Can Canon Mirrorless Cameras Use EF Lenses?

Yes, with a mount adapter, you can use both your Canon EF and EF-S lenses on Canon's mirrorless EOS cameras. This guide explores the compatibility of EF lenses with Canon mirrorless cameras and explains the options available to you.

Compatibility Across Different Series

The ability to use EF lenses on Canon's mirrorless cameras opens up a wide range of options for photographers. The original EOS M series, introduced in 2012, was one of the first mirrorless cameras from Canon that could be adapted for EF lenses. I personally used an adapter on the EOS M and found it to be a great feature.

The EOS M Series

The EOS M series was engineered to offer compatibility with a vast array of lenses, including EF and EF-S lenses. By using the correct adapter, you can leverage the quality and versatility of your existing Canon lens collection while transitioning to mirrorless technology.

The EOS R Series

The EOS R series, launched in 2018, took compatibility to a new level. This series can also be adapted for EF lenses, with three different types of EF-to-RF adapters available. Each adapter has its unique features, but I prefer the one with a control ring, as shown below.

One of the standout features of adapting lenses for the EOS R series is that you can use both EF and EF-s lenses. This flexibility allows you to carry over the vast majority of your existing lenses, making the transition to mirrorless as smooth as possible.

Introduction to the EF-M Lens Adapter Kit

The Canon EF-M Lens Adapter Kit is a must-have for photographers looking to adapt their EF and EF-S lenses to the EOS-M mirrorless digital camera. This adapter kit allows you to mount these lenses onto your EOS-M mirrorless camera, which has an EF-M lens mount. The kit is fully compatible with all lens functions, including image stabilization and autofocus.

Adapting Lenses: A Comprehensive Guide

When it comes to adapting your lenses, there are several things to consider. Here’s a detailed guide to help you choose the right adapter and understand the process.

Selecting the Right Adapter

There are three types of EF-to-RF adapters for the EOS R series:

The basic adapter without features. The adapter with a control ring for added functionality. The high-end adapter with advanced features and compatibility.

For most users, the second option (adapter with a control ring) is the most practical and versatile choice. It not only provides the necessary compatibility but also adds convenience with the additional features.

Benefits of Using EF-S Lenses

One of the significant advantages of using EF-S lenses on a mirrorless camera is the field of view. EF-S lenses are designed for APS-C sensors, which means they have a narrower field of view compared to EF lenses. However, this also means they can be more convenient to use for close-up shots and in tighter spaces.

Conclusion

With the right adapter, you can seamlessly transition your Canon EF and EF-S lenses to your mirrorless EOS cameras. Whether you're a photography enthusiast looking to upgrade your equipment or a professional transitioning to mirrorless technology, understanding the compatibility and functionality of EF lenses ensures you make the most of your investment.
