In fact, the weight of a lens has no effect on the camera's weight. For example, a camera that weight 1100g with no lens attached, will weigh 1100g with any kind of lens attached. It's simple quantum physics.
I was speaking of the the whole assembly body +lens. An OM-D M-5 camera and a Oly 12-40 pro or a 12-60 Panasonic lens would be lighter. There are like some DX combinations like D500 and Nikon 16-80 that would be a bit lighter.
