I usually see anywhere from 6x to 12x optical zoom, then most digital cameras also have digital zoom, up to about 20x
canon a560, canon a720, they have 4 x optcial zoom
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.
Nikon, Canon, Sony etc., are all very good and economical too. The differentiator should not be the price, but how it feels in your hand. Can the camera take the types of pictures that you want to take. Also, very few cameras have 8x optical zoom. Digital zoom is not very good as the picture quality will be poos and you will not like the results of digital zooms. Make sure that the camera you buy has 8x optical zoom.
Optical zoom cameras are used to take a shot in which a far-away object appears both prominently and clearly. Essentially you need a decent zoom lens to obtain this ability, and a good camera with a widely-adjustable lens offers this feature.
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.
Optical and digital. With optical zoom, the camera uses lenses to magnify objects. In digital zoom, the camera's built-in software creates a magnified image.
Optical zoom is way better than digital zoom as digital only expands the picture. Optical zoom actually zooms in.
i suggest canon sx100 which has 8mp and 10x optical zoom
Depends what your using it for
The Olympus Stylus has a 3x optical zoom feature.
The Canon S-series have great zoom and can even do digital zoom for distant objects.
canon a560, canon a720, they have 4 x optcial 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.
That depends on the lens you put on the camera.
A : Entry Level
About 9 miles at sea level. ;)
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.
