About Lens Updates:

Upgrading or downgrading your lens to a different firmware version might enhance the unit’s overall performance and stability, and could also improve some of the lenses’ features (a good example would be faster autofocus speed).

In order to apply a firmware properly, other than the one already installed, you should check that the lenses are connected to the camera body, copy the compatible update on a memory card, and insert it into the camera.

From the device’s menu, browse to the Firmware Upgrade section, and enable the new firmware. Since each device has various ways to enter the update mode and particular steps that should be taken for a successful upgrade, you must make sure that you read the product’s installation guide.
