my D90 has shown a couple of faults recently. first one is the flash...it failed to go off a couple of times (the on-camera one) and i had to pop the flash down and pop it back up to get it go off. the battery was on full charge and it was the first flash as well.
the second problem actually worried me a bit, i was shooting a few random pictures then, the camera refused to open the shutter, the normal beep when focus was acquired and then nothing, turn the camera off and turn it on, the same thing, and did again the same thing, until the third time and it was ok.
anyone got any explainations?
