Zoom lens, optical apparatus and method for manufacturing the zoom lens

A zoom lens, comprising:

• in order from an object, a first lens group having positive refractive power;
• a second lens group having negative refractive power;
• a third lens group having positive refractive power;
• a fourth lens group having negative refractive power;
• and a fifth lens group having positive refractive power, wherein
• upon zooming from a wide-angle end state to a telephoto end state,
• a distance between each of lens groups and a lens group adjacent thereto changes to satisfy the following conditional expression:
• 6.00<|MV4/MV2|<15.00
• where,
• MV4 denotes, upon zooming from the wide-angle end state to the telephoto end state, a moving amount of the fourth lens group with an image surface as a reference;
• and
• MV2 denotes, upon zooming from the wide-angle end state to the telephoto end state, a moving amount of the second lens group with the image surface as a reference.

A method for manufacturing a zoom lens which comprises, in order from an object, a first lens group having positive refractive power;

• a second lens group having negative refractive power;
• a third lens group having positive refractive power;
• a fourth lens group having negative refractive power;
• and the fifth lens group having positive refractive power,
• the method comprising a step of arranging the first to the fifth lens groups within a lens barrel in such a manner that:
• upon zooming from a wide-angle end state to a telephoto end state, a distance between each of lens groups and a lens group adjacent thereto changes to satisfy the following conditional expression:
• 2.90<|MV5/MV2|<11.50
• where,
• MV5 denotes, upon zooming from the wide-angle end state to the telephoto end state, a moving amount of the fifth lens group with an image surface as a reference;
• and
• MV2 denotes, upon zooming from the wide-angle end state to the telephoto end state, a moving amount of the second lens group with the image surface as a reference.
