There are two possibilities;
The focus - a motor moves the lens elements in conjunction with a sensor to get a sharp image.
The zoom - operating the zoom controls, moves an optical group which gives the photographer the desired angle of view.

How a camera produces images?
Light reflects off of all objects that you see around you. The light enters the camera through a lens that focuses the light onto the sensitive plate (film, or sensors in a digital camera). The plate captures the image and it is processed either chemically, if an analog camera is used, or by downloading to a computer or other digital image processor.
How do you block your neighbor from using hardwired video camera surveillance on your yard?
Please need help. Neighbor with video camera on his roof pointing at our front door. How do we disable it or block it? Nicely ask your neighboor to move the camera if possible. If this will not work, easy ways are to point a laser pointer at the camera to temporally blind the cameras image sensor. Hit the camera lens with black spray paint (if you can get to it) or in a worst case shoot out the lens with a BB gun.
How do satellites make images?
Do you have a digital camera ? The digital camera takes a picture when you push the button, then translates a description of the image into a load of digital data, which is stored in the camera until you decide to move it somewhere. Then you can dump the data to a laptop, put it on a CD or DVD, e-mail it to your mother, or send it through a data-cable to a printer. The satellite simply has a digital camera on board. It takes a picture whenever ground controllers tell it to, or when its on-board computer decides it's time for a snap. The digital camera translates a description of the image into a load of digital data, which is stored in the satellite until the ground controllers decide to move it somewhere. Then the data is radio-transmitted to earth, where the controllers can store it in a laptop, put it on a CD or DVD, e-mail it to their mother, send it through a data-cable to a printer, or send it via the web to the local TV station for the 11:00 news.
What VR stand for camera lens?
"VR" is a Nikon thing. It means "vibration reduction." It's got two parts to it. In the camera body, there are two angular velocity sensors. One of them detects up-and-down shaking, the other detects side-to-side shaking. In the lens there is one glass element that's got two motors attached to it. They move the element to compensate for your shaking. The result is you can shoot at shutter speeds far slower than you could without it. The VR lens only works as part of a system, so if you buy a VR lens and put it on a non-VR camera it won't do you any good.
Is 3.6 zoom good for a digital camera?
3.6 is good for general photography. In small digital cameras, the zoom is most useful for framing shots without having to move nearer or farther away, or for getting more or less subject matter in the shot. For true telephotography, you would want a camera with 10x or more.
What is a digital camera lens adapter?
It is a lens that mounts on the end of your camera lens. Some are wide angle adaptors (0.75x is an example) and some are multipliers (1.5x or 2x) which move you half the distance to the subject you are shooting. They can be handy adaptors, but can also reduce critical focus in your pictures, or degrade sharp focus. There are also lens adaptors for digital SLR cameras to use lenses from another type of camera. A lens adaptor could also screw onto the end of a lens to allow filters of another size to be mounted in front of the lens. ---- Just an added note: Although the principle is the same, not all adapters mount on the end of the camera lens. Some adapters mount to threads on the body which may be hidden by a removable ring. So the camera may not always appear to have threads when it does, if you know where to look. Check the manual.

Cleaning Tips for the Canon SLR Camera?
These tips will help you clean your Canon SLR Camera. Canon recommends that you avoid the use of chemicals and water to clean your camera. Power your camera off. Use a lens blower brush to gently remove dust from the camera lens. Wipe your view finder, LCD monitor and lens with a microfiber or soft lens cloth. Move the cloth in a light, circular pattern to remove dust and smudges.
How is a picture taken digitally?
There are 3 steps to creating a digital picture: (1)Focus light (2)Capture image (3)Generate digital file The lens in a digital camera is used to focus the light into a sharp image. Many digital cameras are "fixed focus" meaning that the lens assembly does not move when focusing between far and distant objects. Inside every digital camera is an small electronic chip smaller than your thubnail that converts the focused light energy into electrical signals. Millions of separate light sensors are arranged on the electronic chip in a rectangular "array" behind the lens. When you press the shutter button, the millions of light sensors measure the instantaneous level of light striking their small area and send this data to other circuitry in the camera. There these millions of separate values are converted to a computer file format (usually .jpg) and stored in the memory of the camera.
How you calculate the magnification of a telephoto lens?
Step 1 Write down the maximum focal length of the lens for which you want to find the magnification. For instance, a 70-250 mm lens will have a maximum focal length of 250mm. A prime lens will have only one value listed, and this value should be considered the maximum focal length. Step 2 Multiply this value by 1.6 if you are attaching the lens to a digital camera. Most digital cameras have a 1.6x "crop factor", which means that the outside edges of a scene will be cropped because they do not physically fit on the sensor, making the effective focal length 1.6 times greater than it would be on a film camera. For a 250mm lens, the effective focal length would be 400 (250 times 1.6). Step 3 Divide the effective focal length by 100. An easier way to do this is to move the decimal point two spaces to the left. The effective focal length of a 250mm lens on a digital camera is 400mm, so divide 400 by 100 to arrive at four. Step 4 Multiply this value by two to find the magnification of the lens in terms of viewfinder magnification used in binoculars or telescopes. So a 250mm lens would have an 8x magnification (400 divided by 100 multiplied by two) on a digital camera.
What digitial camera is the best for taking pictures of birds, animals and other on the move things?
You need a camera that will give you a shot action burst. Sony Cybershot has this feature. What it does is every time you hit th button it snaps 3 pictures evenly spaced by 0.5 seconds. It makes sure you get the shot! Any digital camera will work to take pictures of "things on the move." The quality of the images depends on the photographer, not the camera.
How is the lens of a camera similar to the lens of the eyes?
By Ayesha Tariq doing Optometry by COAVS Lahore, Pakistan camera lens is like an eye. lens can focus an object from far to near by its accommodative tone. Ciliary muscles contract so zonule of fibers with which lens is attached relaxe and move the anterior curvature forwad hence increase the power of eye as well.vice versa is done while focusing from near to far. same is done by lens in camera by moving it forward or backward so for increasing or decreasing its power.

How would a three-hour time exposure photograph of stars in the northern sky appear if earth is not rotating?
This answer depends on the location of the camera taking the picture. If the camera is on the ground, then the exposure would come out clearer if the camera was not mounted on a system that could automatically move the lens. If the camera was in LEO (Low Earth Orbit) it wouldn't matter if the earth was rotating.
