Function-enhancing firmware Ver.2.21

January 30, 2013


Adds Auto setting to Dynamic Range Compensation function

In addition to the existing Weak, Medium and Strong settings, the camera now provides an Auto setting that automatically adjusts the level of dynamic range compensation for a given subject.



Improves Noise Reduction function at high ISO

Thanks to a new algorithm, the camera’s Noise Reduction function can reduce chromatic noise more effectively during high-sensitivity shooting at ISO 2500 or higher, when the noise reduction level is set at MAX.



Add New Playback Zoom function to center a subject captured with Target Selection function

In the Playback Zoom mode, a subject captured with the AE/AF Target Selection function is automatically centered in the magnified on-screen image, even when it is positioned off-center in the original image.

The snap focus distance at the time of shutter release can now be saved to the ADJ. lever or the Fn button.
The setting can be changed without having to go the menu screen.
