Canon Brings Improved Autofocusing to New Rebel and 77D

February 15, 2017

Supply-side economics may be malarky, but trickle down is definitely the order of the day at Canon. The company launched a pair of new DSLRs that benefit from technologies, such as Dual CMOS AF and the new DIGIC 7 processor, that originally appeared on pricier models.


The new 77D features a 24-megapixel APS-C-sized CMOS image sensor and DIGIC 7 processor. It’s capable of an ISO range of 100-25,600 and high-speed shooting up to 6 fps with focus fixed on the first frame. The camera incorporates Canon’s Dual Pixel CMOS AF autofocusing technology and has 45 all cross-type points.

The camera offers an RGB+IR metering sensor that employs Color Detection AF to detect skin tones. According to Canon, when a skin tone is detected, AI Servo AF starts off on skin-colored AF points, then tracks the subject based of the original AF point’s color information, maintaining focus on the person as they move. There’s also an anti-flicker function to compensate for flickering light sources.

Additional features of the 77D include:

  • electronic image stabilization in movie mode
  • HDR and time-lapse movie modes
  • built-in Wi-Fi, NFC and Bluetooth
  • full HD video recording
  • 1/4000 sec. max mechanical shutter speed
  • built-in flash
  • 3-inch vari-angle touch screen display
  • 820 shot battery life

The 77D ships in April for $900 for the body (pre-order); $1,049 with the new EF-S 18-55mm lens (pre-order) and $1,499 with the 18-135mm IS lens (pre-order).

Rebel T7i

The T7i brings several firsts to the Rebel series. It’s the first model with Dual Pixel CMOS AF and the the first Rebel with a 45-point, all cross-type AF system within the optical viewfinder. Beyond that, the Rebel T7i very closely mirrors the 77D’s feature set.

The T7i packs a 24-megapixel APS-C-sized image sensor with a DIGIC 7 processor and ISO range of 100-25,600. You can hit up to 6 fps in continuous mode with AF fixed on the first frame.

Additional features include:

  • creative filters for stills and video
  • Wi-Fi, Bluetooth and NFC
  • full HD video recording
  • battery life of up to 820 shots
  • 3-inch, vari-angle touchscreen display
  • electronic image stabilization for movies
  • new on-camera guide to represent how switching exposure modes changes an image

Look for the T7i in April. It has a body-only price of $750 (pre-order); with the new EF-S 18-55mm f/4-5.6 IS STM lens for $900 (pre-order) and with the EF-S 18-135mm f/3.5-5.6 IS STM lens for $1,299.

The kit lens for the Rebel is also getting an update that shaves about 20 percent of the size off of its predecessor. The lens offers image stabilization good for up to four stops of correction and can be purchased for $250.
