Abstract:
A super wide angle lens substantially consists of a positive first lens group in which a positive first lens, a negative second lens, a negative third lens, a negative fourth lens, a positive fifth lens, a sixth lens unit that is a cemented lens, a seventh lens, an aperture stop, and an eighth lens unit that is a cemented lens are arranged in this order from an object side, a second lens group in which a first lens unit that is a positive single lens or a cemented lens and a second lens unit that is a cemented lens are arranged in this order from the object side, and a third lens group including a positive lens. The super wide angle lens is structured in such a manner to satisfy conditional formula (1): 0.8
