Abstract
A prism type of lens includes a first reflection lens, at least a first lens group, a second reflection prism, at least a second lens group, a third reflection prism, and at least a third lens group sequentially arranged from an object side to an image side. Light is reflected by the reflection prisms to form a bent light axis. Therefore, the optical axis has three sections for the lens groups to move respectively. The bent light axis has a longer distance that the lens of the present invention may have a great zoom range.
