Nahauslöser

I must confess that I would have promised me something more of it. The part has the size of two postage stamps (and looks a bit different, as in the photo) It does what it should, but can really far away from the camera you do not, moreover, the device should when you press the front of the camera ( infrared receiver) be facing. Too bad that Sony does not use a radio. For this, the manufacturer can not of course, but the practical use I can not rate higher.
