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 1680 mm f/11 with 0.41× magnification; RF 2× gives 2400 mm f/16 with 0.60×; AF and IS operate with either extenderCanon RF extenders not compatible
Focus and stabilisation
AutofocusYesYes
Minimum focus distance4.3 m0.15 m (autofocus)
Maximum magnification0.29×0.35× (autofocus)

Autofocus detailRing-type USM; electronic full-time manual focus requires compatible body settings; original EOS R, RP and Ra are unsupported, and R5/R6 require firmware 1.3.0 or laterLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus
Focus distance detail4.3 m minimum focus; full range, 4.3–30 m and 30 m–infinity limiter settings; three manual-focus speeds and two stored focus presetsMaker specifies 0.15 m throughout the 7–14 mm range in autofocus
Magnification detail0.29× maximum magnification; approximately 241 × 161 mm subject fills a full-frame image at minimum focusMaximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image
Stabilisation detailFour-stop optical IS with EOS R, R5 or R3 under CIPA yaw/pitch conditions; modes 1, 2 and 3No lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditions
Video featuresAperture control in 1/8-stop increments; power-focus mode with two speeds selected by playback-ring rotationCircular 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
