Modifications enabled with A Firmware Ver. 1.12:
- Remaining battery charge is now accurately detected for Rechargeable Li-ion Batteries EN-EL9a.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*)
