Canon EOS 5DS R camera is the one of the best camera ever. its very very useful for photography as well as cinemography. I just complete my short film with canon 5D camera. it was best experiance by using it. awsome crearity. zooming, closeup shots, I feel very lucky to use this. I can used for full movie also. canon 5d battery backup is also good.
but its much expincive to buy. if you have a budget to buy it. please buy it with any arguments.its really awsome for photography or shooting too.
