So Im looking at a great night image (1.30am), tried experimenting at home and discovered that when I try to take a BULB exposure shot pointed at something 99 percent in the dark the camera refuses to work with AUTOFOCUS, assumably because AF on the lens will not focus without something with light on it to focus on ?

If I switch to MANUAL MODE and MANUAL FOCUS on the LENS it will fire off a shot and hold the exposure time for as long as I like, but I cant MANUALLY FOCUS the shot anymore than the camera can with the lens on AF....i end up with a nicely exposed shot but completely out of focus.

So, how do people get shots like this ? Had the same issue trying to shoot lightning strikes at night.

Got me caffudled.
