Optical zoom uses lenses to focus on objects further away... it is the lenses which do the 'zooming'. Digital zoom is where a photo is taken using the same set of lenses all the time and using software to enlarge the picture.

What is the difference between digital and optical zoom?
Digital zoom uses software to zoom in further than regular optical zoom, which uses lenses to magnify the picture.
What is the difference between Optical Zoom and Digital Zoom for a digital camera?
A optical zoom use the lenses to focus in on a subject, pretty much the same way binoculars work. Digital zoom magnifies the subject by enlarging in in the pic thru a digital process, this is not a true type of zoom.
What is the Difference between optical zoom and dynamic zoom?
ofcourse optical zoom..................
What is better digital zoom or optical zoom?
Optical Zoom is the true zoom, Digital is basically the zoom in of what the highest optical zoom is. Therefore Optical Zoom is the better zoom, and gives a much clearer picture.
What type of digital camera is better either with optical zoom or digital zoom?
Optical zoom is way better than digital zoom as digital only expands the picture. Optical zoom actually zooms in.
What is the difference between digital and optical zoom in a digital camera?
Digital just takes a small clip of the image and enlarges it while optical is just like if you stepped in closer to whatever you are photographing.
How much difference is there between a x50 zoom and x60 zoom on a digital camera?
You will have an image about 20% larger at x60, but there is catch. Usually magnification of that amount is a combination of the optical zoom and digital zoom. The total obtained by multiplying. With digital zoom, the quality will likely decrease faster as the magnification increases. So normally, the optical zoom will go to maximum before the digital zoom begins to operate. So if the x50 has 10x optical and then 5x digital, it could produce a better image than 6x optical with 10x digital zoom (unless the optics are not that great). It's good to know which is which. See if you can find reviews on both.
Zoom on Cannon Poweshot?
The Cannon Powershot has both and optical and digital zoom features. Optical zoom is far superior to digital zoom.
What are the advantages of using optical zoom?
If you use an optical zoom, you can take pictures without getting really close to things. An optical zoom is better than a digital zoom, because an optical zoom does not cause pictures to be pixely or grainy, and digital zooms often do.
What is the average optical zoom for a camera?
I usually see anywhere from 6x to 12x optical zoom, then most digital cameras also have digital zoom, up to about 20x
Why is a digital zoom worse than an optical zoom?
The reason an optical zoom is better to have than a digital zoom boils down to quality. When one uses an optical zoom the subject is brought in closer without losing quality. When a digital zoom is used, the camera crops and digitally enlarges the picture, sacrificing quality.
Is 3x optical zoom and 5x digital zoom good?
3x optical zoom and 5x digital zoom are standard features on most mid-range pocket digital cameras. A better optical zoom capability would be 6x or 8x optical. The digital zoom capability can be ignored, since all it does is crop and expand your image, necessarily reducing its resolution. Digital zoom may be handy for giving you a close-up view in the viewfinder or on the viewscreen, but the photographer must remember that picture quality shot with digital zoom may be compromised. POOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOP U:P
