Angle of view12°–3°05′ diagonal, 10°–2°35′ horizontal and 7°–1°40′ verticalHorizontal 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 camerasCanon 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 supportRF 1.4× gives 280–1120 mm at f/9–13, maximum 0.37×; RF 2× gives 400–1600 mm at f/13–18, maximum 0.54×. Autofocus and stabilisation supported throughout the zoom range; autofocus coverage depends on camera and extenderCanon RF extenders not compatible
Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.8 m0.15 m (autofocus)
Maximum magnification0.25×0.35× (autofocus)
Optical stabilisationYesNo
Autofocus detailNano USM autofocus for fast stills focusing and smooth video transitionsLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus
Focus distance detailMinimum focus 0.8 m at 200 mm and 3.3 m at 800 mmMaker specifies 0.15 m throughout the 7–14 mm range in autofocus
Magnification detailMaximum 0.25× at 200 mm and 0.2× at 800 mmMaximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image
Stabilisation detailUp to 5.5 stops optical stabilisation with EOS R at 800 mm, or 5.5 stops coordinated stabilisation with EOS R3 at 800 mm; CIPA yaw and pitch testing. Coordinated correction has greater effect towards the wide endNo 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
