Better figure, where one is clearly better
| CanonEF 16–35mm f/2.8L II USM | CanonRF 16–28mm F2.8 IS STM | |
|---|---|---|
| Overview | ||
| Released | 2007 | February 2025 |
| Optics | ||
| Lens type | Zoom | Zoom |
| Focal length | 16–35 mm | 16–28 mm |
| Maximum aperture | f/2.8 | f/2.8 |
| Minimum aperture | f/22 | f/22 |
| Optical construction | Sixteen elements in twelve groups | 16 elements in 13 groups |
| Special elements | Three aspherical elements of different types and two UD elements | Four UD elements and two aspherical elements, including a large-diameter replica aspherical element |
| Coatings | Super Spectra coating | – |
| Diaphragm | Seven circular blades | Nine blades |
| Angle of view | Horizontal 98°–54°; vertical 74°10′–38°; diagonal 108°10′–63° | Full-frame horizontal 98°–65°, vertical 74°10′–46° and diagonal 108°10′–75° |
| 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. Physical 16–28 mm focal length, distinct from RF16mm F2.8 STM prime |
| Teleconverter support | Canon EF1.4× II and EF2× II are incompatible; the manual also excludes 250D and 500D close-up lenses | – |
| Focus and stabilisation | ||
| Autofocus | Yes | Yes |
| Minimum focus distance | 0.28 m | 0.2 m |
| Maximum magnification | 0.22× | 0.26× |
| Optical stabilisation | No | Yes |
| Autofocus detail | Ring USM with mechanical full-time manual focusing; after One Shot AF, keep the shutter half-pressed while turning the focus ring | Lead-screw STM autofocus and electronic full-time manual focus; inner focusing keeps lens length constant during focusing |
| Focus distance detail | – | Maker minimum focus distance 0.20 m at 28 mm; Digital Camera World reports 0.25 m at 16 mm. Maker AF/MF distinction absent and omitted |
| Magnification detail | At 35 mm, EF12 II gives 0.62×–0.36× and EF25 II gives 1.11×–0.80×; both tubes are incompatible at 16 mm | Maker maximum magnification 0.26× at 28 mm; no unpublished AF/MF distinction inferred |
| Stabilisation detail | – | Lens optical IS rated 5.5 stops at 28 mm with EOS R8, yaw/pitch under CIPA2024. Coordinated EOS R1 body/lens IS rated eight central and7.5 peripheral stops at28mm, yaw/pitch/roll. Digital Camera World measured about four stops on EOS R8 at16mm, a different test condition |
| Video features | – | Maker describes smooth quiet movie autofocus; Digital Camera World reports minimal focus breathing |
| Design | ||
| Dust and moisture resistant | Yes | Yes |
| Filter diameter | 82 mm | 67 mm |
| Maximum diameter | 88.5 mm | 76.5 mm |
| Length | 111.6 mm | 91 mm |
| Weight | 640 g | 445 g (better) |
| Controls | Separate zoom and focus rings, AF/MF switch and distance window | Shared focus/control ring and AF/control/MF selector; separate zoom ring and IS switch |
| Zoom design | Constant exterior length with movement of the inner front tube according to both reviews | Retractable zoom must be extended for shooting; maker length91mm stored,112.8mm at16mm and102.1mm at28mm. Camera-side electronic distortion correction is part of the optical design according to Canon Camera Museum |
| Filter detail | 82 mm front thread; the manual permits one filter and specifies an 82 mm Canon circular polarising filter | 67 mm front filter thread |
| Weather resistance | The manual requires a separately sold Canon PROTECT filter for dust and water resistance because the front element moves during zooming; without it the lens is not dust or water resistant. Rubber mount seal | Dust and moisture resistant construction requires attachment to a camera; cannot completely prevent dust or water ingress and is not waterproof |
| Dimensions detail | Length measured from the mount to the front; caps add 21.5 mm with E-82U or 24 mm with E-82 II | Approximately76.5mm maximum diameter ×91mm stored;112.8mm long at16mm and102.1mm at28mm |
| Weight detail | UK specifications and Camera Museum publish 640 g; Canon's version 1.2 instruction manual publishes 635 g for the lens alone, without explaining the difference | Approximately445g lens |
| Lens hood | Reversible EW-88 hood | EW-73E, sold separately |
| In the box | Lens, hood and soft case according to Canon UK | UK maker store lists lens, E-67 II front cap, Lens Dust Cap RF and user manual |
| Release detail | Camera Museum's exact-model table records April 2007 marketing, whereas its III-generation history calls the II a March 2007 release; neither identifies a regional distinction, so the headline retains the year | February2025 marketed month in Canon Camera Museum; original Japan maker announcement and FAQ specify lateFebruary. No exact international first retail day inferred. Co-sold ultra-wide zooms are alternatives, with no inferred successor link |
