Coatings–Three ASC coatings and Super Spectra; fluorine coating on the front element
Aperture detail–f/2.8–22 at 7 mm and f/3.5–29 at 14 mm; maker minimum-aperture figures use 1/3-stop display
DiaphragmNine bladesNine aperture blades
Angle of viewFull-frame horizontal 98°–65°, vertical 74°10′–46° and diagonal 108°10′–75°Horizontal 190°–149°45′, vertical 190°–99°50′ and diagonal 190°–180° on full frame
Projection–Circular 190° fisheye at 7 mm and frame-filling diagonal 180° fisheye at 14 mm on full frame; circular mode uses equidistant projection; neither is rectilinear
Mount and compatibility
MountsCanon RFCanon RF
Image circleFull frameFull frame
CompatibilityCanon EOS R cameras; full-frame image circle. Physical 16–28 mm focal length, distinct from RF16mm F2.8 STM primeCanon EOS R full-frame or APS-C cameras; APS-C cannot show the complete circular image and uses approximately 8.7 mm for diagonal coverage (Digital Camera World)
Teleconverter support–Canon RF extenders not compatible
Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.2 m0.15 m (autofocus)
Maximum magnification0.26×0.35× (autofocus)
Optical stabilisationYesNo
Autofocus detailLead-screw STM autofocus and electronic full-time manual focus; inner focusing keeps lens length constant during focusingLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus
Focus distance detailMaker minimum focus distance 0.20 m at 28 mm; Digital Camera World reports 0.25 m at 16 mm. Maker AF/MF distinction absent and omittedMaker specifies 0.15 m throughout the 7–14 mm range in autofocus
Magnification detailMaker maximum magnification 0.26× at 28 mm; no unpublished AF/MF distinction inferredMaximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image
Stabilisation detailLens optical IS rated 5.5 stops at 28 mm with EOS R8, yaw/pitch under CIPA2024. Coordinated EOS R1 body/lens IS rated eight central and7.5 peripheral stops at28mm, yaw/pitch/roll. Digital Camera World measured about four stops on EOS R8 at16mm, a different test conditionNo lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditions
Video featuresMaker describes smooth quiet movie autofocus; Digital Camera World reports minimal focus breathingCircular fisheye material can be converted to monoscopic 2D 180° VR with EOS VR Utility on supported cameras; not a stereoscopic dual-fisheye lens; conversion compatibility depends on body and recording format

Zoom designRetractable zoom must be extended for shooting; maker length91mm stored,112.8mm at16mm and102.1mm at28mm. Camera-side electronic distortion correction is part of the optical design according to Canon Camera MuseumInternal zoom and focus retain the same physical lens length (Amateur Photographer; Digital Camera World)
Filter detail67 mm front filter threadNo front screw-in filter thread; rear Drop-in Filter A system; supplied clear filter and optional Drop-in Variable ND Filter A or Drop-in Circular Polarizing Filter A
Weather resistanceDust and moisture resistant construction requires attachment to a camera; cannot completely prevent dust or water ingress and is not waterproofDust and moisture resistant with mount gasket; Canon states attachment to a camera is needed and protection does not prevent all dust or water ingress; no waterproof/IP claim

Release detailFebruary2025 marketed month in Canon Camera Museum; original Japan maker announcement and FAQ specify lateFebruary. No exact international first retail day inferred. Co-sold ultra-wide zooms are alternatives, with no inferred successor linkCanon Japan specifies first sale on 20 February 2026; US announcement expected availability by the end of February, rather than the same exact regional day
