worked very well, better than the standard lens (18 - 55mm) and also better than the Tamron lenses. Very high light intensity (not the standard wording 1: 3.5 - 6.3 fooled), so that great shot in a dimly lit room to 12,800 ISO without noise (max A4.) Perfectly succeed. In the macro range however, you should use the standard lens or manual focus with minimal zoom. (Sony A57)
