Better figure, where one is clearly better
| CanonEF 24–105mm f/4L IS II USM | CanonRF 28–70mm F2.8 IS STM | |
|---|---|---|
| Overview | ||
| Released | 2016 | September 2024 |
| Optics | ||
| Lens type | Zoom | Zoom |
| Focal length | 24–105 mm | 28–70 mm |
| Maximum aperture | f/4 | f/2.8 |
| Minimum aperture | f/22 | f/22 |
| Optical construction | Seventeen elements in twelve groups | 15 elements in 12 groups |
| Special elements | Four aspherical elements | Two UD elements and two GMo aspherical elements |
| Coatings | Air Sphere Coating; front and rear fluorine coating according to The Digital Picture | Super Spectra; no fluorine coating, per UK maker specification |
| Diaphragm | Ten blades with a circular aperture | Nine blades |
| Angle of view | 84°–23°20′ diagonal, 74°–19°20′ horizontal and 53°–13° vertical | – |
| Mount and compatibility | ||
| Mounts | Canon EF | Canon RF |
| Image circle | Full frame | Full frame |
| Compatibility | Canon EF full-frame and APS-C DSLRs; EOS M cameras require an EF-EOS M mount adaptor | Full-frame image circle, Canon RF mount; incompatible with EF DSLRs and EOS M bodies. Canon RF extenders not compatible |
| Teleconverter support | Canon's manual excludes extenders | – |
| Adaptor support | EF12 II gives 0.60–0.50× at 24 mm and 0.41–0.12× at 105 mm; EF25 II is incompatible at 24 mm and gives 0.61–0.27× at 105 mm | – |
| Focus and stabilisation | ||
| Autofocus | Yes | Yes |
| Minimum focus distance | 0.45 m | 0.24 m (manual focus) |
| Maximum magnification | 0.24× | 0.24× |
| Optical stabilisation | Yes | Yes |
| Autofocus detail | USM autofocus with full-time manual focusing. Canon's manual specifies turning the ring with the shutter half-pressed after One Shot AF | Lead-screw STM with magnetic motor-speed sensor and feedback control, electronic manual focus |
| Focus distance detail | Internal focusing according to The Digital Picture; Canon instructs users to finish zooming before focusing | Minimum focus at 28 mm is 0.27 m in AF or 0.24 m in MF; main figure retains the closer MF mode |
| Magnification detail | – | Maximum 0.24× at 70 mm in either AF or MF |
| Stabilisation detail | Canon claims four-stop optical stabilisation. The exact manual describes automatic adjustment for still subjects and panning, with correction perpendicular to the panning direction | Lens optical IS rated 5.5 central stops at 70 mm with EOS R8, yaw/pitch under CIPA2024. Japan current feature page rates coordinated EOS R6 Mark II body/lens IS 7.5 central and 7.0 peripheral stops, yaw/pitch/roll; original press release gives the same coordinated rating with EOS R1 |
| Video features | – | Smooth STM movie focusing; compatible camera breathing correction is digital. Cameralabs observes uncorrected focus breathing, more visible at 28 mm |
| Design | ||
| Dust and moisture resistant | Yes | Yes |
| Filter diameter | 77 mm | 67 mm |
| Maximum diameter | 83.5 mm | 76.5 mm |
| Length | 118 mm | 92.2 mm |
| Weight | 795 g | 490 g (better) |
| Controls | AF/MF and stabilisation switches, separate focus and zoom rings, distance window, infrared index and transport lock at 24 mm | Shared focus/control ring with AF/control/MF selector; separate zoom ring and stabilisation switch |
| Zoom design | Extending barrel; zoom lock holds the shortest 24 mm position | Retractable barrel must be extended to 28 mm before shooting; length 92.2 mm stored, 112.4 mm at 28 mm and 138.9 mm at 70 mm, per Japan maker table |
| Weather resistance | Canon UK describes dust and moisture sealing; the manual identifies a rubber mount ring. The Digital Picture recommends a protective filter to complete front sealing | UK maker states dust/moisture resistance, including rubber mount seal; no waterproof rating published |
| Dimensions detail | Maximum diameter × retracted length; size and 795 g weight are lens-only. Caps add 24.2 mm to length according to Canon's manual | Maximum diameter 76.5 mm; 92.2 mm length when retracted |
| Weight detail | – | UK current specification and store state 490 g; Japan current table, Camera Museum and original press release state 495 g. Main value follows UK specification; no undocumented regional variant inferred |
| Lens hood | EW-83M hood with release button; reversible for storage | EW-73D, sold separately |
| In the box | Lens, E-77 II front cap, Dust Lens Cap E, EW-83M hood, LP1219 case and manual according to Canon UK | UK maker store lists lens, E-67 II front cap, rear dust cap and user manual |
| Release detail | Canon Camera Museum's exact-model table records October 2016 marketing; its later RF 24–105mm page retrospectively says November 2016. The year is used because the maker gives conflicting months without explaining a regional difference | September 2024 marketed month in Canon Camera Museum; original maker release specifies 27 September in Japan. No exact worldwide first-sale day inferred; no successor link inferred across co-sold standard zooms |
