When you look at a dark night sky there's not enough light. The camera can't find any contrasting objects to focus on. You need to turn autofocus off and wait 10 minutes or so for your eyes to adjust. Then you manually focus the camera. Of course you use a tripod and a remote release and don't bother if it's windy out.
Here's an easy to read article on autofocus... HowStuffWorks "How Autofocus Cameras Work" |
Yeah it's night time and some times even evening shots that it doesn't want to shoot. It will focus on the thing in trying to take a picture of but then it doesn't beep to let me know it's ready, and no matter how long you hold the button it doesn't want to snap the pic. Even in situations where I was in a fairly lit parking lot at night it has trouble sometimes. It may just be something in the settings, such as spot metering vs center weighted focusing or something, idk. I have to play around with it more. I also have to figure out why it doesn't want to do bracketing.
