If you’re a Canon user in Canada looking to upgrade your gear, you’ve likely come across the debate: Canon RF vs. EF lenses. With Canon’s shift to mirrorless technology, many photographers are wondering whether to invest in RF lenses or stick with their trusty EF glass. In this guide, we’ll break down the differences between Canon RF and EF lenses, helping you decide which one is best for your needs.
Understanding Canon RF and EF Lenses
Canon EF Lenses: The EF (Electro-Focus) mount was introduced in 1987 and has been the standard for Canon DSLR cameras for decades. These lenses are compatible with Canon’s full-frame and APS-C DSLR cameras. EF lenses are known for their wide selection, affordability, and compatibility with older camera bodies.
Canon RF Lenses: RF (Revolution Focus) lenses are designed for Canon’s new mirrorless EOS R-series cameras. Introduced in 2018, RF lenses offer superior optical quality, faster autofocus, and a more compact design due to their shorter flange distance. RF lenses are built for the future of photography, with advanced features like better image stabilization and enhanced low-light performance.
