Canon EOS Ra

Canon EOS Ra

This customized version of the Canon EOS R, designed exclusively for individuals interested in shooting the night sky, has an optical infrared cut filter in front of the sensor, allowing for the capture of distant nebulae and other cosmic phenomena with the highest level of clarity.

By incorporating a specific filter into the EOS R’s architecture, the EOS Ra offers about four times the transmission and sensitivity to H-alpha (656.28nm) wavelengths, which is ideal for displaying nebulae and other scenes without infrared interference, resulting in enhanced color neutrality.

Additional enhancements include the addition of a 30x live view magnification option, which allows for better focusing precision on distant targets while working with either the EVF or the back LCD. Aside from this handful of variances, the EOS Ra and EOS R are equipped with an identical set of basic characteristics that enable them to capture images with high resolution and fine detail.

The EOS Ra is equipped with a full-frame CMOS sensor with a resolution of 30.3MP and a DIGIC 8 image processor for superior image quality. When these technologies are combined, they provide a wide sensitivity range of up to a native ISO 40000, quick continuous shooting at up to 8 frames per second, and UHD 4K30 video recording.

The sensor also has a sophisticated Dual Pixel CMOS AF technology, which employs 5655 customizable points to swiftly and precisely acquire focus. This focusing technology is very sensitive down to EV -6, allowing it to be used in extremely low-light environments.

Aside from being ideally suited to the UHD 4K video recording capabilities, the camera is also equipped with Movie Digital IS to decrease camera shake, built-in Canon Log gamma for increased dynamic range, and 4K 10-bit 4:2:2 output through HDMI to provide even better color customization.

Besides the performance characteristics, this camera has been created from the ground up and has a high-resolution 3.69m-dot OLED electronic viewfinder for crisp and brilliant eye-level viewing, as well as a built-in flash.

As an alternative, the device also has an LCD touchscreen with 2.1 million dots at the back of the device that can be adjusted to function from high and low angles. A Multi-Function bar, which can be customized to suit the user’s preferences and allows for straightforward adjustment of shooting parameters, is also available. In addition, because this is a camera designed to handle the harshest circumstances, the magnesium alloy body is dust and moisture-resistant.
