Panasonic Lumix DMC-GX7

The Panasonic Lumix DMC-GX7 announced in August 2013, is a Micro Four Thirds compact mirrorless interchangeable lens camera. It was Panasonic's first Micro Four Thirds camera with a built-in in-body stabilization system (IBIS) and has a built-in EVF (add-on EVFs are no-longer supported).[1] Panasonic uses 2-axis in-body stabilization allowing the use of shutter speeds 1 to 2 stops slower than without stabilization,[2] compared to the 4 to 5 stops of improvement offered by Olympus' 5-axis stabilization.[3]

Successor

Although the Panasonic GX8 has the succeeding number, it is a model not related to the GX7 line. The true successor of the GX7 is the Panasonic GX80/GX85, which is called GX7 mark ii in some markets. The Panasonic GX80/GX85 has the same 16mp sensor, but without the AA-filter. It also has greatly improved IBIS and comes with a new shutter mechanism. The tilting viewfinder is no longer available. This came back though with the Panasonic GX9, which is called GX7 mark iii in some markets.
