Variable magnification lens and camera having the same

A variable magnification lens comprising, in order from an object side:

• a first lens unit having a positive refracting power;
• and
• a second lens unit having a negative refracting power,
• a magnification change being performed by a change of a distance between the first lens unit and the second lens unit,
• wherein the first lens unit consists of, in order from the object side:
• a sub-unit (1a) comprising at least one lens element;
• an aperture stop;
• and
• a sub-unit (1b) comprising at least one lens element,
• wherein all lens elements constituting the first lens unit are arranged with intervening air spaces between one another, and
• wherein the variable magnification lens satisfies the following conditions:
• 1.1<FLw/IH<1.35 2.50<FLt/FLw<5.0
• where FLw is a focal length in a wide-angle end position, FLt is a focal length in a telephoto end position, and IH is a maximum image height.

• and
• a second lens unit having a negative refracting power,
• a magnification change being performed by a change of a distance between the first lens unit and the second lens unit,
• wherein the first lens unit consists essentially of:
• a lens element having a negative refracting power;
• and
• two lens elements each having a positive refracting power,
• wherein all the lens elements constituting the first lens unit are arranged with intervening air spaces between one another, and
• wherein the variable magnification lens satisfies the following conditions:
• 1.1<FLw/IH<1.35 2.50<FLt/FLw<5.0 0.2<Fbw/FLw<0.37 0.4<FL1G/FLw<0.7
• where FLw is a focal length in a wide-angle end position, FLt is a focal length in a telephoto end position, IH is a maximum image height, Fbw is a paraxial amount of a back focal distance in the wide-angle end position, and FL1G is a focal length of the first lens unit.
