At first I had my problems with regard to the installation of the camera, but after 100 test photos I always come along better and climb into the fantastic possibilities of the small "light giants" From Aperture 2.8, a continuous focus is ekennbar. 1.8 is really only good if you want to make detailed pictures. The autofocus is sometimes too hasty, he sometimes makes an already sharply focussed image again blurred. But with a little patience you get there too the low rotational.
