| Overview | ||
| Released | December 2014 | October 2018 |
| Optics | ||
| Lens type | Zoom | Zoom |
| Focal length | 24–105 mm | 24–105 mm |
| Maximum aperture | f/3.5–5.6 | f/4 |
| Minimum aperture | f/22–36 | f/22 |
| Optical construction | Seventeen elements in thirteen groups | 18 elements in 14 groups |
| Special elements | Aspherical and UD elements | 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 aperture f/22–36 with third-stop increments, or f/22–32 with half-stop increments, according to Canon's exact manual and Museum table | – |
| Diaphragm | Seven blades with a circular aperture | Nine blades with circular aperture |
| Angle of view | 84°–23°20′ diagonal, 74°–19°20′ horizontal and 53°–13° vertical | Full-frame horizontal 74°–19°20′, vertical 53°–13° and diagonal 84°–23°20′ |
| Mount and compatibility | ||
| Mounts | Canon EF | Canon RF |
| Image circle | Full frame | Full frame |
| Compatibility | Canon EF cameras with full-frame or APS-C sensors | Canon EOS R cameras; full-frame image circle. RF optical model distinct from EF24–105mmF4L generations and RF24–105mmF4–7.1STM |
| Teleconverter support | Canon's manual excludes extenders | Canon RF extenders not compatible; UK maker also lists EF12 II/EF25 II extension tubes incompatible |
| Adaptor support | EF12 II gives 0.61–0.50× at 24 mm and 0.46–0.12× at 105 mm; EF25 II is incompatible at 24 mm and gives 0.67–0.27× at 105 mm | – |
| Focus and stabilisation | ||
| Autofocus | Yes | Yes |
| Minimum focus distance | 0.4 m | 0.45 m |
| Maximum magnification | 0.3× | 0.24× |
| Optical stabilisation | Yes | Yes |
| Autofocus detail | Lead-screw STM autofocus with electronic manual focusing. One Shot AF permits manual adjustment with the shutter half-pressed; manual focusing is unavailable when the camera is off or the lens is asleep | Nano USM autofocus; electronic manual focus |
| Focus distance detail | Internal focusing with a non-rotating filter thread according to ePHOTOzine. Canon instructs users to finish zooming before focusing | Maker minimum focus distance 0.45 m; published AF/MF distinction absent and omitted |
| Magnification detail | – | Maker maximum magnification 0.24×; no unpublished AF/MF distinction inferred |
| Stabilisation detail | Four-stop claim measured at 105 mm with the EOS-1D X under CIPA standards. The manual describes automatic correction for still subjects and panning | 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 | Smooth Movie Servo AF with compatible cameras; the original manual lists EOS 70D, 700D, 100D and 650D, plus EOS M/M2 with an EF-EOS M adaptor | 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 | – | Yes |
| Filter diameter | 77 mm | 77 mm |
| Maximum diameter | 83.4 mm | 83.5 mm |
| Length | 104 mm | 107.3 mm |
| Weight | 525 g (better) | 700 g |
| Controls | AF/MF and stabilisation switches, separate focus and zoom rings, and a zoom lock at 24 mm | Zoom and focus rings, customisable lens control ring and zoom transport lock; OpticalLimits found no creeping during its test |
| Zoom design | Extending barrel with transport lock at the shortest position | Extending zoom barrel; maker physical dimensions measured retracted |
| Filter detail | – | 77 mm front filter thread |
| Weather resistance | – | Dust and moisture resistant construction, requiring attachment to a camera; cannot completely prevent dust/water ingress and is not waterproof |
| Dimensions detail | Maximum diameter × length; size and 525 g weight are lens-only. Caps add 24.2 mm to length according to Canon's manual | Approximately83.5mm maximum diameter ×107.3mm length in retracted state |
| Weight detail | – | Approximately700g lens |
| Lens hood | Optional EW-83M hood with release button; reversible for storage | 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 | Canon Camera Museum records December 2014 marketing; no first-sale day is given | 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 |
