Can thus trigger with my Nex 7 the flashes Canon 420 EX and Metz 45 CT 5. With another adapter (Seagull) I had previously, which unfortunately did not work with the Metz flash. In this respect, I am very satisfied. The Metz flash has indeed its own amount of light control (automatic apertures), as it used to be common, so far as one does not need the TTL control. TTL does not, of course, but that is in all of these third-party adapters that. The star deduction because the "tail hook" which fixes the adapter to the camera, can not be solved by pressing a button.
