Abstract
The imaging lens consists of, in order from the object side, a first lens group Ghaving a positive power, a diaphragm, a second lens group Ghaving a positive power, and a third lens group G. Each of the lens groups includes three or more lenses. A positive lens is disposed on a most object side in the first lens group G, and a meniscus lens, which is concave toward the object side, is disposed to be closest to the object side in the second lens group G. During focusing from an infinite distance object to a close-range object, elements ranging from the first lens group Gto the second lens group Gintegrally move toward the object side, and the third lens group Gremains stationary. The imaging lens satisfies a conditional expression about a radius of curvature of an air lens of the first lens group G
