Zoom lens and image pickup apparatus including the same

An image pickup apparatus comprising:

• a zoom lens including a plurality of lens units, an interval between adjacent lens units of the plurality of lens units being varied during zooming;
• and
• an image pickup element receiving light of an image formed by the zoom lens,
• the plurality of lens units including:
• a first lens unit with a positive refractive power;
• a second lens unit with a negative refractive power;
• a third lens unit with a positive refractive power;
• and
• a rear group consisting of three lens units having a lens unit B and a lens unit FA,
• the first lens unit, the second lens unit, the third lens unit and the rear group being arranged in order from an object side to an image side,
• wherein the first lens unit consists of a negative lens, a positive lens and a positive lens arranged in order from the object side to the image side,
• wherein the second lens unit consists of a negative lens, a negative lens, a positive lens and a negative lens arranged in order from the object side to the image side,
• wherein the third lens unit includes three positive lenses,
• wherein a lens unit arranged closest to the image side in the zoom lens consists of a negative lens and a positive lens arranged in order from the object side to the image side,
• wherein at least a subunit included in the plurality of lens units moves in a direction having a component of a direction perpendicular to an optical axis during an image blurring correction,
• wherein the lens unit FA moves toward the image side during focusing from an infinity to a closest distance, the lens unit FA being arranged adjacent to the lens unit arranged closest to the image side in the zoom lens and having a negative refractive power,
• wherein the lens unit B has a positive refractive power, and consists of a positive lens A, a negative lens B and a positive lens C arranged in order from the object side to the image side, the lens unit B being arranged at the object side of the lens unit FA, and
• wherein the following inequality is satisfied:
• 3.40≤fxyz/fw<4.55
• where fw is a focal length of the zoom lens when focused at infinity at a wide angle end and fxyz is a focal length of the third lens unit.
