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 6):
The zoom lens according to  claim 1 , wherein a conditional expression\n 3.1\u00d710 \u22123 <(\u03b8 p 2\u2212\u03b8 n 2)/(\u03bd n 2\u2212\u03bd p 2)<6.0\u00d710 \u22123 , is satisfied, where \u03bdp 2  and \u03b8p 2  respectively represent the Abbe number and a partial dispersion ratio of a positive lens having the Abbe number smallest of ones of the Abbe number of positive lenses included in the second lens unit, and \u03bdn 2  and \u03b8n 2  respectively represent the Abbe number and a partial dispersion ratio of a negative lens having the Abbe number smallest of ones of the Abbe number of negative lenses included in the second lens unit, the partial dispersion ratio \u03b8 being expressed by an expression\n \u03b8=( Ng\u2212NF )/( NF\u2212NC ), \n where Ng represents a refractive index with respect to a g-line of Fraunhofer lines.
