This new USB filter from Starlight Xpress is unique in that it does not require a separate power supply when used with USB control - the high performance DC gear-motor runs entirely from the USB supply and consumes less than 100mA. It is also capable of operation from a serial input or from a switched hand controller, both of which power the wheel from a small dry battery.
Starlight Xpress Filter Wheel & OAG Review
Light and slim with thumbscrews for quick and easy swapping of filter disks without tools.
Quiet in operation and the Hall-Effect 3-bit encoded positioning gives precise filter locations (not serially sequential) so you can easily swap between any filters without accidentally losing the wheel position.
A variety of threaded adapters are available starting with: T thread, SCT thread and Takahashi 72mm thread.
To change adapters simply use a small screwdriver to release three stainless screws then lift off the adapter flange. Each flange can be rotated to any angle before locking down so the wheel and camera can be orientated into the optimum position.
Another premium-quality product from a British manufacturer!
