With Monitor & Control, Sony introduces a new, free app for users of the FX3/FX30 as well as the FX6. It allows wireless monitoring, exposure adjustment and focus control on the larger screen of a tablet or smartphone, but apparently not always in full-screen view. The exact functionality depends on the camera used; in the future, more camera models should be able to be operated with the app.
Sony Monitor & Control App
If a camera is connected to a smartphone or tablet via app, it can be operated wirelessly and basic functions such as starting/stopping shooting and adjusting settings such as white balance or ISO value can be used. The app provides access to various focus functions, including touch focus and AF sensitivity adjustment. A control bar on the side of the screen provides intuitive control of settings, including manual focus. It can also be pre-set with upper and lower focus limits and zoomed up to 350% for precise focus adjustment.
Furthermore, when shooting with the FX6, the aperture can alternatively be assigned to the control bar to precisely adjust depth of field or exposure on a larger screen.
False Color Anzeige
In conjunction again with the FX3/FX30, various tools are available to assist with exposure. The histogram provides a quick overview of overall brightness, while the waveform helps identify exposure levels in different parts of an image. Both features are updated in real time and can be hidden, resized or moved to suit shooting requirements. A false color overlay can also be optionally switched on.
Furthermore, you have control over picture profile/scene file settings, LUT switching and other functions via the app. In addition, a LUT can be applied to log shots for a preview of the later image result.
The app can be used with newer iPhones and iPads, on Android newer Xperia as well as Pixel and Galaxy devices are verified supported - a detailed list 
can be found here.
Cameras must be at current firmware level: FX6 (version 3.00 or higher), FX3 (version 4.00 or higher), FX30 (version 3.00, just released).
