Advice on lenses for concert and night photography
The focal length of this type of photography depends on the photographer's taste and the possibilities that the situation offers. During a concert you often have to stand at a distance from the stage and so it is best to use a telelens. With night photography you can capture beautiful landscapes with a wide-angle lens.
Tripod or mount
To take a sharp photo in low light you prefer to use a tripod and remote control. This is only possible if your subject is not in motion and if the situation allows you to use a tripod.
