| Overview | ||
| Released | April 2020 | October 2018 |
| Optics | ||
| Lens type | Zoom | Zoom |
| Focal length | 24–105 mm | 24–105 mm |
| Maximum aperture | f/4–7.1 | f/4 |
| Minimum aperture | f/22–40 | f/22 |
| Optical construction | 13 elements in 11 groups, per Japan maker specification and Canon Camera Museum | 18 elements in 14 groups |
| Special elements | Aspherical element shown in Canon Camera Museum optical diagram | Three glass-moulded aspherical elements and one UD element |
| Coatings | – | ASC and Super Spectra anti-reflection coatings; fluorine coatings on front and rearmost surfaces |
| Aperture detail | Minimum f/22 at 24 mm and f/40 at 105 mm | – |
| Diaphragm | Seven blades, circular aperture | Nine blades with circular aperture |
| Angle of view | – | Full-frame horizontal 74°–19°20′, vertical 53°–13° and diagonal 84°–23°20′ |
| Mount and compatibility | ||
| Mounts | Canon RF | Canon RF |
| Image circle | Full frame | Full frame |
| Compatibility | Canon RF mount, full-frame image circle; RF extenders and EF extension tubes not compatible | Canon EOS R cameras; full-frame image circle. RF optical model distinct from EF24–105mmF4L generations and RF24–105mmF4–7.1STM |
| Teleconverter support | – | Canon RF extenders not compatible; UK maker also lists EF12 II/EF25 II extension tubes incompatible |
| Focus and stabilisation | ||
| Autofocus | Yes | Yes |
| Minimum focus distance | 0.13 m (manual focus) | 0.45 m |
| Maximum magnification | 0.5× (manual focus) | 0.24× |
| Optical stabilisation | Yes | Yes |
| Autofocus detail | Lead-screw STM, electronic manual focus; combined focus/control ring | Nano USM autofocus; electronic manual focus |
| Focus distance detail | Autofocus minimum 0.20 m at 24 mm or 0.34 m at 105 mm; manual-focus Centre Focus Macro minimum 0.13 m at 24 mm, approximately 2.5 cm from the lens front, with sharpness concentrated in the image centre | Maker minimum focus distance 0.45 m; published AF/MF distinction absent and omitted |
| Magnification detail | Autofocus maximum 0.4× at 105 mm; manual-focus Centre Focus Macro maximum 0.5× at 24 mm, per Japan maker table and Camera Museum | Maker maximum magnification 0.24×; no unpublished AF/MF distinction inferred |
| Stabilisation detail | Optical IS rated five stops at 105 mm on EOS R under CIPA; lens optical rating is distinct from any camera sensor stabilisation | Lens optical IS rated five stops, CIPA with EOS R at105mm in Canon Camera Museum; OpticalLimits obtained about3.5–4stops in its electronic-shutter test, a separate measured result |
| Video features | – | Nano USM supports smooth movie autofocus; maker describes combined lens optical and camera electronic video IS separately from lens-only rating |
| Design | ||
| Dust and moisture resistant | No | Yes |
| Filter diameter | 67 mm | 77 mm |
| Maximum diameter | 76.6 mm | 83.5 mm |
| Length | 88.8 mm | 107.3 mm |
| Weight | 395 g (better) | 700 g |
| Controls | Combined focus/control ring, zoom ring and separate stabilisation switch; OpticalLimits notes manual/auto focus is selected through camera settings rather than an AF/MF lens switch | Zoom and focus rings, customisable lens control ring and zoom transport lock; OpticalLimits found no creeping during its test |
| Zoom design | Extending zoom barrel | Extending zoom barrel; maker physical dimensions measured retracted |
| Filter detail | – | 77 mm front filter thread |
| Weather resistance | OpticalLimits and Cameralabs report no weather sealing | Dust and moisture resistant construction, requiring attachment to a camera; cannot completely prevent dust/water ingress and is not waterproof |
| Dimensions detail | Approximately 76.6 mm maximum diameter ×88.8 mm length | Approximately83.5mm maximum diameter ×107.3mm length in retracted state |
| Weight detail | Approximately 395 g lens | Approximately700g lens |
| Lens hood | EW-73D, not bundled | EW-83N |
| In the box | – | UK maker store lists lens, E-77 II cap, Lens Dust Cap RF, EW-83N hood, LP1319 case and user manual |
| Release detail | April 2020 marketed month in Canon Camera Museum | Canon Japan FAQ gives first sale 25 October 2018, consistent with Camera Museum marketed month; no exact UK on-sale day inferred. Maker Japan offers a control-ring de-click service, so the launch DCW statement that it cannot be de-clicked is not treated as current service availability. Co-sold RF standard zooms are alternatives, not inferred successor links |
