EFFECTS OF ZOOM AND ITS ADVANTAGESIn a zoom lens, the focal length is changed bymoving part of the lens. In the case of the IS-3DLX,any focal length between 35 mm and 180 mm canbe selected.35 mm wide-angleBecause the angle of view is wide and the depth offield is large, sharp photographs with enhancedperspective and contrast can be taken.100 mmWith the lens zoomed to 100 mm, subjects appearthree times closer than when the lens is positionedat 35 mm.More than 100 mmWhen the lens is set to the maximum focal length of180 mm, magnification is approximately five timesgreater than at 35 mm, for genuine telephotophotography. As the telephoto power is increased,the perspective narrows and the depth of fieldbecomes more shallow. The result is that objects infront of and behind your subject are more likely tobe out of focus. This can be used to interestingeffect on snapshots and portraits.Maximum telephoto lengths are particularly usefulfor taking pictures at sporting events and for naturephotography, when you want to get closer to yoursubject without disturbing it.IS/L LENS B-28 H.Q.
