Users of the Nikon D40 through Nikon D5000 cameras are probably aware of the fact that these cameras cannot autofocus with all Nikon-compatible lenses. These cameras lack a built-in autofocus motor and, therefore, must rely on the motors inside the lenses in order achieve autofocus.

Nikon has released firmware updates for the D40 and D40x DSLRs.
Nikon D40 firmware updates:
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.
Number of shots possible (battery performance) with EN-EL9a (1,080 mAh)
- Single-frame shooting mode: Approximately 510 shots (with testing according to CIPA standards*)
- Continuous shooting mode: Approximately 2,400 shots (with testing according to Nikon standards*)
