Compatibility
Compatibility	Canon EOS R cameras; full-frame image circle. RF optical model distinct from EF24–70mm F2.8L generations and RF28–70mm F2.8 IS STM	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)

Minimum focus distance
Minimum focus distance	0.21 m	0.15 m (autofocus)
Maximum magnification
Maximum magnification	0.3×	0.35× (autofocus)
Optical stabilisation
Optical stabilisation	Yes	No
Autofocus detail
Autofocus detail	Nano USM autofocus; electronic full-time manual focus. Maker rear-focusing design does not change lens length while focusing	Leadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus
Focus distance detail
Focus distance detail	Maker minimum focus distance 0.21 m at 24 mm; Photography Blog reports 0.38 m at 70 mm. AF/MF mode distinction unpublished and omitted	Maker specifies 0.15 m throughout the 7–14 mm range in autofocus
Magnification detail
Magnification detail	Maker maximum magnification 0.30× at 32 mm; no unpublished AF/MF distinction inferred	Maximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image
Stabilisation detail
Stabilisation detail	Lens optical IS rated five stops under CIPA guidelines at 70 mm with EOS R; body stabilisation is separate	No lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditions
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
