The larger your camera's sensor, the larger the photosites, the more resultant megapixels, which allow for a better image and a higher resolution. ... Low-light performance: A large sensor contains larger photosites, which enhance the camera's ability to capture low-light photos in comparison to a small sensor.

Is a bigger camera sensor better?

A sensor with bigger pixels will collect more light, and more light will generally improve image quality. ... This is more related to pixel size than sensor size, although having larger pixels generally results in greater usable dynamic range as you go to higher sensitivities.

Does image sensor size matter?

The size of the camera's sensor determines how much of this light is used to create the image. Because a sensor stores such valuable information, if there is a large camera sensor size, more information can fit, producing better quality images than smaller sensors.
