Maximum Focal Length: 50 millimeters (The maximum distance between the lens and the image sensor that allows the subject to be in focus. The greater the focal length, the smaller the area of scene captured.)
Maximum Aperture: f/2.8 (The limit to how wide a lens can be open, typically expressed in f-numbers. The smaller the number, the larger the aperture and the more light that can enter the lens.
