IMAGING LENS AND IMAGING APPARATUS
Document Type and Number:
Japanese Patent JP2016099552
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compact imaging lens which has satisfactorily corrected various aberrations and an imaging apparatus including the imaging lens.SOLUTION: The imaging lens comprises, in oder from an object side, a positive first lens group G1, a diaphragm St, a positive second lens group G2, and a negative third lens group G3. The first lens group G1 comprises, in order from the object side, one or more positive single lenses, one or more groups of cemented lenses, one or more negative single lenses, and a negative meniscus single lens which is concave on an image side. The second lens group G2 comprises, in order from the object side, a cemented lens in which a negative lens and a biconvex lens are cemented in this order from the object side, and a biconvex lens. The third lens group G3 comprises, in order from the object side, a negative meniscus lens which is concave on the image side, one or more negative lenses, and one or more positive lenses. The third lens group G3 is fixed to an image surface Sim.
