Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.24 m0.24 m (manual focus)
Maximum magnification0.11×0.24×
Optical stabilisationNoYes
Autofocus detailVoice Coil Motor autofocus; electronic manual focus ring; maker rear-focus design maintains lens length during focusingLead-screw STM with magnetic motor-speed sensor and feedback control, electronic manual focus
Focus distance detail–Minimum focus at 28 mm is 0.27 m in AF or 0.24 m in MF; main figure retains the closer MF mode
Magnification detail–Maximum 0.24× at 70 mm in either AF or MF
Stabilisation detailNo lens optical IS; maker lists camera IBIS CIPA-2024 performance of 6.5 stops at the centre and 2.5 at the corners, subject to the compatible camera/test conditionsLens 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 R1
Video featuresStepless iris ring; Canon Japan identifies EOS R1/EOS R5 Mark II stills iris-ring support; the US launch also names EOS R6 Mark III; do not assume the same support on every EOS R bodySmooth STM movie focusing; compatible camera breathing correction is digital. Cameralabs observes uncorrected focus breathing, more visible at 28 mm

ControlsCustomisable control ring, electronic focus ring, iris ring with Auto-position lock, AF/MF switch and custom function button (controls confirmed by Digital Camera World)Shared focus/control ring with AF/control/MF selector; separate zoom ring and stabilisation switch
Zoom design–Retractable barrel must be extended to 28 mm before shooting; length 92.2 mm stored, 112.4 mm at 28 mm and 138.9 mm at 70 mm, per Japan maker table
Filter detailNo front screw-in filter thread; rear gelatin-filter holder for 36.7 × 29.4 mm filters–
Weather resistanceDust and moisture resistant structure with mount gasket; Canon states resistance requires attachment to a camera and cannot prevent all dust or water ingress; no IP rating inferredUK maker states dust/moisture resistance, including rubber mount seal; no waterproof rating published

Weight detailApproximately 578 g lensUK current specification and store state 490 g; Japan current table, Camera Museum and original press release state 495 g. Main value follows UK specification; no undocumented regional variant inferred
Lens hoodBuilt into the lens barrel; maker lists lens cap 14B, Lens Dust Cap RF and pouch LP1219 as accessoriesEW-73D, sold separately
In the box–UK maker store lists lens, E-67 II front cap, rear dust cap and user manual
Release detailCanon Japan specifies first sale on 20 February 2026; US announcement expected availability by the end of February, rather than the same exact regional daySeptember 2024 marketed month in Canon Camera Museum; original maker release specifies 27 September in Japan. No exact worldwide first-sale day inferred; no successor link inferred across co-sold standard zooms
