I could rarely bring myself to lug around my Canon full frame camera and lens. So I recently sold all my full frame gear and used the money to buy a Panasonic GX7 micro-4/3 camera and a few lenses. The picture below shows the difference in size between my old system and my new system. The difference in weight is commensurate. What a relief.
