Capture the intricacies of a starry night sky with the new 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! Capture the intricacies of a starry night sky with this 30.3MP Canon EOS Ra mirrorless camera. Equipped with an RF mount that lets you use superior lens designs, it has a Dual Pixel AF system that transforms the shooting experience for novice users and professionals alike.

Designed for Astrophotography
Based on the EOS R, the EOS Ra is an astrophotography-dedicated camera that differs from its general-use sibling in a number of ways to better enable photographing the night sky:
An optical IR cut filter has been placed in front of the CMOS sensor to allow specific transmission characteristics to better enable capturing nebulae and distant galaxies that emit light at the H-alpha wavelength, or 656.28nm. By filtering at this spectrum, 4x improved transmission allows more accurate photography of reddish, diffuse nebulae and other astronomical phenomena in a clearer, more brilliant manner, void of the IR attenuation associated with traditional hot mirrors and other IR-blocking technologies on most cameras.
High-magnification viewing of 30x and 5x is possible using either the rear vari-angle LCD or OLED EVF for clearer, more precise focusing on small and distant subjects, such as stars.
The same white balance presets remain as the standard EOS R; however color reproduction and accuracy may vary depending on lighting conditions and the resulting images may take on a reddish cast. As such, the EOS Ra is not recommended for general photography applications.
Canon RF Lens Mount
Beginning with the lens mount, the EOS Ra supports Canon's line of RF-mount lenses. This mount is characterized by its wide 54mm diameter and short 20mm flange-back distance, which promotes the ability to design lenses that are both faster and smaller than their SLR equivalents. The mount also incorporates a 12-pin electronic contact system for more sophisticated autofocus and image stabilization capabilities. This mount design also lends full compatibility to existing EF and EF-S-mount lenses via an optional EF-EOS R Mount Adapter.
30.3MP Full-Frame CMOS Sensor and DIGIC 8 Image Processor
A large 30.3MP full-frame CMOS sensor is featured and serves as an ideal balance between high-resolution output, low-light performance, and high-speed capabilities. When paired with the DIGIC 8 image processor, the EOS Ra affords a native sensitivity range of ISO 100-40000, which can be expanded to ISO 50-102400 for working in a variety of lighting conditions. Quick continuous shooting to 8 fps is also supported for photographing moving subjects.
Dual Pixel CMOS AF
Dual Pixel CMOS AF offers smooth and fast focusing performance in a similar manner to how a camcorder acquires focus. This system integrates two separate photodiodes within each pixel to provide a broad and dense network of 5655 phase-detection gathering elements across a majority of the image sensor to reduce focus hunting for faster, more direct control of focus placement. When working with still imagery, this focusing system works to acquire focus quickly and accurately, making it ideally suited to shooting and tracking moving subjects so that critical focus is attained with each shot. When shooting video, a Movie Servo AF mode offers smooth and natural focusing when changing from different subjects or different distances within the scene, as well as the ability to specify tracking sensitivity, AF speed, and Face Tracking priority. Benefited by the Touch AF system, rack focus is possible simply by touching elements within the scene on the touchscreen in order to change focus in an intuitive manner. Subject tracking in movies is also heightened due to the Dual Pixel CMOS AF system's ability to recognize subjects and maintain focus when working within changing or cluttered scenery. Additionally, the focus system is sensitive down to EV -6 for working in truly low-light conditions with accurate AF capabilities.
UHD 4K Video Recording and Canon Log Gamma
Designed for multimedia image-maker, the EOS Ra supports UHD 4K (3840 x 2160) resolution recording at up to 30 fps at 480 Mb/s, along with Full HD 1080p shooting at 60 fps and HD 720p at 120 fps for slow motion playback. When recording in-camera, 4K video has 4:2:2 sampling and 8-bit color depth, a 4:2:2 10-bit clean output in ITU-R CT.2020 is possible when using an external recorder.
Integrated Canon Log also allows users to capture flat images with an improved dynamic range of 800%, or 12 stops. This function makes it easier to match cameras in post-production as well as provides the most latitude and potential for color grading. For monitoring, a View Assist function is available, which emulates a graded look for more accurate viewing on the camera's LCD.
Audio can be recorded using the on-board stereo microphone or an optional external mic can also be used via the 3.5mm mic jack.
Dual Pixel RAW
First introduced with the EOS 5D Mark IV, Dual Pixel RAW allows photographers to record all the information the sensor's unique pixel architecture can deliver, providing a way for fine adjustments to be made after the image is taken. These adjustments include focus fine tuning that can help you ever-so-slightly adjust the focus point to bring out extra details, shift bokeh around for improved composition, and reduce the impact of ghosting on your photos. This requires the use of Canon's Digital Photo Professional software.
