Petrol Bagsâ„¢ Cambio convertible equipment bag/camera support system is an industry first. A carry-on sized smooth-rolling camera carrier that transforms into a lightweight support system for small video camcorders, Cambio allows users to travel lighter, avoiding waiting for baggage, and set up quickly once theyâ€™ve arrived at the location. Within the Cambio is an expandable (up to 56â€/142cm) rigid, nickel-plated center steel column. The column can accommodate cameras weighing up to 9.9 lbs. (4.5kg) â€“ which allows for use of the Video DSLR cameras, as well as more traditional HD DV models. Cast magnesium lever clamps ensure fast and sure column adjustment. The bag is equipped with a patent-pending frame and axle support trolley with integral handle and camera platform with 75mm ball head mount adapter. An optional lightweight micro-fluid head allows for quick attachment and conventional pan and tilt movements. The freestanding Cambio is braced by a self-latching extendable aluminum double-bar tube leg. The leg expands and retracts quickly and easily with just the touch of the legâ€™s latch paddle. When using the support system, Cambioâ€™s patented heavy duty, jitter-free wheels and axle can be chocked to prevent rotation, adding extra stability.
