Good investment for Portrait photographers

The handle is well finished and polished the already excellent handling of the A77 on again. A real must for all the many images in portrait shoots.
Is really good that the grip can hold two batteries. Thus, the endurance of the A77 is really handsome.

There is only one gripe:
I'm missing two buttons on the handle. As would be once the "DISP" button and the "ISO" button.
It would be even more stunning if you could have access to these two keys in portrait mode.
So I subtract a star.
