detailMaximum 0.24× at 70 mm in either AF or MF0.17× at14mm and0.38× at30mm
Stabilisation detailLens optical IS rated 5.5 central stops at 70 mm with EOS R8, yaw/pitch under CIPA2024. Japan current feature page rates coordinated EOS R6 Mark II body/lens IS 7.5 central and 7.0 peripheral stops, yaw/pitch/roll; original press release gives the same coordinated rating with EOS R1Lens 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 featuresSmooth STM movie focusing; compatible camera breathing correction is digital. Cameralabs observes uncorrected focus breathing, more visible at 28 mmInternal 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
