The Canon EOS 90D Single Kit with EFS18-55ST Lens is a great balance between still and movie specs for the enthusiast or beginner photographer/videographer that want a little more out of their equipment.
Canon packed a new and improved 32.5 Megapixel APS-C image sensor and their DIGIC 8 image processor into the upgrade to the 80D resulting in 10 fps stills shooting with full autofocus tracking, 4K 25p videos with no crop and Dual Pixel AF enabled! When working with the optical viewfinder, an apt 45-point all cross-type AF system affords fast performance in a range of lighting conditions for tracking moving subjects and working in low light, while the Dual Pixel CMOS AF system benefits live view shooting and movie recording by providing a smooth, natural focusing quality akin to the way a camcorder acquires focus. Touch-to-focus is availed by the large 3.0" 1.04m-dot touchscreen LCD, which also sports a swiveling vari-angle design for working from high and low angles with ease. In addition to the boosted frames per second claim of 10fps vs. 7fps the 90D positions itself as a well-balanced upgrade to the 80D with lots of attention to detail. Exposure and metering have been updated by a 220,000 dot RGB+IR metering sensor with 216-zone (18 x 12) full-aperture TTL metering for more accurate exposure and skintone.
Dual Pixel Autofocus now uses a larger area of the live view frame and now 143 area segments vs. the previous 35 segments of the 80D, and even supports Eye AF servo autofocus to automatically focus on the eyes of a person's face.
The camera's ISO range has also been extended with a calibrated maximum of 25600 (extended 51200) for stills and 12800 (extended 25600) for video proving a 4-stop improvement to the previous generation.
Canon has not forgotten about ergonomics providing both a slightly deeper grip, a new joystick for AF point selection and have also made the 90D slightly lighter and smaller than the 80D.
