The Miller 944 aluminum studio tripod is designed with single stage legs, 100mm bowl fixing, and extra heavy-duty construction for the utmost strength and torsional rigidity to take a full studio or ENG/EFP workload with confidence. The Mini designation marks the 945 as the shorter version of the 944 with a lower minimum height of 12.0" (30.5 cm) versus the 23.0" (58.4 cm) of the 944, enabling it to capture a lower point of view with heavy cameras.
