Initialize Lens with the T.H.C.

When to Initialize

Normally, the lens initializes when you power on the camera or swap the lens. However, sometimes the lens may not operate properly when first connected to the camera.

Manually reinitialize the lens in the following situations:

• The lens is not behaving as expected.
• The focus or zoom was manually changed.
• The focus range was changed using the focus range limiter switch on the lens (only applicable to multi-focus zone lenses).

NOTE: Failing to perform the initialization sequence after any of the situations listed above may result in undefined behavior.

Initialize

Press and hold the Initialize button on the T.H.C. for two (2) seconds.
