If you create a Corona Camera in a view other than top (e.g. front, left), it is created in a different way than the native physical or target cameras. If you hold mouse button and drag in the viewport, the target will move towards/away instead of being just projected flat onto the grid.
I may be a feature, but I am not sure about the benefits of it, and I also think it is expected to behave the same way as the standard cameras.
