The Canon LEGRIA HF S21 is the high-end model in the line up that features a built-in 64GB memory. Opening up the side LCD display, we found two SD card slots, Video Snap, Display/Battery Info and record/play buttons, and component, AV and remote connectors.
The display is touchscreen and allows you to access the menu and settings conveniently. You can also enable subject face auto tracking by pointing it on the screen.
At the top is a sliding cover that reveals a hot shoe for optional external light or stereo microphone attachment.
A mini USB and HDMI out connectors are on the right of the HF S21.
