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-2, any
focal length between 35 mm and 135 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.
• 70 mm
With the lens zoomed to 70 mm, subjects appear
two times closer than when the lens is positioned at
35 mm.
• 100 mm or more
When the lens is set to the maximum focal length of
135 mm, magnification is approximately four 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.
