The introduction of Canon’s RF mount in 2018 marked a significant shift in the world of photography and videography. As Canon’s latest innovation, the RF mount has been making waves in the industry, offering a new level of creative freedom and versatility to photographers and videographers alike. But have you ever stopped to think about what Canon RF actually stands for?
The Origins of Canon RF
To understand the significance of Canon RF, it’s essential to take a step back and examine the history of Canon’s efforts in the photography and videography space. Canon, a Japanese multinational corporation, has been a pioneer in the imaging industry for over 80 years. From its humble beginnings as Seikikogaku Kenkyusho (Japan’s first optical company) to its current status as a global leader in imaging technology, Canon has consistently pushed the boundaries of innovation.
In the 1950s, Canon introduced its first rangefinder camera, the Canon I, which marked the beginning of the company’s journey in the photography space. Over the years, Canon continued to innovate, introducing new camera systems, lenses, and technologies that revolutionized the industry. The introduction of the EOS (Electro-Optical System) camera system in 1987 was a significant milestone, offering a new level of autofocus and metering capabilities.
The Evolution of Canon’s Mount Systems
Before the introduction of the RF mount, Canon had two primary mount systems: the EF mount and the EF-M mount. The EF mount, introduced in 1987, was designed for Canon’s EOS camera system and offered a wide range of lenses and compatible cameras. The EF-M mount, introduced in 2012, was designed specifically for Canon’s EOS M mirrorless cameras.
However, with the rise of mirrorless cameras and the increasing demand for faster, more versatile, and more compact lens systems, Canon recognized the need for a new mount system that could meet the evolving needs of photographers and videographers.
Enter the RF Mount
In September 2018, Canon announced the introduction of the RF mount, a new lens mount system designed specifically for Canon’s EOS R mirrorless cameras. The RF mount was designed to offer a new level of creative freedom, with a shorter flange distance (the distance between the rear of the lens and the camera’s sensor) and a larger mount diameter.
The RF mount’s design enables faster communication between the lens and camera, allowing for faster autofocus, improved image stabilization, and enhanced video capabilities. The RF mount also offers a new level of compatibility, with a growing range of RF lenses and adaptors that enable compatibility with EF and EF-M lenses.
What Does Canon RF Stand For?
So, what does Canon RF stand for? According to Canon, the “RF” in Canon RF stands for “R-Fujinon,” a name that pays homage to Canon’s heritage and commitment to excellence. The name “R-Fujinon” is a nod to Canon’s early days, when the company produced high-quality Fujinon lenses.
In an interview with DP Review, a Canon representative explained that the “RF” name was chosen to reflect the company’s commitment to innovation and excellence. “We wanted a name that would reflect the DNA of Canon, and ‘RF’ seemed like the perfect fit,” the representative said.

What is Canon RF, and how does it differ from Canon EF?
Canon RF is a new lens mount system introduced by Canon, designed specifically for their full-frame mirrorless cameras. It differs from the traditional Canon EF mount in several ways, including a shorter flange distance, a larger diameter, and a new communication protocol. This allows for faster data transfer, improved autofocus, and the ability to create lenses with new and innovative optical designs.
The RF mount is designed to take advantage of the capabilities of Canon’s mirrorless cameras, providing a more compact and lightweight system that is ideal for both stills and video shooters. With the RF mount, Canon has been able to create lenses with unique features, such as the RF 28-70mm f/2L USM, which offers a constant f/2 aperture throughout the zoom range. Overall, the RF mount represents a significant step forward in lens design and technology.
Is Canon RF a replacement for Canon EF, or will both systems coexist?
Canon RF is not a direct replacement for Canon EF, but rather a complementary system that offers a new range of possibilities for photographers and videographers. Canon has stated that they will continue to support and develop the EF mount, and that EF lenses will remain compatible with Canon’s mirrorless cameras through the use of adapters.
In fact, Canon has already released several EF-RF adapters, which allow EF lenses to be used on RF mount cameras with full compatibility and functionality. This means that photographers who have invested in EF lenses can continue to use them with their new mirrorless cameras, while also having the option to explore the new RF lenses and their unique features.
What are the advantages of Canon RF lenses over Canon EF lenses?
Canon RF lenses offer several advantages over Canon EF lenses, including faster autofocus, improved optical performance, and new and innovative features. The shorter flange distance of the RF mount allows for the creation of lenses with new optical designs, which can provide improved image quality, reduced distortion, and increased sharpness.
Additionally, the RF mount’s new communication protocol enables faster data transfer between the lens and camera, which allows for faster and more accurate autofocus, as well as improved video performance. RF lenses also tend to be more compact and lightweight than their EF counterparts, making them ideal for photographers and videographers who need to travel light.
Will Canon RF lenses be compatible with Canon EF cameras?
No, Canon RF lenses are designed specifically for Canon’s mirrorless cameras and are not compatible with Canon EF cameras. The RF mount is a new and unique design that is not backwards compatible with EF cameras.
However, Canon has developed EF-RF adapters that allow EF lenses to be used on RF mount cameras, but there is no adapter available that would allow RF lenses to be used on EF cameras. This means that photographers who want to use RF lenses will need to use them on a compatible RF mount camera.
What is the roadmap for future Canon RF lens development?
Canon has announced a roadmap for RF lens development that includes a wide range of lenses, from ultra-wide zooms to telephoto primes. The roadmap includes a total of 32 lenses, with several already available and more to be released in the coming years.
Canon has stated that they will focus on developing lenses that take advantage of the unique features of the RF mount, including its short flange distance and fast communication protocol. This means that photographers can expect to see innovative and high-performance lenses that are designed to take their photography and videography to the next level.
Can I use Canon RF lenses for video production?
Yes, Canon RF lenses are designed to be compatible with Canon’s mirrorless cameras, which are ideal for video production. The RF mount’s fast communication protocol enables fast and accurate autofocus, which is essential for smooth and professional-looking video.
Additionally, many RF lenses feature advanced video-centric features, such as a clickless aperture ring and a minimized focus breathing effect. This makes them ideal for videographers who need to capture high-quality video with a shallow depth of field and precise control over the aperture.
Is the Canon RF system open to third-party lens manufacturers?
Canon has not officially announced whether the RF mount will be open to third-party lens manufacturers. However, it’s worth noting that Canon has a long history of partnering with third-party manufacturers to develop EF mount lenses.
If the RF mount is opened up to third-party manufacturers, it could lead to a wider range of lenses being available, including specialized and niche lenses that may not be feasible for Canon to develop on their own. However, at this point, it’s unclear whether Canon will open up the RF mount to third-party manufacturers, and photographers will have to wait and see what the future holds.
