How Does a Zoom Lens Work?

Old Concept, New Technology:

• Like all other electronics, camera lenses seem to get more and more complicated every year. Yet, aside from the flashy new settings and features, at the foundation of every lens is the same basic technology that has been there since the beginning

Background: How Does a Camera Work?

• Before getting into the technical functions of a lens, it should first be understood how a camera works
• The word "photography" is rooted in Greek and roughly translates to "painting with light." The original concept of a camera was literally a pin-sized hole in a wall that let light into a room. This is referred to as a "camera obscura," a Latin phrase that means "dark chamber."
• Cameras today, no matter how advanced, still use this same basic technology. Light is let in through the lens, which then reflects the light onto a sensor that rests inside of the camera
• The camera's lens merely helps to regulate how much light is let in and how the light is processed before reaching the sensor

Know Your Lens:

• The inner workings of a zoom lens, in a most basic form, consist of different small optical glass lenses that are placed at different lengths from each other
• With most zoom lenses, the zoom function is used by manually turning a ring located on the barrel of the lens. Inside of the camera, this will move a group of the glass pieces either closer to or further away from each other

Focal Length:

• It's not unusual to see some professional photographers lugging around two or three different lenses with them wherever they go. The reason they find it necessary to carry all the extra weight is because different lenses have different focal lengths
• Focal length refers to the distance from the camera's image sensor to the optical glass pieces inside of the lens. This distance is what determines how far a lens can zoom in and out and is placed into three basic categories: wide-angle, normal and telephoto
• A wide angle lens refers to a lens with a short focal length. Lenses of this sort, as the name would imply, have a very short, wide view, sometimes enabling photographers to take pictures of an entire room of people with one shot. Lenses in this category are what "fish-eye" photos are taken with
• Lenses that fall under the "normal" category see at focal ranges ranges similar to that of the human eye; 50mm and 35mm lenses would be considered normal focal length lenses
• Last but not least would be telephoto lenses. These lenses are normally the longest (and heaviest) of all categories. When looking through a telephoto lens, the subject often appears very close, yet the view of the subject will be very narrow

In Surveillance Cameras:

• Variable focus in a single lens came to security cameras in the 21st century, but is usually set manually: When you set up your surveillance system, you can choose where in its field of view you want each camera to focus. The camera doesn't zoom in on suspicious activity, and you can't refocus recorded video to read a license plate

Caution:

• Please read the instructions before using the camera
• Please do not open the camera
• Can be used outdoors without a protective cover case
• The use of cameras pay attention to environmental requirements. Not to work at too high or too low temperatures
• According to the sun, avoid the camera to direct sunlight, otherwise damage the CCD
• Thunder or lightning at the time, please use the camera when combined with anti-family devices, to avoid damage to the camera
• Power line and video lines not to long, otherwise the picture will affect the satisfaction, voltage and video signal amplitude is not sufficient
• I would be grateful if the camera on a stable camera tripod in order to prevent falling
• The camera must be firmly installed in order to avoid harm to people and goods
• Be sure not to put the video camera installed on the radiator or heater (or nearby)
