The Losmandy Spider Dolly:
This dolly is the most portable professional dolly on the market. Combined with a piece of FlexTrak, the simple 3-Leg Spider (see below) converts your tripod into an inexpensive, extremely portable, tracking dolly. Add a fourth leg, and you can further accessorize it, as pictured here, to be a fully rideable dolly with adjustable center column, foot platforms, and pushbar. Three small cases allow it to be checked through as luggage on an airline.
This spider dolly and track can combine with our Port-a-Jib arm and give limitless camera moves and give you just that extra edge, for a truly professional look.
