Chrosziel Studio Rig, VariLock 2 Single

For smooth and precise focus moves due Chrosziel's fluid damping module and gear units and bearings with the lowest tolerances: It allows play and jerkfree focus moves even for permanent direction changes. Chrosziel abstains from using switchable gear boxes for the sake of play-free preciseness. Instead, they use two gear boxes for the different focus markings of film and video lenses. Film lenses, prime lens and "Cine style" video lenses typically display an adjustable range of 200-degrees from close-up to infinity. The Studio Rig Cine translates the rotation on the hand wheel in a way to lens focus ring that approx. one turn covers the range. The focus of the video lenses rotate only approx. 100 to 145-degrees between close-up and infinity. For similar operation and preciseness, the Studio Rig Video's gear unit extends the resulting angle of rotation of the video lenses. Further adjustments are made by the use different gear diameters. All gear drives can be easily mounted without tools. The three modules of the lens manufacturers are available. The Studio Rig basic unit comes with hand wheel 1 with fluid damper, scale ring and focus lever and clamping unit for the 15mm video standard. The hand wheel with VariLock 2 Module allows easy setting of two mechanical stops and free wheel. The VariLock 2 wheel can be attached instead of first or the second hand wheel.
