Abstract
A lens apparatus includes two different optical systems. Each of the two optical systems includes a front lens unit having negative refractive power, an intermediate lens unit, and a rear lens unit disposed in this order from an object side to an image plane side. Each of the intermediate lens units in the two optical systems includes a first reflecting member for bending an optical path at a position adjacent to the front lens unit, and a second reflecting member for bending the optical path at a position adjacent to the rear lens unit. The following conditional expression is satisfied:0.05<out/in<0.50,
