Hello guys. After the firmware update, how can i set the mirror lock-up without AC power adapter, because i can not open the page if its not conected in the AC power adapter. because i think after the update, we can use with the camera battery also! Thanks for help!
Go to mirror lock up in the menu with the spanner (we call it a spanner in the UK - is it called a wrench in the US?). To start mirror lock up, press the shutter release. To finish mirror lock up, turn the camera off.
Worked fine on mine. If it doesn't work it may be that the firmware upgrade is somehow incomplete.
The update to the manual says the function can be selected "when a fully charged battery is inserted in the camera". I guess Nikon may have put a check in there to block the function if the battery power is getting low.
