Review Excerpt

  • Dual Pixel CMOS AF delivers full-time continuous autofocus (with phase detect at every pixel in framing area) for video and Live View still shooting; Full HD (1080p) video recording with pro-level features and quality; Improved resolution and good high ISO performance; Excellent Wi-Fi remote shooting with full exposure controls; 3-inch articulating LCD touchscreen.

  • Image quality only improved slightly over 60D; Dynamic range still lags behind competing models; May not feature enough upgrades to convince people to step up from 60D.
