AF at night
 

This might be a noob question....

I got a tripod and started taking long exposure night shots. It's easy to work with if there are light at the other end that AF can lock on. However, I was at the beach and there aren't too many bright light, at least none that AF can lock on. And it was way too dark and at an awkward position for me to look and do a manual focus. I'm not entirely confident in doing a manual focus anyways, and it was pretty dark.

How do you guys do it?

to be honest? manually, its a long exposure anyways

Switch to manual, set it to hyperfocal distance, or set it to the line where infinity is.
