ofcourse optical zoom..................
Zoom in is used to get a closer look and narrow your view. zoom out is for making your picture have a wider view.
Digital zoom uses software to zoom in further than regular optical zoom, which uses lenses to magnify the picture.
every thing hi
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.
A zoom lens can change its focal length, allowing you to zoom in and out on a subject. A telephoto lens has a fixed focal length and provides a magnified view of distant subjects.
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.
A zoom lens you can go from one focal length to another such as 70-200mm and a fixed is one focal length such as 50mm
You cannot change it on mobiles or ipods. But you can zoom in on laptop.or something big like desktop by setting and go zoom button and put it to 15X zoom :)
A telephoto lens has a fixed focal length, providing a specific level of magnification, while a zoom lens can adjust its focal length to vary the level of magnification.
the nike zoom vapor carbon fly is the updated version of the nike vapor jet 4.2
If you're talking about optical zoom there is no difference other than you will be closer to the viewed object.If you are talking about digital zoom, the size of the pixels will increase and blur.Hope that helps!
