The handle for the A7 / A7R is mandatory if you want to shoot portraits, but also because of the (relatively) small number of images you can shoot per battery. He sits on the super camera, nothing wobbles and he is super processed. All important functions and buttons are again available on the handle (wheel, C1, timer, AF / MF / AEL). Unlike some assertions operate batteries from other manufacturers in the A7 and the handle, I recommend: PSC = 1 (charger and 2 batteries for the price is perfectly fine). The handle also features a dedicated on / off switch, wants to know nice if you just used him only because the auxiliary battery and disables the buttons on the handle. The A7 / A7R shows in the display and the viewfinder separately the charge status of both batteries, it is always used only one until it is empty, then the other. The price is 300 euros relatively high, but at that time I already paid 200 euros for my original Canon battery grip. As you have probably bite the bullet and wait for third-party (and hope that then the water / dust protection is maintained). For me a top product that could be a bit better only priced.
