A:Answer Dear Lumix customer, the DMC-GX850 was introduced to market in January 2017 and Panasonic GX85 was launched in April 2016. There is not a big difference between these two cameras, but it gives an advantage to the younger GX850, especially in sensor tech. The GX850 has 10.0 fps continuous shooting, the GX85 has 8.0 fps continuous shooting. It also has a higher dynamic range (13.3) and wide bracketing range (±5 EV). The GX85 also has some better functions, all lenses are stabilized, is better for flash photography, it has an electronic viewfinder which gives better framing and control, it has a faster mechanical shutter, better battery life, longer flash coverage and better high ISO performance.
