Mount and compatibility
MountsCanon RFCanon RF
Image circleFull frameFull frame
CompatibilityCanon 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 EOS R cameras; full-frame image circle; stills iris-ring operation depends on camera support
Teleconverter supportCanon RF extenders not compatibleRF 1.4x gives 98–280 mm f/4 with 0.42× maximum magnification; RF 2x gives 140–400 mm f/5.6 with 0.6×; autofocus and stabilisation retained
Focus and stabilisation

Autofocus detailLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focusDual Nano USM motors independently drive two focusing groups for electronic floating focus control; full-time manual focus
Focus distance detailMaker specifies 0.15 m throughout the 7–14 mm range in autofocusClosest focus 0.49 m at 70 mm and 0.68 m at 200 mm; separate AF/MF distance modes not published
Magnification detailMaximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image0.2× at 70 mm and 0.3× at 200 mm (Canon Japan)
Stabilisation detailNo lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditionsLens OIS 5.5 stops at centre with EOS R8 at 200 mm; combined OIS/IBIS 7.5 centre and seven corner stops with EOS R1 at 200 mm under Canon's CIPA-2024 conditions
Video featuresCircular 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 formatOptically suppressed focus breathing and electronic floating focus control; optional PZ-E2/PZ-E2B adapters provide motorised zoom; iris operation in stills depends on camera and firmware
