When this procedure has been completed, an icon with the letter c appears on the right

hand side of the lens name, indicating that the lens has been calibrated (Fig 10).

Return to the Menu Screen (fig 7), and press Ring to select a ring (A – E) for metric and Ai

– Ei for imperial) to match the close focus of the lens. The tables below show the near

focus distances for both the rings calibrated in imperial and metric units.

Note that

any focus ring can be used with any lens.

The ring can be chosen to best use the

mechanical range of the focus knob. For example, if the closest subject distance is 6’

while the lens has a close focus of 18”, the Ei ring would allow maximum focus knob

travel – covering infinity to 6’, while the Bi ring would allow focus down to 18”. In the

latter case, the focus knob movement from 6’ to 18’ would not be used.

7. The Operating Mode is changed by using the Nav key to select Mode and then

pressing Choose. The four modes are:

• Normal

• Snorkel

• Custom

• 3D

The Normal mode is defined by having each of the motor channels controlled by the

corresponding channel of the Hand Unit. Within this mode there are two ways the zoom

control can operate, Normal and Video.

The Normal Zoom mode means that the Hand Unit controls the

position

of the zoom

motor and this position is shown on the zoom bargraph display. Limits can be set to the

zoom range using the Set/Reset keys.

The Video Zoom mode allows the MDR to control the internal motor of video lenses.

Instead of displaying the position of the zoom motor, in this mode, the zoom bargraph

display indicates the

velocity

of the zoom motor. Therefore limits on the zoom range

cannot be set. A video zoom cable is required to connect the MDR2 to the video lens.
