Next, control by the MCU 101 during moving image recording will be described according to the control flowchart shown in FIG.
First, it is determined whether or not the LV button 92 is in a pressed state (ON) (step 1). In the following description and FIG. 5, “step” is also abbreviated as “S”.
If it is determined in step 1 that the LV button 92 is ON, the live view is started. That is, the through image is displayed on the back liquid product monitor 35 (S2). The live view is a premise for moving image recording.

Next, it is determined whether or not the external microphone 200 is connected to the external microphone connection terminal 133 (S3).
If it is determined in step 3 that the external microphone 200 is connected to the external connection microphone terminal 133, it is then determined whether or not the center button 93M of the multi-selector 93 is in a pressed state (ON) (S4). .
If it is determined in step 4 that the central button 93M of the multi-selector 93 is ON, moving image recording and audio recording from the external microphone 200 are started (S5).
On the other hand, if it is determined in step 3 that the external microphone 200 is not connected to the external connected microphone terminal 133, a flag for prohibiting contrast AF is set and contrast AF in the subsequent steps is prohibited (S6).

Next, it is determined whether or not the AF button 91 is in the pressed state (ON) (S7).
If it is determined in step 7 that the AF button 91 is ON, contrast detection AF is performed (S8). In the following description, the AF control by this contrast detection method is referred to as contrast AF.
On the other hand, if it is determined in step 7 that the AF button 91 is not ON, the determination in S7 is repeated.

Next, it is determined whether or not the subject is in focus (S9). If it is determined in step 9 that the subject is in focus, the flowchart is temporarily stopped. However, if the subject is a moving object, the focused state is always determined.
If it is determined in step 9 that the subject is not in focus, the contrast AF in step 8 is continued.

  According to the embodiment described above, the AF operation (contrast AF) is performed only when recording is performed from the external microphone 200 connected to the external microphone connection terminal 133 of the camera body 100a during moving image recording. Thereby, it is possible to prevent unnecessary AF operation sound from being recorded during moving image recording. That is, since the built-in microphone 131 is built in the camera body 100a, it is easy to record AF operation sound, and vibrations during AF operation transmitted through the constituent members of the camera body 100a are also recorded as sound. there is a possibility. On the other hand, when the external microphone 200 is used, the arrangement position can be set at a position separated from the AF drive device, and the sound is recorded in a state in which the operation sound or vibration of the AF drive device is not input. can do.

Next, referring to the type of the photographing lens 10, it is determined whether or not the lens driving unit 14 of the photographing lens 10 is, for example, an ultrasonic motor (S13). This is because, for example, an ultrasonic motor has a lower operating sound than a DC motor, and even if sound is acquired by the built-in microphone 131, there is little influence.
In step 13, when the taking lens 10 is an ultrasonic motor drive type, it is determined whether or not the center button 93M of the multi-selector 93 is in a pressed state (ON) (S14).
If it is determined in step 14 that the center button 93M of the multi-selector 93 is ON, moving image recording and audio recording are started (S15). The audio recording does not matter whether the input is the built-in microphone 131 or the external microphone 200.

On the other hand, if it is determined in step 13 that the photographic lens 10 is not of the ultrasonic motor drive type, it is next determined whether or not the external microphone 200 is connected to the external connection microphone terminal 133 (S16). ).
If it is determined in step 16 that the external microphone 200 is connected to the external connecting microphone terminal 133, the pressing determination of the center button 93 </ b> M of the multi-selector 93 in step 14 is started.
If it is determined in step 16 that the external microphone 200 is not connected to the external connection microphone terminal 133, a flag for prohibiting contrast AF is set, and contrast AF in the subsequent steps is prohibited (S17).

Next, it is determined whether or not the AF button 91 is in a pressed state (ON) (S18).
If it is determined in step 18 that the AF button 91 is ON, contrast AF is performed (S19).
On the other hand, if it is determined in step 18 that the AF button 91 is not ON, the determination in step 18 is repeated.

Next, it is determined whether or not the subject is in focus (S20). If it is determined in step 20 that the subject is in focus, the flowchart temporarily stops. However, if the subject is a moving object, the focus state is always determined.
If it is determined in step 20 that the subject is not in focus, the contrast AF in step 19 is continued.
Then, it is detected whether or not the menu button 94 is pressed (ON) (S21). If it is determined to be ON, the moving image recording is stopped.

  According to the configuration of the second embodiment described above, the AF operation is performed during moving image recording when the photographing lens 10 is an ultrasonic motor drive type, and when the photographing lens 10 is not an ultrasonic motor drive type. AF control (contrast AF) is performed only when recording is performed from the external microphone 200 connected to the external microphone connection terminal 133 of the camera body 100a. Thereby, it is possible to prevent unnecessary AF operation sound from being recorded during moving image recording.
