Generally speaking, the larger the sensor, the better it is for low-light photography. While you can’t go wrong with a full frame camera in low light, your mileage will vary greatly depending on the lens you use, and you can still get great low light results with a crop sensor camera, with the right lens. An APS-C or even Micro Four Thirds camera also offers advantages such as portability and smaller lenses, so it’s all about weighing your needs. Fortunately, modern digital camera sensors have become increasingly efficient at gathering light, allowing ever higher ISO settings and usable images with minimal noise in very low light.
Of course, when shooting in poorer conditions, you can minimize noise by allowing more light to enter the sensor, either by increasing the exposure time or opening the aperture. When shooting handheld, you may need built-in image stabilization, which allows you to get sharp shots at slower shutter speeds. Above all, the lens you use will have the biggest impact. A lens with a wider maximum aperture can let in more light and allow you to shoot in darker conditions at faster shutter speeds.
