7. LENS ENCODERS
a. MOUNT EXTERNAL ENCODERS
For a proper pairing of external encoders with lens gears, begin by confirming the correct pitch of the gear,
depending on the lens brand. Attach the magic arm to the camera, allowing it to reach the optics with the
encoders. Then, couple them securely, ensuring there is no gap between the teeth, and tighten
accordingly. Finally, connect the cable to the LENS port on KOALA and proceed to step c.
b. LENS WITH VIRTUAL OUTPUT
If your lens is equipped with the 'VIRTUAL' output, you can directly extract data from the internal encoders.
Use the cable specific to the lens brand, connect it to the LENS port on KOALA, and you're good to go.
Proceed to step c.
c. OFFSET AND DIRECTION
1. Decide if the ZOOM reset point (initial value) will be wide or tele and bring it to that position
2. Decide if the FOCUS reset point (initial value) will be at infinity or at minimum and set it to that position
3. Reset the lens from SETUP MENU > RESET > LENS or from SETUP WEB PAGE with “reset LENS” mode
4. On the display, show the data under SETUP MENU > INFO > DATA
5. Move the ZOOM and FOCUS and verify that their values are positive. If they are positive, the procedure
is complete; otherwise, proceed to step 6
6. Invert the mount of encoders or from the SETUP WEB PAGE set “neg” to ZOOM or FOCUS, depending
on the encoder to invert
7. Save your settings from SETUP WEB PAGE with “SAVE DATA” mode
8. Return ZOOM and FOCUS to the reset position and restart procedure from step 3.
NOTE: Unlike OSC, the FreeD protocol does not allow negative values for ZOOM and FOCUS. Therefore,
KOALA will send a value equal to zero in the FreeD data if the ZOOM or FOCUS encoders were to count
negative values.
