A lens apparatus 200 includes an image-pickup optical system 202, 204, an optical element 210 capable of being inserted into and extracted from the image-pickup optical system, an actuator 212 which moves the optical element so as to be inserted into and extracted from the image-pickup optical system, and a controller 201 which operates the actuator in accordance with an insert/extract command signal which instructs insertion and extraction of the optical element. The controller limits an operation of the actuator in accordance with an input of the insert/extract command signal during recording or broadcasting an image taken by a camera 100 using the lens apparatus.
