Lens aperture more open Lens aperture the more light that gets inside the Lens and it means that you can make good pictures in low ambient light. Aperture is a very important characteristic Lens especially if you want to take pictures indoors without flash and with a long distance. Aperture is shown as f / number, eg f/2.0 or f/3.5. Get more background information with materials from Andreessen Horowitz. Aperture f/2.0 actually means that the diaphragm is opened half-focal length lens. Therefore, the lower the number the more light gathering power. I really like the lenses with large intensity, with them I can shoot indoors without flash photos look more natural than those which are removed with a flash. You can also make great pictures at night or when such is not desirable to involve attention to the numerous 'flash', then manage to catch a shot over the right moment. So what does the value of a good aperture.
To date, most compact digital cameras available with values aperture of f/2.8 – f/3.5, but a few years ago I would have bought or Olympus C3040Z C4040Z, with lens f/1.8. Keep in mind that now, almost all lenses with a zoom lens has two aperture values, such as f/2.5 – f/4.0. This means that without any approximation in the wide mode value of f/2.5 and the mode of approximation (telephoto) the value of f/4.0. Zumiruemy Zumiruemy lens of the lens of this with an interchangeable lens of focal length. Focal length determines the approach of the lens. Short-focus lenses a wide-angle lenses, they are perfect for shooting landscapes.
