Sony Alpha 7R doesn't support ARW images transfer through Camera Remote API, allowing to download small JPEG previews instead. Supported features table says ILCE-7R doesn't support that API group. However, there is no such note for ILCE-7R2. Does it mean ILCE-7R2 allows to transfer ARW images through Camera Remote API?
Yes, the ILCE-7RM2 can transfer ARW images using the Camera Remote API. Make sure that you have installed the latest version of the Smart Remote Control application on the camera.
