Firmware Version 184.108.40.206 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.
