Better figure, where one is clearly better
| CanonRF 7-14mm F2.8-3.5L FISHEYE STM | CanonRF 85mm F1.2 L USM | |
|---|---|---|
| Overview | ||
| Released | February 2026 | June 2019 |
| Optics | ||
| Lens type | Zoom | Prime |
| Focal length | 7–14 mm | 85 mm |
| Maximum aperture | f/2.8–3.5 | f/1.2 |
| Minimum aperture | f/22–29 | f/16 |
| Optical construction | 16 elements in 11 groups | Thirteen elements in nine groups |
| Special elements | Five UD and two replica aspherical elements | BR optics, UD and ground aspherical optics; ASC coating; front and rear fluorine coatings |
| Coatings | Three ASC coatings and Super Spectra; fluorine coating on the front element | – |
| Aperture detail | f/2.8–22 at 7 mm and f/3.5–29 at 14 mm; maker minimum-aperture figures use 1/3-stop display | – |
| Diaphragm | Nine aperture blades | Nine blades with circular aperture |
| Angle of view | Horizontal 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 | ||
| Mounts | Canon RF | Canon RF |
| Image circle | Full frame | Full frame |
| Compatibility | 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) | Canon RF mount for full-frame and APS-C EOS R cameras; extenders and EF12 II or EF25 II extension tubes not compatible |
| Teleconverter support | Canon RF extenders not compatible | – |
| Focus and stabilisation | ||
| Autofocus | Yes | Yes |
| Minimum focus distance | 0.15 m (autofocus) | 0.85 m |
| Maximum magnification | 0.35× (autofocus) | 0.12× |
| Optical stabilisation | No | No |
| Autofocus detail | Leadscrew-type STM focusing with position sensors; full-time manual focus; maker rear-focusing design maintains length during focus | Ring-type USM autofocus with electronic manual focusing and full-time manual override (Digital Camera World) |
| Focus distance detail | Maker specifies 0.15 m throughout the 7–14 mm range in autofocus | Minimum focus 0.85 m; internal focusing and focus limiter with 1.5 m to infinity setting (Digital Camera World) |
| Magnification detail | Maximum 0.35× at 14 mm in autofocus, measured at the image centre; do not assume identical magnification across a fisheye image | Maximum 0.12× |
| Stabilisation detail | No lens optical IS; maker separately lists compatible camera IBIS at seven stops at the centre/14 mm under CIPA-2024 conditions | No optical stabiliser |
| 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 | – |
| Design | ||
| Dust and moisture resistant | Yes | Yes |
| Filter diameter | – | 82 mm |
| Maximum diameter | 76.5 mm | 103.2 mm |
| Length | 109.4 mm | 117.3 mm |
| Weight | 476 g (better) | 1,195 g |
| Controls | Zoom, focus and customisable control rings; AF/MF switch, function button and zoom lock/limit control (Digital Camera World) | Electronic manual-focus and customisable lens control rings; AF/MF and focus limiter switches (Digital Camera World) |
| Zoom design | Internal zoom and focus retain the same physical lens length (Amateur Photographer; Digital Camera World) | – |
| Filter detail | No front screw-in filter thread; rear Drop-in Filter A system; supplied clear filter and optional Drop-in Variable ND Filter A or Drop-in Circular Polarizing Filter A | – |
| Weather resistance | Dust and moisture resistant with mount gasket; Canon states attachment to a camera is needed and protection does not prevent all dust or water ingress; no waterproof/IP claim | Weather-sealed construction with front and rear fluorine coatings |
| Dimensions detail | Approximately 76.5 mm maximum diameter × 109.4 mm length, excluding detachable hood | Approximately 103.2 mm maximum diameter × 117.3 mm length |
| Weight detail | Approximately 476 g lens | Approximately 1195 g lens |
| Lens hood | Detachable EW-76; remove for circular fisheye shooting to avoid the hood entering the image (Amateur Photographer; Digital Camera World) | ET-89 hood included |
| In the box | Drop-in clear filter included | Lens, E-82 II front cap, RF dust cap, ET-89 hood, LP1424 soft pouch and user manual |
| Release detail | Canon Japan specifies first sale on 20 February 2026; US announcement expected availability by the end of February, rather than the same exact regional day | June 2019 marketed month in Canon Camera Museum |
