Abstract:
An image capture apparatus includes: a zoom lens arranged in a housing and which includes fixed lens groups, movable lens groups and at least three prisms; and an imager device arranged in the housing. The zoom lens includes: a fixed first lens group including a negative lens group having a first optical axis, a first prism approximately perpendicularly folding an optical axis, and a positive lens group having a second optical axis folded by the first prism; movable lens groups and at least one fixed lens group arranged along the second optical axis to perform a zooming action, an image plane position correcting action and a focusing action; and a second prism arranged on an image side relative to a movable lens group that is a closest to the image side among the plurality of movable lens groups for approximately perpendicularly folding the optical axis.
