C-Stand with retractable sliding leg (0.3–1.2m extension) for enhanced stability on uneven surfaces. Load capacity up to 10kg, working height 1.3–4.2m; available from Matthews, Avenger, Kupo.
Technical Details
Standard versions reach working heights between 1.3 and 4.2 meters with a maximum load capacity of 10 kg on the main arm. The sliding leg features a pneumatic or mechanical locking mechanism and can be extended infinitely between 0.3 and 1.2 meters. The characteristic knuckle arm with grip head allows for 360-degree rotation and carries loads up to 5 kg in a horizontal position. High-quality models from Matthews, Avenger, or Kupo use powder-coated steel constructions and weigh between 8.5 and 12 kg.
History & Development
The basic construction of the C-stand originated in Hollywood studios in 1927; the sliding leg was first introduced in 1987 by Matthews Studio Equipment as the "Sliding Leg Extension." This innovation solved the problem of ground clearance at low camera angles and on uneven set floors. In 1994, pneumatic locks were integrated, and in 2003, Avenger developed the "Auto Pole System" for even more precise adjustment. Modern variants since 2015 offer quick-release mechanisms and weight-optimized carbon fiber components.
Practical Use in Film
On Ridley Scott's "Blade Runner 2049" (2017), DoP Roger Deakins used sliding leg C-stands for the iconic ground lights in the city scenes – the extended leg stabilized the heavy LED panels at 15-degree angles. In Emmanuel Lubezki's work on "The Revenant" (2015), the sliding legs allowed for the positioning of reflectors on uneven forest ground without visible tripod legs in ultra-wide shots. The extendable foot prevents tipping in wind or vibrations and reduces space requirements by up to 40 percent.
Comparison & Alternatives
Compared to standard C-stands, the sliding leg variant offers 60 percent more stability at low angles but costs 40-70 Euros more. Baby stands do not achieve the necessary ground clearance, and combo stands are too heavy for mobile use. Modern alternatives like the Manfrotto Avenger A2033L or Matthews Hollywood Century C-Stand 40" offer comparable functionality. For extreme precision, DoPs are increasingly relying on motorized variants with remote control, available since 2019.
