Capture the intricacies of a starry night sky with the EOS Ra camera — Canon’s first full-frame mirrorless camera dedicated to deep sky and night sky photography. Building on the success of the EOS R, the EOS Ra offers 30x magnification in Live View shooting for more accurate focus and roughly 4x more transmission sensitivity of hydrogen-alpha (Hα) rays (656nm) for more vivid, deep-red hues of nebulae, making it ideal for astrophotography enthusiasts. Sharing many of the same advanced features of the EOS R, including a 30.3 megapixel CMOS sensor, a high-precision electronic viewfinder (EVF) and Dual Pixel CMOS AF with 5,655 manually selectable AF positions, the EOS Ra is capable of capturing and pinpointing dim stars that are difficult to see with the naked eye. A Vari-angle LCD touchscreen allows for comfortable composition at any angle and easier framing when shooting vertically, especially when the camera is mounted to a telescope. Featuring 4K time-lapse capabilities, along with high ISO performance, the movement of stars across the night sky can be recorded in brilliant clarity and detail. With a trusted design that’s been specifically enhanced for astrophotography, the EOS Ra proves the age-old adage is true: the sky’s the limit!

Modified Filter for Enhanced Night Sky Recording
Positioned in front of the CMOS imaging sensor, The EOS Ra's infrared-cutting filter is modified to permit approximately 4x as much transmission of hydrogen alpha rays at the 656nm wavelength, vs. standard EOS R cameras. This allows for a higher transmission of deep red infrared rays emitted by nebulae, without requiring any other specialized optics or accessories.
Compatible with EF/EF-S Lenses
The EOS Ra camera is designed to integrate smoothly into existing EOS systems. Engineered to work seamlessly with RF lenses, it maintains complete compatibility with EF and EF-S lenses by using one of three optional Mount Adapters. When using EF-S lenses, the EOS Ra even crops automatically to reflect the APS-C sized sensor the lenses are designed for.
54mm Large Diameter and Short Back Focus
The RF mount on the EOS Ra camera has a large, 54mm internal diameter that enables impressive handling and provides increased flexibility for lens design. And thanks to the camera's mirrorless design, the lens's rear element can be much closer to the image plane. This reduced back focus distance, combined with the RF mount's 54mm diameter, helps facilitate lenses of stellar optical quality and stunning performance while enabling innovative compact camera and lens designs.
20mm Flange Focal Distance with Robustness for Professional Use
All RF lenses feature a 20mm flange focal distance, which is the distance from the lens mount to the surface of the image sensor. This flange focal distance balances the benefits of short back focus with the engineering requirements necessary for mount stability. Accordingly, the RF mount's flange focal distance ensures excellent optical performance while maintaining the mount rigidity and camera durability necessary for real-world operation.
12 Pins for Quickly Communicating Large Amounts of Information
With a robust 12 pin connection between the camera and the lens, the EOS Ra camera and RF lenses are able to communicate at a higher speed, transmitting a larger amount of data and information for incredibly fast AF, plus enhanced image stabilization and optimization.
Variety of Mount Adapter Options for Expanded Compatibility with EF/EF-S Lenses
Mount adapters, such as the Mount Adapter EF-EOS R, deliver seamless connections between the EOS Ra camera and EF and EF-S lenses with all functions intact. Offering L series level weather and dust sealing, the Mount Adapter EF-EOS R is even compatible with EF extenders like the Extender EF 1.4x III to extend your camera's optical reach. With an entire arsenal of EF and EF-S lenses at your disposal, the Mount Adapter EF-EOS R and other mount adapters ensure endless creative possibilities for the EOS Ra camera.
Beyond enabling use of EF and EF-S lenses on the EOS Ra camera, the Control Ring Mount Adapter EF-EOS R and the Drop-in Filter Mount Adapter EF-EOS R add functions that open up a number of new possibilities for creative image capture. The Control Ring Mount Adapter EF-EOS R adds a control ring like those found on RF lenses, providing the same level of control to your EF and EF-S lenses and supporting the same setting configuration regardless of lens. The Drop-in Filter Mount Adapter EF-EOS R enables compatibility with EF and EF-S lenses and includes drop-in filter capability for use with circular polarizing filters or variable ND filters. This enhancement enables compatibility with numerous lenses regardless of their front diameter, and makes filter use possible with lenses like the ultra-wide EF 11-24mm f/4L USM lens or the tilt-shift TS-E 17mm f/4L lens which cannot accept a filter on the front.
30.3 Megapixel Full-frame CMOS Sensor
The EOS Ra is Canon's first astro-dedicated mirrorless camera that features a Canon-developed and produced 35mm full-frame CMOS sensor with approx. 30.3 effective megapixels. It employs the DIGIC 8 Image Processor to enhance the speed of operations across the board. This means fast, efficient performance and phenomenal image quality for big prints, impressive 4K video and more.
High-speed Focusing in Approx. 0.05 sec.
The EOS Ra camera's highly responsive Dual Pixel CMOS AF system features an incredible 5,655 manually selectable AF positions and can deliver sharp focus within approximately 0.05 seconds. This means fast action can be captured and focus can be maintained with speed, accuracy and ease.
4K 30p, Full HD 60p, HD 120p
The EOS Ra camera offers advanced recording features such as 4K at 29.97 fps, Full HD at 59.94 fps and HD at 119.9 fps. Helpful functions include distortion correction during recording and Movie Digital IS. Additionally, video can be recorded during still photo shooting by simply pressing the Movie Shooting button. Beautiful time-lapse videos can also be created in 4K simply and easily with the dedicated Time-lapse Movie mode – ideal for capturing movement of the stars across the night sky.
0.5-type OLED EVF with Approx. 3.69 Million Dots
The EOS Ra camera features a high-precision 0.5-inch OLED (Organic Light-Emitting Diode) EVF with approx. 3.69 million dots and a 23mm eyepoint. Displaying a bright image and extensive shooting information that rotates with the camera, the viewfinder excels in bright conditions where viewing the camera's LCD may prove difficult.
The EOS Ra's electronic viewfinder has been created to provide a bright, sharp and colorful 100% view of the subject at hand. Equipped with an aspherical lens, the EVF shows a crisp and vivid image with minimal aberration or distortion, even when the eye moves off the center of the visual field.
The EOS Ra's EVF has a bright, 23mm-high eyepoint design that creates a generous 30mm space between your nose and the rear of the viewfinder. This makes it easy to compose and view images in the viewfinder with or without glasses. A dioptric adjustment of -4 - +2 means it's simple to change as needed to suit various users.
The EVF's 0.5-inch OLED based display features approximately 3.69 million dots for an incredibly sharp and detailed image that makes it easy to check focus and view the extensive image data that's displayed.
Lightweight and Compact
With a compact, lightweight and comfortable design, the EOS Ra camera reflects Canon's decades of experience designing and manufacturing cameras. With an intelligent layout of buttons, dials and screens, the EOS Ra is intuitive for new users and feels familiar to EOS users, offering the advanced features and nimble operation EOS users demand.

The EOS Ra camera gives you the choice of standard, full-frame viewing in 5x or 30x magnification - this is the first Canon EOS camera with 30x capability. This feature provides you with a tool for extremely precise focusing upon small stars and other astrophotography subjects. The EOS Ra camera is also able to display the 30x magnification through the electronic viewfinder, along with its LCD screen for Live View operation.
Comfortable and solid in the hand, the EOS Ra camera features a rigid yet lightweight magnesium alloy chassis that enhances body durability while shielding the camera from electromagnetic radiation and heat. It also has a tempered front panel for internal rigidity.
The EOS Ra camera has a silent shutter feature that uses an inaudible electronic shutter instead of the camera's focal-plane shutter.
USB Charge Compatible
The EOS Ra camera is compatible with the USB Power Adapter PD-E1 for in-camera charging via USB. Featuring an industry standard USB-C connector, the USB Power Adapter PD-E1 makes for easy charging without the necessity to remove the battery from the camera.
