All Canon EOS R System cameras, whether they are full-frame or APS-C format, are mirrorless cameras featuring exactly the same advanced RF lens mount. This means that if you opt for the EOS R7 or EOS R10, or even the EOS R50 or EOS R100, you can take full advantage of the entire range of outstanding RF lenses. In addition to lenses with cutting-edge focusing technologies and optical quality, the RF mount provides hugely greater data transfer speed and bandwidth between lens and camera, enabling advanced AI-powered autofocus acquisition and tracking with incredible speed and precision, new levels of image stabilisation, real-time lens optimisation, and many other advances.
With the introduction of the EOS R7 and EOS R10 came new RF-S lenses specially designed for RF mount cameras with APS-C sensors. The RF-S 18-45mm F4.5-6.3 IS STM standard zoom, with a 35mm equivalent effective focal range of 29-72mm, is comparatively tiny with its retractable design, weighing a mere 130g, while the RF-S 18-150mm F3.5-6.3 IS STM delivers an even greater zoom range – 35mm equivalent effective focal range 29-240mm – and still weighs only 310g, making it a highly versatile, all-in-one lens for everyday shooting and travel photography.
Other compact, lightweight and affordable full-frame compatible favourite RF lenses include the Canon RF 16mm F2.8 STM, which on the EOS R7 and EOS R10 gives a still generous wide field of view equivalent to a 25.6mm lens on a full-frame body. The Canon RF 35mm F1.8 MACRO IS STM works brilliantly as a standard prime, with a 56mm effective focal length on APS-C EOS R System cameras, complete with optical image stabilisation and a 0.5x macro magnification factor. The Canon RF 50mm F1.8 STM is an excellent portrait lens, combining an effective focal length of 80mm on an APS-C camera with a fast f/1.8 aperture for a tight depth of field. For travel and street photography, RF 28mm F2.8 STM gives an effective focal length of 45mm when paired with the EOS R10 in a light, compact pancake design.
You can also use the wide range of EF and EF-S lenses on APS-C R System mirrorless cameras, with no loss of quality or functionality, thanks to the range of EF-EOS R Mount Adapters.
