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.
