Motorized Camera Slider
In the following please find the technical details about the motor-operated slider. As a start, I offer the system in two lengths: 75 cm (30") and 100 cm (40"). Respectively at the ends and in the centre, the guide rails have a one-quarter inch (on request three-quarters inch) thread and so are coupeable to every quick-release plate commercially available.
The 75 cm version including dolly, control unit and batteries weighs 3.1kg (6.8 lbs). The 100 cm version weighs 3.7 kg (8.2 lbs).
The control system and battery are combined in one device. The speed is infinitely adjustable. Clockwise/left-handed rotation. The energy (12 volt) comes from eight commercially available AA batteries.
The housing of the dolly is made of aluminium, CNC-milled. The surface has a black powder coating. At the top side, there is a three-eights thread screw, where every tripod/video head may be screwed on.
The slider may be operated in a horizontal, vertical and overhead way. The maximum camera weight in horizontal operation is approx. 6 kg (13 lbs), in vertical/diagonal function approx. 3,5 kg (7.7 lbs) (including head).
At first, the system is operated by two exchangeable motors. The motors are exchangeable against each other in just a few steps. The slow motor is intended for time-lapse photography and for macro video, the fast one for slow realtime video recordings. The motors stop automatically at the end of the guide rail. A further “faster” motor is planned.
Speed slow motor: fast 4 min/m (40") - slow 30 min/m (40")
Speed fast motor: fast: 33 sec/m (40") – slow 6 min/m (40")
价格和国产差不多,差别在哪里?
