The G4’s upgraded 3-axis OIS 2.0 system, which improved motion compensation from 1° to 2°, also carries over to the G5’s primary camera as does the separate color spectrum sensor, which is an RGBC (red/green/blue/clear) and IR sensor that measures the color temperature of a light source and is supposed to improve the performance of the auto white balance system. While the focus speed of laser AF is roughly equivalent to phase detect AF (PDAF), we’ve found PDAF to work more reliably. The laser AF system uses a modified proximity/light sensor with an 850nm laser that makes time-of-flight calculations to quickly determine focus distance. It uses a Sony IMX234 Exmor RS sensor with a native 16:9 aspect ratio and a hybrid autofocus system that combines laser AF and contrast AF. The primary rear camera is the same as the G4’s. Where the G3 added laser autofocus and 3-axis optical image stabilization (OIS), the G5 adds a second, wide-angle camera on the back. The G3 and G5 are both ticks: same sensors, same optics, new features. The G2 and G4 are both tocks: new sensors, new optics, new features.

LG has settled into a tick-tock cadence for camera upgrades.
