The Canon EOS 90D is a sleek DSLR also characterized by its high-resolution 32.5MP APS-C CMOS sensor. Combined with advanced image processing, this sensor is also capable of outputting UHD 4K30p and Full HD 120p video, as well as supporting continuous stills shooting rates up to 10 fps. Complementing the imaging capabilities, the 90D sports a vari-angle touchscreen LCD for intuitive control and compositional freedom, and an optical pentaprism viewfinder provides a bright, clear, and realistic viewing means characteristic of the DSLR shooting experience. The sensor and image processor also realize fast performance throughout the camera system, including the ability to shoot continuously at up to 10 fps, record UHD 4K30p video, or record high-speed Full HD 1080p video at 120 fps. The cross-type design of the sensors affords greater accuracy in low-contrast and mixed lighting conditions, and the broad coverage of the 45 sensors is ideal for tracking and maintaining focus on moving subjects. This focusing system offers smooth and fast focusing performance in a similar manner to how a camcorder acquires focus.

Dual Pixel CMOS AF 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. 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. Touchscreen 3.0" 1.04m-dot LCD monitor features a vari-angle design to permit working from high and low angles and the touchscreen design facilitates intuitive control over menu navigation and touch-to-focus operation. Built-in Wi-Fi allows for easy wireless sharing of both photos and movies to a linked mobile device and Bluetooth connectivity permits linking a smartphone or tablet for quick image sharing between devices as well as remote control capabilities when using the Canon Camera Connect app.
