The Firmware update improves the following issues:
* The picture sharpness is better under low contrast conditions.
* Noise is reduced when working at high sensitivity ISO setting.
* The flash control is better at close range with a non-ADI control lens.
Apparement Sony avait poussé le traitement d'image un peu trop fort, la correction est conseillée.
