U is for... USB

If you want to trigger an EOS DSLR camera remotely, but don't want to invest in a full Wi-Fi system, then a USB cable (provided in the box with the camera) will also work. For more range, longer USB cables can be used, although anything over ten meters is probably better served by using Wi-Fi. To access remote shooting, simply plug the camera into the computer with the USB cable and open Canon's EOS Utility software. Select 'Camera settings/Remote shooting' and you'll then be able to control the camera directly from the computer. The EOS 5DS, 5DS R, and 7D Mk II are compatible with SuperSpeed USB 3.0, thus enabling faster transfer of image files to computers when shooting tethered.

USER-DEFINED SETTINGS


User-defined settings on EOS cameras include options for altering the preset picture styles, enabling you to create your own style by adjusting the Sharpness, Contrast, Saturation, and Color Tone parameters via the Picture Style menu option.

UDMA


The EOS 7D Mk II is capable of shooting up to ten full 20.2-megapixel photos in a single second, recording images as Raw, JPEG, or both at the same time. Infinite JPEG or 31 Raw files can be captured at 10fps without any loss in performance (when using a UDMA 7 card), and the shooting rate can be customized to suit the pace of the subject being photographed, with images recorded to dual CF and SD card slots.
