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 support is body/firmware dependent
Teleconverter supportCanon RF extenders not compatibleCanon RF extenders not compatible
Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.15 m (autofocus)0.75 m
Maximum magnification0.35× (autofocus)0.12×

Autofocus detailLeadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focusVoice Coil Motor autofocus; electronic manual focus; maker notes movement/noise in unpowered internal VCM components is normal
Focus distance detailMaker specifies 0.15 m throughout the 7–14 mm range in autofocus–
Magnification detailMaximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image–
Stabilisation detailNo lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditionsNo lens optical IS; maker separately lists camera IBIS CIPA-2024 performance of eight stops at the centre and seven at the corners under its camera/test 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 stepless iris control; UK maker footnote excludes stills iris-ring operation on EOS R/RP/Ra/R3/R5/R6/R6 Mark II/R7/R8/R10/R50/R100/R5 C even with current firmware
