Canon 77D, another 24MP DP variation

Review

When shooting movies, the Dual Pixel AF system was quick enough to lock onto most subjects but tended to become confused when new subjects entered the frame from any direction. Lags of up to a second were also common during panning and zooming, particularly in low-contrast lighting and with fast subject movements.

Video quality was similar to the clips we obtained from the EOS 80D, which isn't surprising as this feature has barely changed. The slight differences between Standard and Light (IPB) settings were largely related to their different bit rates. Movies shot with the Light setting were also slightly slower to re-focus and more prone to glitches than those recorded with the Standard setting.

Aside from that, any differences between the HD 1080p and 720p video clips were largely related to the frame resolution and negligible when clips were viewed on a normal HD TV set. Audio quality was similar to that of the EOS 80D we tested. We didn't detect any pick-up of operational noises when zooming and re-focusing while shooting movie clips.
