Camera Overview — Canon EOS Ra
Key Features — Canon EOS Ra
Astrophotography-Modified Sensor: A specially designed infrared filter allows approximately 4x more hydrogen-alpha light transmission than the standard EOS R, making nebulae and emission objects far more visible in captures.
30.3MP Full-Frame Sensor: A 35mm CMOS sensor with DIGIC 8 processing delivers high-resolution files across a broad ISO 100–40000 range, giving astrophotographers meaningful latitude in low-light conditions.
5,655-Point Dual Pixel AF: Canon's Dual Pixel AF system covers the frame with 5,655 selectable focus points, supporting Eye Detection AF and subject tracking for reliable performance beyond astrophotography use.
4K Video with 10-Bit HDMI Output: 4K video at up to 30fps can be output at 10-bit depth via Mini HDMI, with Canon Log and HDR PQ color profiles available for post-production flexibility.
Vari-Angle LCD: The 3.15-inch, 2.1M-dot touchscreen tilts and rotates fully, making it practical to compose shots when the camera is pointed at awkward angles toward the sky.
3.69M-Dot Electronic Viewfinder: A high-resolution EVF with 60Hz refresh rate provides a detailed, real-time live view useful for manual focusing on stars and other dim subjects.

Description — Canon EOS Ra
The Canon EOS Ra is a full-frame mirrorless camera built on the Canon RF mount platform, purpose-modified for astrophotography use. Its 30.3MP sensor is paired with the DIGIC 8 image processor, and an ISO range of 100 to 40000 supports shooting in very low-light environments. The autofocus system provides 5,655 Dual Pixel AF focus points alongside Eye Detection AF and subject tracking for versatile use beyond nighttime imaging.
For video, the EOS Ra captures 4K at up to 30fps (24fps, 25fps, and 30fps supported) with 10-bit color depth, Canon Log, and HDR PQ profiles. The 3.15-inch vari-angle LCD resolves at 2.1M dots, and the electronic viewfinder reaches 3.69M dots at a 60Hz refresh rate. The weather-sealed magnesium alloy body weighs 660g and measures 135.8 x 98.3 x 84.4 mm.
Connectivity includes Wi-Fi, Bluetooth, USB-C, Mini HDMI, and both 3.5mm headphone and microphone jacks. Storage is handled via SDXC and SDHC cards, and the camera runs on the LP-E6N battery, rated for 370 shots per charge.
