Magnification detail	0.09× at 100 mm, 0.24× at 200 mm, 0.34× at 300 mm and 0.41× at 400 mm; no unpublished AF/MF distinction inferred	0.17× at14mm and0.38× at30mm
Stabilisation detail
Stabilisation detail	Optical IS rated 5.5 stops at 400 mm on EOS R under CIPA, yaw/pitch; coordinated EOS R5 body/lens IS rated six stops under the same maker conditions. Cameralabs measured approximately five stops at 100 mm and three at 400 mm with EOS R6, a different test condition	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
Video features	Cameralabs found little focus breathing and mostly maintained focus while zooming in its tests; these are reviewer observations rather than maker parfocal certification	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
