I am thinking of buying one of these small and cheap ($20~) laser pointers to use it as a focusing aid in the dark. They produce a fairly small and very bright red dot that can be aimed at the point you want to focus. The range can be up to hundreds of meters, depending on the device.
I like to take night pictures of monuments, and i believe this could help to get the best focus.
Has anyone tried such a device in the field ?
Thanks a lot
