At the flash output even there is nothing wrong - the images are illuminated uniformly and with the correct brightness. What the quality impression I have from HVLF43AM but greatly reduces, is the fact that he is not attached properly after snapping in the hot shoe of my new Alpha 77, but a few mm play forward and backward. Why here is no locking screw is used, as I was used to before switching to Sony from my Nikon system mean? In the absence of my acquaintance alternatives I will keep the flash well, but fear that it, if it should loosen further, quite well to contact problems of the electrical connections by which the camera could come. Am I given the other positive reviews here with this problem alone? Would appreciate comments in this regard, especially would like to know if anyone has tried to fix it by Sony repair service.
Supplement: I had now to fix flashes and cameras themselves to the repair service sent (unfortunately without success) and then yet found a way, the problem to some extent. For details in the comments.
