Choosing the best Canon RF lenses for your EOS R system camera is easier than it once was. Now four years into the development of Canon’s mirrorless EOS R system, there are now plenty of optics to choose from. The Canon RF range began as a handful of primes in 2018 and has grown into a diverse system of more than 26 optics that offers everything from wide-angle zooms to standard zooms to super telephoto lenses. There’s even now a dual fisheye lens for shooting 180 VR content!
Before we round up our picks for the best Canon RF lenses, though, let’s take a look at the Canon RF mount design and what makes it so innovative.
RF mount dimensions
The Canon RF is the same 54mm diameter as the old EF mount, which supports ultra-wide apertures. However, Canon has dramatically reduced the flange back distance from 44mm to 20mm. What this means is that the back of the lens now sits much closer to the image sensor on RF mount bodies. This design cuts down on bending light rays that previously would pass through the lens and create aberrations and other distortions.
What’s more, the reduced flange distance means Canon can design its RF lenses and R system camera bodies much smaller and, thus, lighter.
Can I use a Canon EF lens on an RF mount body?
You can use Canon EF lenses on an RF mount body only with an adapter. Though Canon EF and RF lenses have the same 54mm diameter, they cannot be used interchangeably. Both lens mounts have a three-tab bayonet design, but they bayonets are placed in different positions.
To use your EF lenses on an R system camera, you’ll need the Canon Mount Adapter EF-EOS R. This adapter also lets you many any EF-S lenses you may have. You can also use Canon’s Control Ring Mount Adapter EF-EOS R, which is effectively the same but adds a Lens Control Ring that you can customise to control different exposure settings.
12-pin connection
The other innovation of the RF mount design are its 12 points for data transfer around mount. Canon EF mount bodies had eight pins, so the RF mount offers a 50% increase. This means RF lenses and R system bodies can work in tandem to share higher volumes of data at faster rates.
What are the actual benefits of this faster data transfer? As a photographer you’ll realise these benefits in better AF performance, image stabilisation and better, faster overall performance.
In-lens Image Stabilisation
Some Canon RF lenses come equipped with in-lens Image Stabilisation. These lenses have a built-in dual gyro sensor that can detect motion blur from your movements. This dual gyro sensor system then sends a message to the camera’s processor, and the camera accounts for the movement. While many other lenses out there have similar in-lens stabilisation systems, what makes the RF lenses’ system unique are its dual sensors, which are designed to ascertain more nuanced movements.
The best Canon RF lenses you can buy today
As we mentioned above, there are now 26 Canon RF lenses you can choose from at the time of writing. We won’t list them all here. Instead, we’ve focused on the best Canon RF lenses to start your collection, choosing optics to cover all the most common focal lengths.
Canon RF 28-70mm F2L USM
Specification
- Product type: Standard zoom lens
- Announced: 5th September 2018
- Mount: Canon RF
- Format: Full-frame
- Focal length: 28-70mm
- Maximum aperture: f/2.0
- Minimum aperture: f/22
- Construction: 19 elements in 13 groups
- Coatings: ASC (Air Sphere Coating), Super Spectra and fluorine
- Focusing system: USM
- Minimum focus distance: 39cm from the focal plane
- Maximum reproduction ratio: 0.18x
- Stabilisation: No
- Number of diaphragm blades: 9
- Filter size: 95mm
- Weight: 1430g
- Diameter x length: 103.8 x 139.8
The Canon RF 288-70mm f2L USM is an unusual lens. It’s a full-frame zoom lens covering a popular focal length range (although 24-70mm is more common), with a larger than average constant aperture of f/2.0. This large aperture is useful in low light conditions and when the background needs a bit of extra blur, but it also makes the lens very big and heavy.
In fact, at 1430g, the RF 28-70mm f/2L USM is 360g heavier than the RF 70-200mm F2.8L IS. As a result, it’s cumbersome to use it routinely and it seems a mismatch with cameras like the Canon EOS R5 and R6.
However, if you can stand the weight and large proportions of the RF 288-70mm f2L USM, it’s capable of delivering very high quality images with an excellent level of detail throughout the focal length range and when wide-open.
You can find the Canon RF 28-70mm F2L USM on Amazon UK.

- Maximum aperture: f/2.8
- Minimum aperture: f/22
- Construction: 16 elements in 12 groups with 3 aspherical and 2 UD elements
- Coatings: Subwavelength structure coating (SWC), ASC (Air Sphere Coating)
- Focusing system: Nano USM
- Minimum focus distance: 28cm from the focal plane throughout the zoom range
- Maximum reproduction ratio: 0.21x at 35mm
- Stabilisation: Yes to 5 stops
- Number of diaphragm blades: 9
- Filter size: 82mm
- Weight: 840g
- Diameter x length: 88.5 x 126.8
Wide and fast, the Canon RF 15-35mm f/2.8L IS USM is an attractive lens for landscape photographers using a Canon R-series camera such as the Canon EOS R5.
Despite having a slightly wider focal length range, the RF 15-35mm f/2.8L is a fraction smaller than its closest match in the EF mount, the EF 16-35mm f/2.8L III USM. A 1mm difference might not sound much, but it’s significant with very wide lenses.
Combined with the closest focusing of 28cm throughout the zoom range to enable foreground elements to loom large, that extra width could be especially useful for landscape photography. And in low light, the image stabilisation, which extends the safe hand-holdable shutter speed by up to 5EV, could be very handy.
Being a Canon RF lens, the 15-35mm f/2.8L has a customisable lens ring, which is helpful for making intuitive adjustments to aspects such as the aperture or exposure compensation.

Best Canon RF lens for wildlife
Yes, there are other wildlife lenses in the Canon RF stable. But the RF 400mm F2.8L IS USM, which is aimed squarely at pro wildlife photographers, retails for £12,440/$11,999 and the RF 100-500mm F4.5-7.1 L IS USM costs £2,979 / $2,799, putting both beyond the reach of most enthusiasts, but the RF 100-400mm F5.6-8 IS USM is a viable alternative.

- Diameter x length (extension from lens mount): 69.2 x 40.1mm
- Weight: 165g
The Canon RF 16mm F2.8 STM is the first ultra-wide Canon RF lens. Its 16mm focal length and full-frame coverage make it a good choice for astrophotography but it can also be used for landscape photography, cityscapes, group portraits and vlogging.
With a maximum diameter of just 69.2mm and at 40.1mm in length, the Canon RF 16mm F2.8 STM seems tiny. You could easily think that its an EF-M mount lens and designed for an APS-C format camera like the Canon EOS M5 Mark II.
As a result of its small size, the RF 16mm F2.8 STM only has one control ring. This can be swapped between being used for manual focusing or to adjust aspects such as the aperture, sensitivity (ISO) or exposure compensation with a flick of the switch on its barrel.
The RF 16mm F2.8 STM offers a minimum focusing distance of 0.13m and a maximum magnification ratio of 0.26x. Other features include a 43mm filter thread and weighs just 165g.
