The Panasonic Lumix GX7 has a retro-themed design, a trend which was popularised by Fujifilm with its X series of cameras. However, the GX7 has a markedly different look and design approach.br br The GX7 comes in two colours -- silver and black -- of which we got the former. It has a magnesium alloy body and the metallic portion is visible on the top of the camera with the front and rear sides covered in rubber and plastic.
