I am not concerned about getting mis-focused photos but with the fact that the slight fuzziness and easy shifting superimposed image makes fine focusing very difficult regardless of the results. If the superimposed image was as sharp and stable as my 0.72 camera, I would not have a problem even with the smaller image size.
