it's Nikon or Canon cousins and lot less than the Nikon AFS 500F4 lens that I carried on a tripod with Gimbal head and Nikon D3 attached. Yes, you are right , this lens weighs close to 6.5lbs and I don't need that( I still need to work). That is why I am getting a Bigma that weighs only 4lbs and use this lens where only a short walk is involved.
