Zoom lens and imaging apparatus

An image capture apparatus comprising:

• a zoom lens;
• and
• an imaging device for converting an optical image formed by the zoom lens into an electric signal;
• wherein the zoom lens includes, in order from the object side, a first lens group having a negative refractive power, a second lens group having a positive refractive power, and a third lens group having a positive refractive power;
• when a lens positional state changes from a maximum wide angle state to a maximum telephoto state, the second lens group moves on an optical axis toward the object side, and at the same time, the first and the third lens groups also move in an optical axis direction such that a gap between ten first lens group and the second lens group decreases, while gap between the second lens group and the third lens group is increases;
• when a change in subject position occurs, close-range focusing is performed by movement of the third lens group, and image shift is provided by shifting the second lens group in directions approximately perpendicular to the optical axis;
• and
• conditional equations (1) and (2) shown below are satisfied
• 0.8<TLw/TLt<0.95 (1)
• 0.6<|fl|/ft<0.8 (2)
• where TLw is a total lens length in a maximum wide angle state, TLt is a total lens length in a maximum telephoto state, fl is a focal length of the first lens group, and ft is a focal length of an overall lens system in the maximum telephoto state.
