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. Additionally, built-in Wi-Fi and Bluetooth connectivity allow you to pair mobile devices with the camera to wirelessly transfer files for sharing your photos and movies online. 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. 

For working with telephoto lenses fitted with extenders, 27 of the points are capable of focusing down to f/8 and the center dual cross-type offers increased precision at brighter aperture values. 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. 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. 

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.  The pentaprism type optical viewfinder offers 100% frame coverage for high compositional accuracy when shooting at eye level. Additionally, further aiding shooting with the viewfinder, AF points and mode, compositional grids, a horizontal electronic level, and other assistive Features can be displayed during use. 

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.

The EF-S 18-135mm f/3.5-5.6 IS USM lens, which provides a 28.8-216mm equivalent focal-length range. One ultra-low dispersion element is featured in the optical design, along with one aspherical element, to reduce chromatic aberrations throughout the zoom range as well as limit spherical aberrations and distortions for increased clarity and sharpness. The lens is also distinguished by a NANO USM focusing system, which offers a combination of a fast, stills-optimized ring-type Ultrasonic Motor and a smooth, silent video-optimized stepping motor for all-around focusing performance to benefit multimedia image-makers.  

Additionally, also aiding both photo and movie recording, an Image Stabilizer system compensates for up to four stops of camera shake for sharper handheld shooting.
