Generation 4 (G4) transceivers address the challenges brought about by the proliferation of wireless devices using the 2.4 GHz wireless band. Their new architecture results in a greatly improved ability to reject interference from other devices operating in the same band as well as out of band interference. The improvement in performance is quite significant, typically 10x or better interference rejection than previous transceivers. In addition, their lower power consumption doubles the operating time of the HU3 on battery power compared to its predecessor.
New software called “Lens Mapping” matches the focus distances of a lens to a set of five pre-printed Focus Marking Rings. These rings differ in their minimum focus distance from 9″ (.35m) to 6′ (2m). The on-board lens library holds data for 150 lenses. Calibration for a lens change only requires the few seconds to choose the lens from the library. The primary references for the focus puller are the distance marks on the focus rings. The set of focus rings have large, easy to read, distance marks printed on a bright fluorescent background for excellent visibility under all lighting conditions. The rings are automatically illuminated in low light conditions by a pair of white LED’s.
A bright OLED display shows camera, lens, and Hand Unit set-up status. Focus settings can be displayed digitally for Cooke i-Lenses, or any lens which has been calibrated to the unit. Multiple focus marks can be displayed in a new focus display mode called “show”. This mode gives an easy to interpret bargraph representation the distance set by the focus knob and any focus marks entered by the user.
An integrated hand grip and molded focus knob grip imparts comfortable operation. The zoom bargraph shows both the zoom lens position as well as user set end limits. End limits are set with Set/ Reset tactile switches arranged in three groups. An LED in each group indicates when limits have been set.
The HU3 allows for programming camera speed and shutter angle. Power is provided by widely available FM-50 Li-Ion batteries.
The Motor Driver MDR2 accepts commands from the Hand Units connected via the wireless microwave link or cable, and controls up to three digital motors as well as camera functions for both film and video cameras. In addition, it allows wireless control of both the camera frame rate and shutter angle when used in conjunction with the F/X box.
The DM1x and DM2 deliver a unique balance of power, weight, and ruggedness. Both motors have ceramic-coated magnesium housings for minimum weight and metal gears coated with diamond-like-carbon for long life under high torque conditions.
The DM-1X is a high speed and high power motor. It is specifically recommended for driving the focus ring of cinema lenses.
The DM-2 is a smaller and lighter weight motor. It is recommended for driving the zoom and iris of all lenses, and the focus for all but very stiff lenses.
