Its 20.1MP 1" CMOS sensor uses a stacked design, which pairs with the DIGIC 8 image processor to realize especially fast focusing performance, full-resolution shooting at up to 20 fps, and UHD 4K30p video recording. Optically, the G7 X Mark III houses a 4.2x zoom lens, which covers a 24-100mm equivalent focal length range for wide-angle to short-telephoto fields of view. An f/1.8-2.8 maximum aperture range suits working in difficult lighting conditions as does an Optical Image Stabilizer, which compensates for the effects of camera shake. The camera's slim design also incorporates a 3.0" 180° tilting touchscreen LCD and has both Bluetooth and Wi-Fi for wirelessly connecting to a mobile device. 20.2MP 1" Stacked CMOS Sensor and DIGIC 8 Processor Featuring a large 20.1MP 1" stacked CMOS sensor, along with a DIGIC 8 image processor, the G7 X Mark III offers notable imaging performance characterized by high speed and low noise. The stacked sensor design, coupled with the DIGIC 8 processor, affords especially quick focusing speeds, up to 20-fps continuous shooting, and UHD 4K30p and Full HD 120p video recording. Also unique, this camera supports vertical video recording along with live streaming through YouTube, via a Canon iMAGE GATEWAY account, and the ability to use an external microphone and clean HDMI output further enhances recording quality.
