The Pico Dolly is an affordable solution to give you a stable video camera platform for smooth tracking shots. The base and axels are made of aluminum and the wheels feature high quality ball bearings for smooth video. With the three 1/4-20 female thread positions you're able to attach accessories such as articulated arms, ballheads, and various mounts to customize the dolly to fit your needs. The wheels are mounted to adjustable axels which can be pivoted so the dolly can travel either straight or in circles. When using ballheads (sold separately) or camera mounts the Pico Dolly can support smart phones, small camcorders, action cameras, mirror-less cameras, and DSLRs.
