LENS APPARATUS AND IMAGING APPARATUS DETACHABLE THEREFROM

摘要

An imaging apparatus includes a sensor configured to photoelectrically convert light from an object to output a signal, a selection unit configured to select one of a first exposure control mode and a second exposure control mode having an exposure changing amount per unit time larger than that of the first exposure control mode, and a controller configured to perform control to transmit diaphragm control information generated based on the output signal from the sensor, first information, and second information to a connected lens unit, wherein the first information is about the exposure control mode selected by the selection unit, and the second information is speed information of a diaphragm unit corresponding to the lens unit.

1. A lens unit including a lens, the lens unit comprising:
a diaphragm unit configured to control exposure to adjust an incident light amount; a memory configured to store speed information for driving the diaphragm unit; and a controller configured to output the speed information stored in the memory to an external apparatus, wherein the controller controls the diaphragm unit based on diaphragm control information periodically transmitted from the external apparatus.
