Special elementsFive UD and two replica aspherical elementsOne UD element
CoatingsThree ASC coatings and Super Spectra; fluorine coating on the front element–
Aperture detailf/2.8–22 at 7 mm and f/3.5–29 at 14 mm; maker minimum-aperture figures use 1/3-stop display–
DiaphragmNine aperture bladesNine blades, circular aperture
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 frameFull frame
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, full-frame image circle
Teleconverter supportCanon RF extenders not compatible–
Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.15 m (autofocus)0.35 m
Maximum magnification0.35× (autofocus)0.5×
Optical stabilisationNoYes
Autofocus detailLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focusSTM autofocus, electronic manual focus and full-time manual focusing
Focus distance detailMaker specifies 0.15 m throughout the 7–14 mm range in autofocusMinimum focusing distance 0.35 m; three-position focus limiter; barrel extends towards close focus
Magnification detailMaximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye imageMaximum 0.5× reproduction, equivalent to half life-size
Stabilisation detailNo lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditionsHybrid optical IS corrects angular and shift shake; five-stop optical rating on EOS R under CIPA at 85 mm, or eight stops coordinated with EOS R5 sensor IS under CIPA at 85 mm
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 format–
