Hello Tuomas, others, I was able to lock the focus using QCameraFocus::ContinuousFocus mode. It didn't work with AutoFocus mode.
Another question related to QCamera: Is there a way to configure the camera/viewfinder so that I'll get portrait (3:4) viewfinder/images instead of landscape (4:3), without changing the application orientation? I.e My application is locked to portrait mode and I would like to have the viewfinder to behave like the application "was" in landscape mode. Somehow to force the camera to change the orientation...
