Originally, when we designed version one of this product, it was to be used in the underslung position on cranes. However, because of the ability to use it for shooting a time-lapse, people started to use it in the over-slung position. In this position, the centre of gravity is higher. This forces you to ensure your base is secure because as your setup gets higher, the more unstable it becomes.
In order to make the head more suitable for shooting in the over-slung position, we have made a few modifications. The first thing that we have changed is the motor position. The Pan axis motors are now inverted, which enabled us to lower the mounting area by 3.75" to 1.75". If you are wanting it even lower and do not need the cables to pass through, you can lower it to a 1/4" by removing the stand offs. To do this, you need to remove the four screws on the base plate and then remove the four screws on the mounting plates. Once you have done this, you can attach the base plate directly to the column on the head to achieve the 1/4" configuration.
Another modification we made is an adjustable Tilt support arm so you can lower the camera platform by 4". There are 5 different heights you can choose between using the available lock pockets. This helps you fine tune the height you desire.To lower, simply loosen the screw on the tilt arm and fine tune the height.
In its lowest configuration, it is about 8" shorter than the height of version one, which is almost half the height of version one. However, if you are wanting to have access to the original size, if you are using a larger setup, such as a long lens or matte box, you simply loosen the screw and adjust to the height you desire. By raising the height, you can gain access to more movement if desired when shooting with a larger camera configuration.
For example, when a stripped down DSLR is attached you have full access to the movement. However, when you attach a matte box, you will need to raise the head to achieve the clearance height needed.
One great feature of this system is the ability to order either the 500 series motor or 1000 series motor. The standard motor is the 500 series and is what has been used with version one of the head. It is a good all around motor, however, if you are either shooting on a long lens or primarily shooting time-lapse, you may want to look at getting the 1000 series motor. Basically, the difference is that the 1000 goes half the speed with twice as much torque as the 500. This allows you to do very precise moves.
There are a few different mounting options. The first is to use the Kwik Release System. The second is to mount directly to your sliders and cranes. Use the bolts provided in each case. For the CineSlider, use the four screws included with CineSlider . To mount to the KC-Cranes, use the bolts and wing-nuts provided with the Rev 2. You can also use a ball mount to attach it as well. You can then mount the head to anything with a ball mount, such as a tripod, Pocket Jib or Shuttle Pod.
