The advantages of the CANON RF lens and why you should change it

Canon has one of the most comprehensive lens lineups for all genres of photography and filmmaking. Canon EF lenses for EOS digital SLR cameras have a long history of great performance, but the new Canon RF lenses for EOS R have emerged in recent years. full-frame mirrorless cameras have grown considerably.

With so many choices now available, how do you know which lens system best suits your needs? Why should you consider moving to the RF line for your full-frame mirrorless lens if you currently have dependable favorites from the EF line? How to choose? We’ll go over the primary benefits of RF lenses as well as some extra things to think about.

RF mount lenses have a 12-pin connection, compared to EF mount lenses that have 8 pins. This increases the speed and volume of data transmission between the camera body and the lens, resulting in extremely fast autofocus, real-time digital lens optimization (DLO), and improved image stabilization. DLO uses the lens’ built-in memory capacity to allow it to store data on any aberrations that occur, which means it can quickly and automatically correct these aberrations while shooting. DLO can also be utilized during continuous shooting without impacting the rate or quantity of shots taken.

Both the Canon EOS R5 and Canon EOS R6 feature Integrated Image Stabilization (IBIS). IBIS works in tandem with the lens-based Image Stabilizer to provide coordinated control and reduce camera shake up to an incredible 8-stop shutter speed for select RF lenses. This allows you to capture great footage and longer exposures, even while shooting handheld.

Canon’s EOS R full-frame mirrorless system is built around the RF lens mount. RF lenses use the same optimized 54mm inner diameter as Canon’s EF lens line, but the flange distance (the distance between the lens mount and the camera sensor) has been more than halved to just 20mm.

Light strikes the sensor straighter now that the big components are closer to the sensor than possible, reducing ghosting and flare. This improves image quality and sharpness, especially at the frame’s boundaries.

Another benefit of adopting the RF lens system is that you can get larger apertures for a given focal length. For example, the RF 28-70mm f/2L has a constant f/2 aperture across the standard zoom range compared to the equivalent EF 24-70mm f/2.8L II USM.




The large elements used in fast RF lenses require powerful autofocus motors. The new Nano USM motors provide an excellent balance between fast focus for still images and smooth, near-silent focus transitions when shooting video. This is ideal for shooting movies, especially when recording audio with an on-camera microphone.

RF lenses offer an excellent balance between high performance and compact, lightweight design. For example, the Canon RF 70-200mm f / 2.8L IS USM lens was designed to achieve the popular 70-200mm zoom range in just 146mm (at its shortest length). This makes the lens about 27% shorter and 28% lighter than its EF equivalent. When paired with Canon EOS R compact bodies, RF lenses are an excellent choice when you’re on the go, such as travel, street, and wildlife photography.

If you’ve already invested in EF lenses and switched to full-frame mirrorless, the good news is that they can still be paired with the EOS R body system using the EF-EOS R Lens Mount Adapter. The adaptor gives you more creative flexibility while maintaining complete compatibility and performance.

Keep in mind, however, that extending your lens selection to include the ground-breaking new RF lenses lets you fully use the RF mount’s potential. RF lenses are designed to deliver superior quality and speed with a performance system optimized for EOS R cameras.

RF lenses also offer new innovations such as the RF 85mm f/1.2L USM DS, which is the first lens with Canon’s original Defocus Smoothing (DS) coating. This allows you to achieve a significant soft and smooth bokeh effect, further expanding the possibilities for portrait photography.

RF lenses are equipped with a lens control ring that allows for quick intuitive shooting – offering customizable control of shutter speed, ISO, or exposure compensation. This unique feature allows you to fine-tune these settings without having to look away from the viewfinder.

The good news is that you can also take advantage of this new feature when shooting with EF lenses on EOS R system cameras by using the EF-EOSR control ring mount adapter.

The creative possibilities in photography and filmmaking are unlimited with the expanding selection of Canon lenses available and ongoing innovation!

Explore RF lens choices that have been developed to maximize performance with your EOS R mirrorless camera to get the most out of it.
