The smallest, lightest Steadicam that can be used with a support arm and vest is the Merlin. It is light enough to be hand held with cameras weighing up to about 5.5 pounds (2.5 kg), and may carry cameras up to about 7 pounds (3.2 kg) when used with the arm. The Merlin may be folded and carried in comparatively small spaces such as medium-size camera bags. In its lightest configuration, the Merlin weighs just 12.5 ounces (0.35 kg). Photographers who shoot with HDSLR cameras that combine still and motion photography most often work with the Merlin. Since the Merlin has no facility to carry a separate monitor, cameras suitable for it must have built-in monitors.
