The EPD-41A-D01 is an operating unit for adjusting the correct focus from a distance with a cable. Conceived for shooting footage from helicopters or vehicles, it is also useful for recording concerts and nature or animal images. As the modern 4K technology requires a high degree of precision, the design of the unit is geared to fast and exact operability. The star-shaped centre element guarantees easy handling of the operating unit even under difficult conditions, for instance with gloves.
