Coatings
Coatings	–	Three ASC coatings and Super Spectra; fluorine coating on the front element
Aperture detail
Aperture detail	Minimum f/22 at 24 mm and f/40 at 105 mm	f/2.8–22 at 7 mm and f/3.5–29 at 14 mm; maker minimum-aperture figures use 1/3-stop display
Diaphragm
Diaphragm	Seven blades, circular aperture	Nine aperture blades
Angle of view
Angle of view	–	Horizontal 190°–149°45′, vertical 190°–99°50′ and diagonal 190°–180° on full frame
Projection
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

Image circle
Image circle	Full frame	Full frame
Compatibility
Compatibility	Canon RF mount, full-frame image circle; RF extenders and EF extension tubes not compatible	Canon 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
Teleconverter support	–	Canon RF extenders not compatible

Autofocus	Yes	Yes
Minimum focus distance
Minimum focus distance	0.13 m (manual focus)	0.15 m (autofocus)
Maximum magnification
Maximum magnification	0.5× (manual focus)	0.35× (autofocus)
Optical stabilisation
Optical stabilisation	Yes	No
Autofocus detail
Autofocus detail	Lead-screw STM, electronic manual focus; combined focus/control ring	Leadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus
Focus distance detail
Focus distance detail	Autofocus minimum 0.20 m at 24 mm or 0.34 m at 105 mm; manual-focus Centre Focus Macro minimum 0.13 m at 24 mm, approximately 2.5 cm from the lens front, with sharpness concentrated in the image centre	Maker specifies 0.15 m throughout the 7–14 mm range in autofocus
Magnification detail
Magnification detail	Autofocus maximum 0.4× at 105 mm; manual-focus Centre Focus Macro maximum 0.5× at 24 mm, per Japan maker table and Camera Museum	Maximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image
Stabilisation detail
Stabilisation detail	Optical IS rated five stops at 105 mm on EOS R under CIPA; lens optical rating is distinct from any camera sensor stabilisation	No lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditions
Video features
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
