EFFECTS OF ZOOM AND ITS ADVANTAGES

In a zoom lens, the focal length is changed by

moving part of the lens. In the case of the IS-3DLX,

any focal length between 35 mm and 180 mm can

be selected.

35 mm wide-angle

Because the angle of view is wide and the depth of

field is large, sharp photographs with enhanced

perspective and contrast can be taken. 100 mm

With the lens zoomed to 100 mm, subjects appear

three times closer than when the lens is positioned

at 35 mm.

More than 100 mm

When the lens is set to the maximum focal length of 180 mm, magnification is approximately five times

greater than at 35 mm, for genuine telephoto

photography. As the telephoto power is increased, the perspective narrows and the depth of field

becomes more shallow. The result is that objects in front of and behind your subject are more likely to

be out of focus. This can be used to interesting

effect on snapshots and portraits.

Maximum telephoto lengths are particularly useful for taking pictures at sporting events and for nature

photography, when you want to get closer to your subject without disturbing it.
