It seems that Canon is on fire with gear announcements today. In addition to the new EOS M6 Mark II and EOS 90D, the company has announced two out of three RF lenses we’ve been waiting for a while. The RF 15-35mm f/2.8 and RF 24-70 f/2.8 are now out, and they’re even a bit cheaper than we initially expected.
Canon RF 15-35mm f/2.8L IS USM
The Canon RF 15-35mm f/2.8L IS USM is a wide-angle zoom lens is designed for use with full-frame Canon RF-mount cameras. It features two UD (Ultra-Low Dispersion) elements, which help to minimize chromatic aberrations and color fringing. It also packs three aspherical elements which correct spherical aberrations and distortion. The lens features a rounded nine-blade diaphragm, which should contribute to a pleasing, smooth bokeh.
The lens features optical image stabilization which reduces camera shake by five stops. Canon also promises quick, accurate and smooth focusing thanks to the Nano USM system which utilizes both a ring-type USM and an STM mechanism.
Canon has applied Air-Sphere Coating (ASC) to lens elements in order to reduce backlit flaring and ghosting. There’s also a protective fluorine coating has on the front and rear element to resist fingerprints and smudges, or at least to make it easier to clean them. The lens is also weather-resistant, dust- and moisture-proof.
Here are the specs:
| Focal Length | 15 to 35mm |
| Maximum Aperture | f/2.8 |
| Lens Mount | Canon RF |
| Format Compatibility | Full-Frame |
| Maximum Magnification | 0.21x |

| Optical Design | 16 Elements in 12 Groups |
| Diaphragm Blades | 9, Rounded |
| Focus Type | Autofocus |
| Image Stabilization | Yes |
| Filter Size | 82 mm (Front) |
| Dimensions (ø x L) | 3.48 x 4.99″ / 88.5 x 126.8 mm |
| Weight | 1.85 lb / 840 g |
Canon RF 24-70 f/2.8 L IS USM
The 24-70mm lens offers a standard wide-angle to telephoto zoom range, and many photographers have one of these in their gear bags. And this one is designed for full-frame Canon RF-mount mirrorless cameras.
The lens packs three UD (Ultra-Low Dispersion) elements and three aspherical elements. These promised reduced chromatic aberrations and corrected spherical aberrations and distortion.
The rest of the specs are the same as those of the RF 15-35mm f/2.8L IS USM. The RF 24-70mm f/2.8 has a rounded nine-blade diaphragm for smooth bokeh. There’s an Air Sphere Coating (ASC) which reduces backlit flaring and ghosting. The lens also offers five-stop optical image stabilization and the Nano USM system with both a ring-type USM and an STM mechanism.
Protective fluorine coating makes smudge cleaning easier, and this lens is also dust- and moisture-proof.
Here are the specs:
| Focal Length | 24 to 70mm |
| Maximum Aperture | f/2.8 |
| Lens Mount | Canon RF |
| Format Compatibility | Full-Frame |
| Maximum Magnification | 0.3x |
| Minimum Focus Distance | 8.27″ / 21 cm |
| Optical Design | 21 Elements in 15 Groups |
| Diaphragm Blades | 9, Rounded |
| Focus Type | Autofocus |
| Image Stabilization | Yes |
| Filter Size | 82 mm (Front) |
| Dimensions (ø x L) | 3.48 x 4.95″ / 88.5 x 125.7 mm |
| Weight | 1.98 lb / 900 g |
Both RF 15-35mm f/2.8 and RF 24-70 f/2.8 are available for preorders and should start shipping in October. Despite the leaked price of $2,499, they’re a bit cheaper after all: they will set you back $2,299 each.
And what about the RF 70-200mm f/2.8L IS USM? It was always rumored along the 15-35mm and the 24-70mm as a part of the “holy trinity.” Well, considering that the latest reports claim it’s coming in December, I guess we’ll see the official announcement later this year, perhaps this fall.
