1 Improved flash firing for backlight conditions when the flash is set to [Auto].
2 Changed the focus bar display of the external AF*. When the shutter release button is pressed half-way (focus lock), the focus bar for the external AF will stop at the position where the focus is locked.
3 Changed the image stabilizer control. Using [P] / [A] / [S] mode, the camera will take a picture without the image stabilizer function when the shutter speed is less than 1 second, even if [Camera Shake Correction] is set to [On].
4 Corrected the phenomenon below. A black line may appear at the top of the image taken with [Hi-Cntrast B&W] for [Image Settings].
* The focus bar of the external AF will be displayed when the camera is set as follows. [Optional AF Distance Display] > [On]; [Full Press Snap] > [On]; [Snap Focus Distance] > [Auto]; [Focus] > either of [Multi AF], [Spot AF], or [Snap].
* The focus bar of the external AF will disappear if the camera goes into Macro mode.
