I was due to the large price differences (even the original Sony) very skeptical about buying the offered here "best" cable shutter. But I must say: Fits and works as described in my Alpha 77. The pressure point of the trigger to focus is very clearly felt, only with a little more pressure to overcome this resistance and the camera triggers, precisely so as to the knows the cause of the camera here and just as I expected it too. The piece wins determines any beauty contests, it does not have to as well. The price / performance ratio was right in my opinion fully, so full 5 star and a strong buy recommendation this article.
