Center columns are important accessories for the Systematic range of tripods, giving extra height and making framing adjustments easier. The geared versions allow even finer height adjustment, and, with their anti-rollback mechanism, are more secure during raising and lowering of heavy photographic equipment. Gitzo's a wide range of top quality tripods and heads were exported to more than 54 countries! In 1992, Gitzo became part of the Vitec Group – a multinational holding company specialized in supporting professional photographers, broadcasters and filmmakers. Gitzo's unfailing standards have helped to maintain the company's worldwide reputation for excellence in the photographic industry.
