How do i use my digital zoom on my vivitar dvr 914

Instructions for this are probably contained within the camera manual, but be warned - whereas optical zooms actually magnify the original scene, digital zooms rely on internal software to interpolate pixels to give the impression of magnification, which can lead to disappointing results. It can be better to shoot at the maximum optical zoom, then use software of your computer to enlarge the image in a more controlled fashion - the algorithms in the computer software may also be capable of more subtle results.
Don't forget also that the longer focal length lens you use, the more camera shake will be magnified, so a sturdy support is essential.

Just purchased it from bid tv it has 4xdigital zoom would i have been better to get optical zoom instead this is my first camera

Digital zoom enlarges the ccd image and will become more pixelated the more you zoom and optical zoom uses an actual lens to magnify the image coming into the camera. optical zoom is better than digital zoom.

No 'camera shop' out there will be able to fix your camera, they will all just want to send it to Kodak for a new lens and will want about $150-200 for the job.

I know one place online that can probably help you out. Google: "darntoothysam"

Optical zoom

Hey needacamera,
The range of an optical zoom lens refers to how wide angle to telephoto the lens covers. An example of a 6x optical zoom would be an 18mm-108mm lens, which covers wide angle to telephoto. An example of a 3x zoom lens would be an 18mm-54mm lens, which would provide a capability of capturing images from wide angle to normal views. To calculate the x factor of an optical zoom you would divide the largest number by the smallest number on your zoom. I hope this helps!

Go Ahead. Use Us.

Optical vs. digital zoom

It's important to understand this difference, as you could be disappointed with the results if you use one rather than the other. Optical zoom works like the zoom on a traditional film camera. When you push the button to zoom in or out, physical lens elements move inside the camera, reducing the field of view and making the object you're shooting appear closer. Digital zoom, on the other hand, has no moving parts. The camera interpolates a small portion of an image to artificially restore the file to its original size. Using its electronic brain, the digital camera analyzes what it sees and digitally zooms in, usually two or three times closer. Unfortunately, digital zoom also reduces the resolution of an image, so your picture will tend to be more pixilated than the same image taken with an optical zoom camera. If you're just snapping an image to e-mail to a friend, this loss of resolution won't be so noticeable. But in situations where the highest quality counts, skip the digital zoom and use your PC's image-editing tools to zero in on your subject.

Differences between Optical Zoom and Digital Zoom

When you change the focal length of a zoom lens, the subject is magnified. Optical zoom replicates the zoom of a 35mm camera. Digital zoom takes a portion of the image's data and displays it at full size, producing a magnification of the original image, similar to the effect of using a telephoto lens. However, the process is different from the magnification produced using the camera's optical zoom, and the stronger the digital zoom, the more the image will degrade.
