What camera is best used for shooting concerts/live performances?
First and foremost you’ll need a camera that allows you full manual control. Freezing action is a function of shutter speed. Shutter speed is a product of light, lens aperture (f-stop) and ISO. In concert situations where the light is usually dim you’ll have to “open up” your lens and increase your ISO. As you increase ISO, image quality begins to suffer. Noise Reduction circuitry helps but its no cure-all. As you “open up” your lens, its performance declines – most all lenses give their best results at between f5.6 and f11. A lens wide open, say at f2.0 or f2.8 will admit the most light but the edges won’t be as sharp and you’ll see some light fall-off from center to edge. As in all things there are no solutions only trade-offs. Turning now to my trusty FotoSharp “Day & Night Exposure Guide” we find: Indoor sports, circus – floodlit suggests: f2.8 @ 1/125 @ ISO 800 f4.0 @ 1/60 @ ISO 800 f2.8 @ 1/250 @ ISO 1600 f4.0 @ 1/125 @ ISO 1600 School stage/auditorium suggests: f2.8 @ 1/30 @ ISO
