Panasonic has released new firmware for its Lumix DC-G80/81/85 and DC-GX80/GX85 camera models that eliminates the whirring noise caused by the in-body stabilization system while in stand-by mode. Firmware version 1.2, in both cases, also reduces the impact of the noise during video recording, which previously would encroach on the audio of scenes shot in quiet situations. Now in stand-by mode the body is silent whereas before it was really quite noisy.
The new firmware also adds Dual IS 2 to the G80/81/85 when the camera is used with the company’s Leica DG Vario-Elmar 100-400mm F4-6.3 ASPH lens. Dual IS 2 is Panasonic’s improved stabilization system that uses the IS features of both body and lens combined to increase the amount and flexibility of the motion compensation.
