  2. Improves a phenomenon in which the background is not blurred when performing slow panning with the IS (Image Stabilization) mode set to Mode 2 or Mode 3.
Firmware Version 1.0.9 is for lenses with firmware up to Version 1.0.7 If the lenses' firmware is already Version 1.0.9, it is not necessary to update the firmware.
