D70s Focus Assist light problem

[ajmall]

I was using my D70s in a night club last night taking crowd and DJ shots. Obviously in a dark situation the focus assist light is paramount yet the light would only come on when the centre focus area was selected. The camera/lens would just try and focus but it couldn't due to the low light.

Anyone else heard of this or experienced it? It's never happend before to me.

ive had it happen on my canon eos 350d.. but that was in pitch black, so i kinda assumed it to..

sorry i didn't explain it well enough - when the camera/lens tried to focus, it was too dark because the assist light didn't come on.

It could be the assist light is focused on where the center area is so you can get enough light strength to assit in focusing. You might just use your center selector for focusing so you can use the assist then just recompose with focus lock. Or if you are worried with exposure or something with the lock then after you get focus just flip to manual focus so the camera doesn't adjust. I do this all the time with my f100 and macro work.

ah ok, never thought of that though it helps if i take the pictures quickly and i'm pretty sure it's worked before without using the centre AF area... i'll read the manual and see
