Abstract
Official abstract text for this publication.
Disclosed is an imaging lens substantially consisting of a first lens group having a positive refractive power and a second lens group having a positive refractive power, arranged in this order from the object side. Focusing is performed by moving the entire second lens group along the optical axis. The most-image-side lens of the first lens group, a lens which is second from a most-image side in the first lens group, and a lens which is third from the most-image side in the first lens group are all meniscus lenses with convex surfaces toward the image side. The imaging lens satisfies the formula: 1.0<FA/FB<8.0, where FA is the focal length of the first lens group, and FB is the focal length of the second lens group.
First claim
Opening claim text (preview).
What is claimed is: 1. An imaging lens substantially consisting of a first lens group having a positive refractive power and a second lens group having a positive refractive power in this order from an object side, wherein focusing is performed by moving an entirety of the second lens group along an optical axis; and a most-image-side lens of the first lens group, a lens which is second from a most-image side in the first lens group, and a lens which is third from the most-image…
