I am seriously considering getting an ILCE-7R, but the information I'm getting from Sony is unclear. *The ability to use the camera remotely will be important to me. *I would be grateful to learn the experiences of existing users: * *- Wifi android apps. *I'm advised by Sony that, contrary to the information on their website, recording video/movie is possible. *But they tell me that this function is limited to start/stop of recording and that the camera's view (during video recording) is not displayed on the smartphone/tablet. *Is this right? *I appreciate that my query seems somewhat argumentative (with Sony) but the information that I'm getting from them is a little contradictory. * - What kind of range, distance (between camera and smartphone/tablet) are users finding that they are getting? * - I also see that a usb-cable windows application is available. *Have users found that, in use, there are any limits on cable length? I would be grateful for the benefit of users' experience.
