Built around a newly developed 45MP full-frame CMOS sensor, the EOS R5 offers both high-resolution stills and video output and the fine-tuned DIGIC X image processor complements this with a wealth of speed. Sensitivity from ISO 100-51200, which can be expanded to ISO 102400, suits working in a variety of lighting conditions while quick continuous shooting up to 12 fps with a mechanical shutter, or silent 20 fps with an electronic shutter, is ideal for working with moving subjects.

Benefitting more than just stills, the 45MP full-frame sensor also enables impressively high-resolution DCI 8K 30 fps raw video recording internally along with 4K recording up to 120 fps in 4:2:2 10-bit with Canon Log. HDR-PQ recording is possible, too, in-camera HDR production and external recording, via the HDMI port supports a clean 4K output at up to 60 fps. Both All-I and IPB compression options are available, along with the ability to use Dual Pixel CMOS AF when shooting at up to 8K raw.

An updated Dual Pixel CMOS AF II features 1053 selectable focusing points, which cover approximately 100% of the image frame for wide and even coverage. This focusing system 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 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.

Subject tracking has also been benefitted through the use of Deep Learning technology, which helps to gradually refine the focusing system's ability to quickly and accurately recognize both people and animal subjects. This technology also supports the more refined eye, face, and head detection functions, for both people and animals, that are well-suited for portraiture applications.

A first for EOS cameras, the R5 incorporates five-axis sensor-shift image stabilization that compensates for up to an impressive eight stops of camera shake for truly effective compensation of camera shake to suit handheld shooting with slower shutter speeds. This stabilization system also works in concert with lens-based optical image stabilization for both native RF lenses and adapted EF lenses.
