The Canon XA40 Professional UHD 4K Camcorder is a compact, lightweight camera featuring UHD 4K capture, a 1/2.3" CMOS sensor, two XLR audio inputs, and one mini-HDMI output which fits right into the ENG category for documentary or journalism-style productions.

The XA40's optics include an integrated 20x HD optical zoom and an eight-bladed circular iris for more natural highlights. The camera's pro-style features include Hybrid, Normal, Face Only, Manual Focus, Instant, and Canon's Medium autofocus; fast- and slow-motion recording, full manual control, optical and electronic image stabilization, a 3" touchscreen LCD, user-assignable buttons, infrared mode, and a DIG!C DV 6 image processor with high sensitivity and low noise. The XA40 also has display monitoring features such as zebra, color bars, and test tone.

The camera records UHD 4K30 and Full HD 1080p60 captured to dual SD card slots, and outputs to a mini-HDMI port. The dual SD card slots allow for automatic switching from one card to another, as well as simultaneous recording to both. The camera can output up to 1920 x 1080p 10-bit 4:2:2 video at 59.94 fps via its mini-HDMI output.
