Imaging lens and imaging apparatus

摘要

An imaging lens includes: a first lens having positive refractive power; a second lens having positive refractive power; a third lens having negative refractive power; a fourth lens having positive refractive power; a fifth lens having positive refractive power; and a sixth lens having negative refractive power in vicinity of an optical axis and having positive refractive power in a peripheral portion. The first to sixth lenses are arranged in order from object plane.
