摘要： The present invention provides a method and system for acquiring operating parameters of a photographic lens, including: a control circuit and a storage unit that are configured in the photographic lens, where the control circuit acquires an operating parameter of the photographic lens by using a focusing ring position sensor, a zoom ring position sensor, an aperture ring position sensor, an accelerometer and a gyro sensor; and the control circuit is further connected to a camera or an external data reading device by using a communication interface, to output the operating parameter after data encapsulation in real time.
