How many kilograms is a digital camera?

One of the lightest digital camera is Casio EXILIM EX-M1 with its weight 86 g, but heaviest body has Canon EOS-1Ds Mark III - 1385 g.

With Canon body one you need some lens too, so with heaviest lens Canon EF 400mm f/2.8 L IS USM (5375 g), the total weight could be 6 kg and 760 g.

So broadly we can say, that digital camera is 0-7 kilograms.
