Lens Data Displays
Power/sleep function
• To turn on the LDD press the POWER/SLEEP button. To save power the LDD has a sleep mode.
If the lens barrels do not move, and the LDD buttons are not operated for about five minutes, the LDD goes to
sleep. The LDD screen can also manually be put to sleep by briefly pressing the POWER/SLEEP button again.
To wake it up, move any lens ring or briefly press the POWER/SLEEP button again.
• To power up the LDD-FP, set the ON/OFF switch to ON. If no information changes, the LDD-FP falls asleep
automatically after about two minutes. To wake it up, move any lens ring.
Note: The SLEEP status is indicated on both displays by a slowly blinking LED.
• To turn off the LDD, depress the POWER/SLEEP button for about 3 seconds.
• To turn off the LDD-FP, set the ON/OFF switch to OFF.
Start up
When either Lens Data Display is powered up and detects an LDS Lens, the lens barrels need to be turned so
that the system can recognize the lens ring markings. If lens motors are used, this will happen automatically
when the motors are calibrated. If lens motors are not used, this can be done by hand. Slowly turn the lens
barrels until the lens scales appear on the display.
Handling the focus marks
Setting • Press the SET button to set a focus mark.
Deleting • Move the focus ring until the focus mark lines up with the focus index line.
• Press the DELETE button.
• To delete all focus marks, hold the DELETE button depressed for 3 seconds.
Moving • Turn the focus ring until the focus mark to move aligns with the focus index line.
• Press the SET button until the mark disappears and keep it depressed.
• Turn the lens focus ring.
• Release the SET button.
Renumbering • Move the focus ring until the focus mark lines up with the focus index line.
• Press the UP or DOWN buttons.
Note: When renumbering one focus mark, the Lens Data Displays do not update the numbers on focus marks
already set, so beware that duplicate numbers are possible.
Hyperfocal distance
A small grey line in the focus scale shows the hyperfocal distance. When the lens is set to the hyperfocal
distance, everything from half the hyperfocal distance to infinity is in focus.
Circle of confusion
The circle of confusion (coc), used for the calculation of the depth of field and the hyperfocal distance, can be
selected on both Lens Data Displays. The default setting is 0.025 mm (1/1000”).
• On the LDD, DIP switches located under the rear coverplate of the LDD change the coc value.
• On the LDD-FP, the coc value can be changed with a sub-menu.
Unit of measurement
The Lens Data Display will automatically show the same unit of measurement (m or ft) as the LDS Lens. The unit
can be changed:
• On the LDD, by depressing either the UP button (m) or DOWN button (ft) while powering up.
• On the LDD-FP, by setting the UNIT selector either to M, LENS or FT.
