Abstract
The zoom lens includes, in order from an object side, a focusing part, a variable magnification part, an aperture stop, and an imaging part. The zoom lens is switchable between a first state and a second state by replacing a part of the imaging part that is provided to be replaceable. In response to switching from the first state to the second state, a focal length of the zoom lens changes to a long focal length side while keeping an image formation position constant. The zoom lens satisfies predetermined conditional expressions.
