Aperture detailf/2.8–22 at 7 mm and f/3.5–29 at 14 mm; maker minimum-aperture figures use 1/3-stop displayMaker minimum aperture f/22 at14mm and f/38 at30mm using half-stop display; Ken Rockwell reports f/36 at30mm, while Digital Camera World lists f/32. Main values retain the maker’s explicitly stated display convention
DiaphragmNine aperture bladesSeven blades
Angle of viewHorizontal 190°–149°45′, vertical 190°–99°50′ and diagonal 190°–180° on full frame–
ProjectionCircular 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 frameAPS-C
CompatibilityCanon 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)Canon RF mount, APS-C image circle; UK maker lists compatible full-frame EOS R bodies with crop restrictions
Image circle detail–Physical14–30mm focal length;22.4–48mm equivalent angle of view on Canon APS-C, distinct from any additional movie crop

Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.15 m (autofocus)0.15 m
Maximum magnification0.35× (autofocus)0.38×
Optical stabilisationNoYes
Autofocus detailLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focusSTM autofocus; combined electronic focus/control ring. No dedicated AF/MF switch
Focus distance detailMaker specifies 0.15 m throughout the 7–14 mm range in autofocusMaker minimum focus0.15m throughout the zoom range; no AF/MF distinction published in the specification table
Magnification detailMaximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image0.17× at14mm and0.38× at30mm
Stabilisation detailNo lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditionsLens 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 featuresCircular 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 formatInternal 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
