Jurgen,
This is kind of OT from Paul's original thread but here goes anyway:
The viewfinder application can only use the optical image from the iPhone camera with it's native FoV. For wide angle lenses the physical image can only cover a portion of the total view and so if you set up 28mm as a lens with the Alpa then you'll only see an image that covers 80 percent or so of the total view with the remainder displayed with shaded light/grey lines. If you add a 3rd party wide angle lens adapter to the iPhone the you will be expanding the optical FoV & coverage and so now you can zoom the image to see the full view. With a wide angle adapter fitted and the full 28mm lens view selected you will see the longer lens viewfinder masks smaller on screen. You can zoom in if you want have a more detailed view but it's just a display zoom, not an optical zoom.
Does that make sense?
