Anybody planning to shot at 1200mm equivalent of anything better invest in a decent tripod.
You can barely get away with 600mm equivalent, handheld, with modern image-stabilization sensors. Keep in mind that 1/focal length is a reasonable guideline for shutter speed to avoid blur from the motion of your hand.
