| CanonRF 14mm F1.4L VCM | CanonRF 50mm F1.8 STM | |
|---|---|---|
| Overview | ||
| Released | February 2026 | December 2020 |
| Optics | ||
| Lens type | Prime | Prime |
| Focal length | 14 mm | 50 mm |
| Maximum aperture | f/1.4 | f/1.8 |
| Minimum aperture | f/16 | f/22 |
| Optical construction | 18 elements in 13 groups | Six elements in five groups |
| Special elements | One fluorite, one UD, one BR and three glass-moulded aspherical elements | One aspherical element |
| Coatings | Two ASC coatings, SWC and Super Spectra; fluorine coating on the front element | Super Spectra anti-reflection coating |
| Aperture detail | f/1.4–16; iris ring supports stepless aperture control in video, with stills compatibility dependent on camera model | – |
| Diaphragm | 11 circular aperture blades | Seven blades |
| Angle of view | 104° horizontal, 81° vertical and 114° diagonal on full frame | Full-frame horizontal40°, vertical27°30′ and diagonal46° |
| Projection | Rectilinear ultra-wide design | – |
| Mount and compatibility | ||
| Mounts | Canon RF | Canon RF |
| Image circle | Full frame | Full frame |
| Compatibility | Canon EOS R cameras; full-frame image circle; iris-ring functions depend on the camera and firmware | Canon EOS R cameras; full-frame RF mount. Distinct from EF50mmF1.8STM and RF50mmF1.2LUSM |
| Teleconverter support | Canon RF extenders not compatible | Canon RF extenders not compatible |
| Focus and stabilisation | ||
| Autofocus | Yes | Yes |
| Minimum focus distance | 0.24 m | 0.3 m |
| Maximum magnification | 0.11× | 0.25× |
| Optical stabilisation | No | No |
| Autofocus detail | Voice Coil Motor autofocus; electronic manual focus ring; maker rear-focus design maintains lens length during focusing | STM autofocus; electronic manual focus. Photography Blog reports selection of manual focus through the camera menu |
| Focus distance detail | – | Minimum focus distance0.30m; maker table does not distinguish AF and MF figures, so no mode inferred. Extending inner tube during close focusing, as documented by OpticalLimits |
| Magnification detail | – | Maker maximum magnification0.25×; no unpublished AF/MF distinction inferred |
| Stabilisation detail | No lens optical IS; maker lists camera IBIS CIPA-2024 performance of 6.5 stops at the centre and 2.5 at the corners, subject to the compatible camera/test conditions | No lens optical IS; compatible cameras may provide body stabilisation separately |
| Video features | Stepless iris ring; Canon Japan identifies EOS R1/EOS R5 Mark II stills iris-ring support; the US launch also names EOS R6 Mark III; do not assume the same support on every EOS R body | – |
| Design | ||
| Filter diameter | – | 43 mm |
| Dust and moisture resistant | Yes | – |
| Maximum diameter | 76.5 mm | 69.2 mm |
| Length | 112 mm | 40.5 mm |
| Weight | 578 g | 160 g (better) |
| Controls | Customisable control ring, electronic focus ring, iris ring with Auto-position lock, AF/MF switch and custom function button (controls confirmed by Digital Camera World) | Shared focus/control ring with focus-control selector; control mode can adjust camera settings |
| Filter detail | No front screw-in filter thread; rear gelatin-filter holder for 36.7 × 29.4 mm filters | 43mm front filter thread; maker lists Canon250D/500D close-up lenses and PL-C B circular polariser incompatible |
| Weather resistance | Dust and moisture resistant structure with mount gasket; Canon states resistance requires attachment to a camera and cannot prevent all dust or water ingress; no IP rating inferred | UK maker dust/moisture resistance entry is a dash; OpticalLimits explicitly reports no weather sealing |
| Dimensions detail | Approximately 76.5 mm maximum diameter × 112 mm length; integral hood | Approximately69.2mm maximum diameter ×40.5mm length, measured retracted by Canon |
| Weight detail | Approximately 578 g lens | Approximately160g lens |
| Lens hood | Built into the lens barrel; maker lists lens cap 14B, Lens Dust Cap RF and pouch LP1219 as accessories | ES-65B, sold separately |
| In the box | – | Lens, E-43 front cap and Lens Dust Cap RF; hood and LP1014 pouch are optional according to UK maker specifications |
| 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 | December2020 marketed month in Canon Camera Museum. Canon Canada scheduled mid-December2020 availability; Canon Japan records first sale24December2020. Headline retains month because the exact earliest international retail day is not documented; Japan's later day is not presented as a worldwide date |
