1. A modular lens system for use with a camera comprising:
a front section including one or more lenses;
a central section configured to be coupled to the front section and including one or more lenses, the central section comprising a microcontroller and a user input element operatively connected with the microcontroller; and
one or more motors configured to move the one or more lenses of the front or central section to effect a change in an optical property;
wherein the one or more motors are configured to move the one or more lenses of the front or central sections based on a control signal provided by the microcontroller in response to the microcontroller receiving an input signal from to the user input element, and wherein the microcontroller is configured to not receive any control signal from a camera that the modular lens system may be connected with to operate the modular lens system independent of the camera.
