This download provides software for upgrading D40 A firmware to v1.12. The camera’s B firmware must be Ver. 1.11 to upgrade A firmware to Ver. 1.12. Be aware that proper operation of your D40 is not guaranteed with the combination of A firmware Ver. 1.12 and B firmware Ver. 1.00 or Ver. 1.10.
The following issues has been resolved in A firmware version 1.12
With firmware Ver. 1.11 and earlier, the number of images that could be captured (battery performance) when an EN-EL9a was used was less than when an EN-EL9 was used. By upgrading A firmware to Ver. 1.12, EN-EL9a performance is maximized so that more images can be captured (battery performance) when an EN-EL9a is used than when an EN-EL9 is used.
