Special elements
Special elements	Five UD and two replica aspherical elements	Gapless dual-layer diffractive optical element
Coatings
Coatings	Three ASC coatings and Super Spectra; fluorine coating on the front element	–
Aperture detail
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	Fixed f/11 aperture; cannot be stopped down
Diaphragm
Diaphragm	Nine aperture blades	No aperture blades
Angle of view
Angle of view	Horizontal 190°–149°45′, vertical 190°–99°50′ and diagonal 190°–180° on full frame	2°35′ horizontal, 1°40′ vertical and 3°05′ diagonal 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
Mounts
Mounts	Canon RF	Canon RF
Image circle
Image circle	Full frame	Full frame
Compatibility
Compatibility	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)	Canon RF mount for full-frame and APS-C EOS R cameras; EOS R, Ra and RP require compatible firmware
Teleconverter support
Teleconverter support	Canon RF extenders not compatible	RF 1.4× gives 1120 mm at f/16 and 0.19× maximum magnification; RF 2× gives 1600 mm at f/22 and 0.28×. Canon lists autofocus and stabilisation as supported with both; performance depends on camera and light levels
Focus and stabilisation
Autofocus
Autofocus	Yes	Yes
Minimum focus distance
Minimum focus distance	0.15 m (autofocus)	6 m
Maximum magnification
Maximum magnification	0.35× (autofocus)	0.14×
Optical stabilisation
Optical stabilisation	No	Yes
Autofocus detail
Autofocus detail	Leadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus	Lead-screw STM autofocus; Canon states approximately 40% horizontal × 60% vertical AF coverage in its original EOS R compatibility notes
Focus distance detail
Focus distance detail	Maker specifies 0.15 m throughout the 7–14 mm range in autofocus	Minimum focus 6 m; full-range or 20 m–infinity focus limiter (Cameralabs)
Magnification detail
Magnification detail	Maximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image	Maximum 0.14× without an extender
Stabilisation detail
Stabilisation detail	No lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditions	Up to four stops optical stabilisation under CIPA testing with EOS R
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	–

Zoom design
Zoom design	Internal zoom and focus retain the same physical lens length (Amateur Photographer; Digital Camera World)	Prime lens with a retracting storage barrel; extend and lock the barrel before shooting
Filter detail
Filter detail	No front screw-in filter thread; rear Drop-in Filter A system; supplied clear filter and optional Drop-in Variable ND Filter A or Drop-in Circular Polarizing Filter A	–
