Firmware Version 220.127.116.11 incorporates the following fix:
Fixes a phenomenon in which the focal length may not change when the control ring’s function is to control the step zoom, and the control ring is turned slowly, click-by-click. (In AUTO, SCN, or Movie mode, the default function for the control ring is to control the step zoom.)
Please note that this phenomenon does not always occur with every affected product.
Firmware Version 18.104.22.168 is for cameras with firmware Version 22.214.171.124 or Version 126.96.36.199. If the camera's firmware is already Version 188.8.131.52, it is not necessary to update the firmware. Please note that, once the camera is updated to the latest version, it cannot be restored to a previous version.
