Photographing lens, optical apparatus and method for manufacturing the photographing lens

A method for manufacturing a photographing lens comprising the steps of:

• configuring a first lens group that has positive refractive power and includes, in order from an object, a front lens group and a rear lens grow having a longest air interval from the front lens group in the first lens group;
• configuring a second lens group that has negative refractive power and includes, in order from the object, a negative lens and a cemented lens in which a positive lens and a negative lens are cemented in order from the object;
• and
• arranging the first lens group, the second lens group and a third lens group having positive refractive power, in order from the object,
• the second lens group moving along an optical axis upon focusing from an object at infinity to an object at a finite distance, and
• the following conditional expressions being satisfied:
• (−f1an)/f1>1.35
• ν1bp−ν1bn<32.0
• Rm/f2>0.78
• ν2n−ν2p<30.0
• where f1 denotes a focal length of the first lens group, f2 denotes a focal length of the second lens group, f1an denotes a focal length of a negative lens of which focal length is shortest in the front lens group, ν1bp denotes an Abbe number of a positive lens of which Abbe number is largest in the rear lens group, ν1bn denotes an Abbe number of a negative lens of which Abbe number is smallest in the rear lens group, Rm denotes a radius of curvature of a cemented surface of the cemented lens of the second lens group, ν2p denotes an Abbe number of a positive lens of which Abbe number is smallest in the second lens group, and ν2n denotes an Abbe number of a negative lens of which Abbe number is largest in the second lens group.
