The camera also has Wi-Fi with NFC, PC sync port, highlight and shadow control, and a 'silent mode' which uses the electronic shutter only. Video shooting include focus peaking, zebra pattern, luminance level adjustment, and cinema gamma presets. An optional 'interface unit' adds five SDI and two XLR terminals, and permits 10-bit 4:2:2 output with time code.[2]
