Aperture detailf/1.4–16; iris ring supports stepless aperture control in video, with stills compatibility dependent on camera modelf/2.8–22 at 7 mm and f/3.5–29 at 14 mm; maker minimum-aperture figures use 1/3-stop display
Diaphragm11 circular aperture bladesNine aperture blades
Angle of view104° horizontal, 81° vertical and 114° diagonal on full frameHorizontal 190°–149°45′, vertical 190°–99°50′ and diagonal 190°–180° on full frame
ProjectionRectilinear ultra-wide designCircular 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

Image circleFull frameFull frame
CompatibilityCanon EOS R cameras; full-frame image circle; iris-ring functions depend on the camera and firmwareCanon 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 supportCanon RF extenders not compatibleCanon RF extenders not compatible
Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.24 m0.15 m (autofocus)
Maximum magnification0.11×0.35× (autofocus)
Optical stabilisationNoNo
Autofocus detailVoice Coil Motor autofocus; electronic manual focus ring; maker rear-focus design maintains lens length during focusingLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus
Focus distance detail–Maker specifies 0.15 m throughout the 7–14 mm range in autofocus
Magnification detail–Maximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image
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 conditionsNo lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditions
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 bodyCircular 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
