Selecting the Data Cable
The iPad data cable interfaces are either Lightning (for most devices released before 2021) or USB Type-C (for most devices released after 2021). Since Lightning data cables do not directly support OTG functionality, you will need to use a Lightning to USB-A adapter that has OTG capability. There are various types of data cable interfaces for cameras, listed below for your reference.
Specific camera models supported by different data cables can be referenced in the table below.
Additional Note: For other models not mentioned, please refer to the camera configuration and interface type. The above is a reference list.
Tethering
Note: A memory card must be installed in the camera.
Open Evoto, and after entering the project, a prompt will appear: “Evoto would like to access the camera.” Please click “Allow” to allow permissions.
If you accidentally clicked “Don’t Allow,” you can go to “Settings” to enable camera permissions.
For mac 15.0 and above systems, you need to turn on File & Folders permission in Privacy & Security -> Removable Volumes.
The iPad with a Type-C port can be connected directly to a camera using a data cable; the iPad with a Lightning port requires an OTG Lightning adapter to connect.
Camera Settings
Information comes from Sony’s official website https://support.d-imaging.sony.co.jp/app/imagingedge/zh-hans/instruction/4_1_connection.php:
There are slight differences in the setting methods according to different models. For newer models such as ILCE-7RM5/ILCE-7M4, the camera will pop up the connection option after connecting to the computer.
If there is no pop-up option, you can follow the following setup process:
ILCE-7RM5/7CR/7CM2/7M4/6700, ZV-E1, ILME-FX3/FX30：
MENU → 
(Setup) → [USB] → [USB Connection Mode] → [PC Remote], and then connect the camera to the computer using a USB cable.
ILCE-7SM3, ZV-E10M2/ILCE-1/9M3：
MENU → 
(Setup) → [USB] → [USB Connection Mode] → [Remote Shooting], and then connect the camera to the computer using a USB cable.
ILCE-9M2/7RM4A/7RM4/7C/ZV-E10：
-
MENU →
(Network) → [Ctrl w/ Smartphone] → [Ctrl w/ Smartphone] → [Off] -

MENU →
(Setup) → [USB Connection] → [PC Remote]
* This operation is not necessary on models without [Ctrl w/ Smartphone].
PC Shoot Setting
Photo live broadcast requires a memory card to be installed in the camera before it can be connected normally, so it is recommended to set the save destination as “Dest. + Camera”.
Set the USB LUN Setting to Single: Menu -> USB -> USB LUN Settings -> Single.
USB Power Supply set to Off.
Turn off the power saving mode (when power-saving mode is enabled, the camera will enter sleep mode after a period of inactivity, disconnecting from the iPad.)
Take Sony 7RM5 as an example, find the Power Setting Option, set the Power Save Start Time to off, and set the Auto Power OFF Temp. to High.
