In the years since Canon first introduced the EOS R in 2018, it’s greatly expanded the RF family of cameras and lenses.
However, Canon has a huge selection of EF lenses that many photographers invested a lot of money in, so it makes sense to use a Canon EF to RF adapter to use older EF lenses on a newer RF body.
It’s not just a good decision to use EF glass for seasoned photographers who have a bunch of EF lenses on hand, either. If you invest in an RF body, buying an EF lens (or two or three) is a great way to save money while still getting excellent image quality.
With that said, let’s examine the practicality and benefits of using Canon EF lenses on RF camera bodies. I’ll provide some insights from my personal experience as an avid photographer who has successfully navigated the Canon EF to RF transition.

Canon EF to RF Compatibility and Adapters
Transitioning from Canon EF to RF is a straightforward process, thanks to Canon's well-designed adapters. These adapters bridge the gap between the two lens systems, allowing you to seamlessly use your EF lenses with the latest RF camera bodies.
Canon offers several official adapters that ensure full compatibility and performance. The most popular is the Canon Mount Adapter EF-EOS R (shown above), which retains all autofocus, image stabilization, and lens correction functionalities. Another noteworthy option is the Canon Control Ring Mount Adapter EF-EOS R, which adds a customizable control ring to the adapter, enhancing user experience by providing easy access to settings like aperture or ISO.
Third-Party Adapters
You can find a plethora of third-party EF-RF adapters on online platforms like MPB.
If you’re looking for alternatives, reputable third-party adapters are also available. Brands like Viltrox, Lensbaby, Meike, and Fotodiox offer cost-effective solutions, though they may not always match the performance and reliability of Canon’s official adapters. When choosing a third-party adapter, it’s essential to read reviews and ensure that the specific adapter you select is known for maintaining autofocus speed and accuracy.
Pros and Cons of Different Adapters
While Canon’s official adapters are highly reliable and maintain the full functionality of EF lenses, they come at a higher price point. Third-party adapters, on the other hand, are more budget-friendly but can sometimes lead to slower autofocus or reduced image quality. Ultimately, the choice of adapter depends on your budget and performance requirements.
Of course, as I always say, buying used photography gear is a great way to limit your expenditures while still getting great equipment. When shopping at an online platform like MPB, for example, you can find great used EF lenses, RF cameras, and Canon EF to RF adapters to make the two work well together. In other words, you might be able to afford the pricier Canon gear if you prioritize buying used in the first place!
Performance and Image Quality When Switching from Canon EF to RF
One of the primary concerns when using EF lenses on RF bodies is whether the performance and image quality will be compromised. Through extensive use, I’ve found that EF lenses perform admirably on RF bodies, often delivering results comparable to native RF lenses.
Ben Harvey has found the same, too. Check out his assessment of how EF lenses perform on RF bodies in the video above.
Autofocus Performance
Autofocus performance is a critical aspect of photography, and Canon’s EF lenses do not disappoint when used with RF bodies. The autofocus speed and accuracy are generally maintained, thanks to the advanced electronics in the adapters.
In most shooting conditions, the difference in autofocus performance between EF and RF lenses is negligible. However, for high-speed action photography, native RF lenses do offer a slight edge.
Image Quality Considerations

When it comes to image quality, EF lenses hold their own remarkably well. Sharpness, color reproduction, and overall image fidelity remain high. Some minor issues, such as slight vignetting or distortion, can occur, but these are typically correctable in post-processing.
In my experience, the quality of images produced by EF lenses on RF bodies meets professional standards, making them a viable option for serious photographers.

Understanding the benefits and drawbacks of using EF lenses on RF bodies is crucial for making an informed decision. Here’s a breakdown of what to expect when making the EF to RF transition.
Benefits of Using EF Lenses on RF Bodies
Cost Savings: Investing in new RF lenses can be expensive. By using existing EF lenses, you can save a significant amount of money while still enjoying the advanced features of RF bodies.
Lens Variety: The EF lens lineup is extensive, offering a wide range of focal lengths and specialized lenses. This variety provides flexibility and creative freedom, which is especially beneficial for photographers with diverse shooting needs.
Familiarity: If you’ve been using EF lenses for years, there’s a level of familiarity and comfort that comes with continuing to use these lenses. This can lead to a smoother transition to RF bodies.
Potential Drawbacks and Limitations
Size and Weight: EF lenses, particularly the professional-grade ones, tend to be larger and heavier than their RF counterparts. This can make the camera setup bulkier and less portable.
Compatibility Issues: While most EF lenses work seamlessly with RF bodies, there can be occasional compatibility issues, especially with older lenses. It’s essential to test your lenses with your RF body to ensure they meet your performance expectations.
Possible Loss of Some Functionalities: Certain advanced features available with RF lenses, such as the control ring on RF lenses or the faster communication between lens and body, may not be fully replicated with EF lenses and adapters.
Practical Tips and Recommendations for Your Lens Needs

Maximizing the benefits of using EF lenses on RF bodies involves a few practical considerations…
First, use Canon’s official adapters whenever possible. Yes, they’re more expensive, but they offer maximum compatibility and performance. Save some cash and buy used, and you can outfit yourself with a nice kit for less!
Second, regularly update the firmware. Keep both your camera body and lenses updated with the latest firmware to enhance performance and compatibility. While you’re at it, test your gear before heading out on an important shoot. Testing your EF lenses with a Canon EF to RF adapter and an RF body is essential so you know everything functions as it should.
Recommended EF Lenses
Several EF lenses are known to perform exceptionally well on RF bodies. Some of my favorites include the following:
Maintenance and Care Tips
Of course, gear is only part of the equation. You also need to care for your gear to get the best performance. That being the case, it’s important to clean your Canon EF to RF adapters regularly so dust and debris don’t accumulate inside and negatively affect performance. The same goes for your lenses and camera bodies!
Store your gear properly, too. When not in use keep your lenses, adapters, and cameras in a protective case to prevent damage. While you’re at it, handle your gear with care when you’re transporting it from one location to the next. Also be mindful when mounting and dismounting lenses and adapters - their electronic contacts are delicate!
Buy Canon EF to RF Gear (and Save Money, Too)
Using EF lenses on Canon RF bodies is a practical and cost-effective solution for many photographers. The transition from EF to RF can be smooth and rewarding, allowing you to leverage your existing lens collection while enjoying the benefits of Canon’s latest camera technology. With the right adapters and a few best practices, you can achieve outstanding results and continue to capture stunning images.
And, as I mentioned earlier, you can pair Canon’s legendary EF lenses with its newer RF bodies for less money if you buy used. But don’t buy used photography gear from anyone…
I’ve used MPB many times over the years to buy used gear, and I’ve never been disappointed with the quality of the gear I got in the mail. Part of the reason for this is that each item is thoroughly inspected and graded by MPB’s team of professionals, and their findings are listed on each item’s listing page. That means you know exactly what you’re getting and what condition it will be in when it arrives.
But peace of mind is part of this equation, too. MPB offers a seven-day return window in case the gear you get isn’t what you bargained for. There’s also a six-month warranty available on many of MPB’s cameras and lenses, so you can rest easy that your investment is covered.
On top of all that, you can sell your old gear to MPB or trade it in. Either way, you can use the gear you no longer need to help offset the cost of Canon EF to RF adapters and other goodies for your new-to-you kit.
Whether you’re a professional photographer or an enthusiastic hobbyist, embracing the versatility and performance of EF lenses on RF bodies can enhance your photographic journey. Canon EF lenses gained epic popularity for a reason; there’s no need to spend more money on more modern lenses if older EF lenses do the trick!
