Abstract:
A zoom lens including in order from an object side: a positive first unit configured not to move for zooming; a negative second unit configured to move to the image side for zooming to a telephoto end; and a relay lens unit configured not to move for zooming, wherein the first unit consists of five lenses including, in order from the object side, a negative lens, a positive lens, a positive lens, a positive lens and a positive lens, or six lenses including, in order from the object side, a positive lens, a negative lens, a positive lens, a positive lens, a positive lens and a positive lens, and a refractive index of the negative lens in the first unit, an Abbe number of the negative lens, a focal length of the negative lens, and a focal length of the first lens unit are appropriately set.

Claim (Index 8):
An image pickup apparatus comprising:\n a zoom lens comprising in order from an object side to an image side:\n a first lens unit having a positive refractive power and configured not to move for zooming; a second lens unit having a negative refractive power and configured to move to the image side for zooming from a wide angle end to a telephoto end; and a relay lens unit configured not to move for zooming, \n wherein the first lens unit consists of five lenses including, in order from the object side to the image side, a negative lens, a positive lens, a positive lens, a positive lens and a positive lens, or six lenses including, in order from the object side to the image side, a positive lens, a negative lens, a positive lens, a positive lens, a positive lens and a positive lens, and \n conditional expressions\n 39<\u03bd n< 48, \n 2.24< Nn+ 0.01\u00d7\u03bd n< 2.32, \n 1.79< Nn< 1.91, and \n 1.5<| fn/f 1|<2.0 \n \n are satisfied, where Nn represents a refractive index of the negative lens in the first lens unit, \u03bdn represents an Abbe number of the negative lens, fn represents a focal length of the negative lens, and f 1  represents a focal length of the first lens unit, the Abbe number \u03bd being expressed by an expression\n \u03bd=( Nd\u2212 1)/( NF\u2212NC ) \n where NF, Nd and NC represent refractive indices with respect to an F-line, a d-line and a C-line of Fraunhofer lines, respectively, and an image pickup element configured to receive an image formed by the zoom lens.
