I have a question: I typically use AutoFocus to focus a shot, but I have been doing a lot more night photography recently. I now use LiveView a lot more so I can optically zoom and manual focus (which is great if you have enough ambient light). However, I am trying to shoot scenes which require long exposures in darkness and in LiveView, everything is just black. I need to know: what solutions are there for me, in order to be able to focus my subject in darkness? I have never used an AF-assist beam, but I am pretty sure its only good for maybe 10-15 feet. I thought about using a high f-stop, but I would not know how to properly expose a 30 sec+ shutterspeed shot in "bulb." Any suggestions?
