Optical constructionSixteen elements in twelve groups16 elements in 11 groups
Special elementsThree glass-moulded aspherical elements and UD elements; SWC and ASC coatings; fluorine coatings on the front and rear elementsFive UD and two replica aspherical elements
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 blades with circular apertureNine aperture blades
Angle of view–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 RF mount for full-frame and APS-C EOS R cameras; RF extenders not compatibleCanon 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

Autofocus detailNano USM motor; electronic manual focusingLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus
Focus distance detailMinimum focus 0.28 mMaker specifies 0.15 m throughout the 7–14 mm range in autofocus
Magnification detailMaximum 0.21× at 35 mmMaximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image
Stabilisation detailOptical IS rated five stops with EOS R at 35 mm under CIPA standardsNo lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditions
Video features–Circular 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
