Abstract
Official abstract text for this publication.
The imaging lens substantially consists of a first lens group, a stop, a positive second lens group which is a focusing group, and a third lens group in this order from the object side. The first lens group substantially consists of a positive first sub lens group composed of a negative meniscus lens, a positive meniscus lens, and a positive lens; and a second sub lens group including a negative lens and a cemented lens, in this order from the object side. The second lens group substantially consists of a positive single lens or a cemented lens. The third lens group substantially consists of a cemented lens, a positive lens, and a negative lens in this order from the object side.
First claim
Opening claim text (preview).
What is claimed is: 1. An imaging lens substantially consisting of three lens groups in which a first lens group which is fixed while focusing, a stop, a second lens group having positive refractive power which moves toward the object side while focusing from an object at infinity to an object at the closest distance, and a third lens group which is fixed while focusing are arranged in this order from the object side; the first lens group substantially consists of a first sub len…
