Cameras and Lenses

A camera is a device for taking photographs or shooting films.

In any camera there is a light-tight chamber which protects the photosensitive material from unauthorized exposure light in the process of shooting; photosensitive material (photographic plate, photographic film) or electro-optical sensor with associated equipment; shutter (his role is to execute the lens cover, in the simplest digital camera shutter as a separate device may be absent, his functions are performed by electronics) and lens with image projection. The lens is one of the main parts of the camera.

Camera lenses are made in a wide range of focal lengths. They range from extreme wide angle, and standard, medium telephoto. Each lens is best suited to a certain type of photography. The extreme wide angle may be preferred for architecture because it has the capacity to capture a wide view of a building. The normal lens, because it often has a wide aperture, is often used for street and documentary photography. The telephoto lens is useful for sports and wildlife but it is more susceptible to camera shake.

Now almost everuone has a camera. It is the best way to save your memories for a long time. Just take a photo with a good camera and good lens and your moment will be with your for the whole life.
