Compact cameras are small digital cameras with fixed optics that cannot be replaced. They are comparatively small next to a system camera and are easier to take on the go. Select how long the optical zoom camera should be, the resolution of the sensor and the sensor size. Higher resolution means greater detail and the larger the sensor, the less noise you get in the images. Practical is if the camera has built-in stabilization for less shake sharpness, flash to lighten the shadows and video recording in 4K for the best possible recording quality.
