Examiner has withdrawn the rejection of claims 12 and 13.

The invention relates to a zoom lens system having five
groups of lenses which function to prevent image shake. On
page 7 of the specification, Appellant discloses that in zoom
lenses having five groups, the displacement means 1 shown in
Figure 1 for effecting vibration reduction is provided in the
second lens unit.
Independent claim 1 is reproduced as follows:
1. A zoom lens system with vibration reduction function
including, in succession from an object side:
a first lens unit having positive refractive power;
a second lens unit movable along a direction across an
optical axis thereof and having negative refractive power;
a third lens unit;
a fourth lens unit having positive refractive power;
a fifth lens unit having negative refractive power;
