Question: Does this mount on a tripod in the portrait position?
Document: I have never owned a camera without the optional grip. In the old days they were called autowinders. I love the Sony grips as they give the camera some heft resulting in stability. When holding the camera in the portrait position, you have the important buttons in the correct position of the grip in order to make adjustments while you are shooting. And, of course, having the extra battery takes the worry out of running out of juice.
This Sony made vertical grip for the A77 is very well designed. All the controls are well placed for using the camera in the vertical position and having easy access to all the standard controls. Really looks impressive too.
high-quality-the buttons are responses and it makes it feel like a high tech device-it works well with my tripod and quick speed shoulder strap
This is a nice, solid grip. It's a little expensive for a grip but worth the features.Pros:Lets you have 2 batteries instead of 1.Easy to install and remove.Buttons are in the same position as the camera body.Grip feels as good in the hand for shooting.Doesn't add much weight to the camera.Cons:Have to turn on/off the buttons with a power switch.Can drain the batteries if you leave the buttons on.I highly recommend this grip.
I was down to 60%. I put one battery into the charger and it was still at 100% full. Therefore, the other one was being used at least first, if not automatically 2nd. So, do I have to switch the position of the two batteries when the first one is dead? I don't know.I highly recommend the purchase of this battery grip. Amazon had THEE LOWEST PRICE of any retailer on earth. Most places wanted $400.00.
This grip will help you during portrait shot. The comfort will make you keep on shooting the whole day with the help of its second battery.The grip connects in the camera tightly and secured.
Seriously--there's no processor in this--it just holds another battery and echoes the stock buttons, but in portrait mode. No reason it should cost nearly an entry-level DSLR camera. If you've got the money and don't mind the price, it does the job well (just like any other Sony vertical grip).
i rated it only a 4 because you must have a genuine sony battery in bay one. other than that it is perfect. all control knobs available in portrait angle. a must have if you tend to turn your camera portrait angel allot your hand can stay to the right rather than reaching over too hit shutter release.
The grip with it's two battery capacity makes a normally great camera exceptional.Gone are the days of worrying where the batter level is, or cranking your hand around in a weird way to grab &#34;portrait&#34; shots.If you have an Alpha 77 and don't have one of these, you're stupid. Go get one for Pete's sake and quit your whining.
This is a professional-quality grip that doubles your battery life and allows ease of use when holding the camera in portrait orientation. It's a Sony branded product so you'd expect nothing but the best and that is exactly what you get.I especially love the way Sony shows you how much battery life is remaining in each individual battery, and the way the software and hardware drain one battery completely before moving on to the next.
Answer: No.  Landscape only.  So you'll need a ball-head or some other device.  Most long lenses have mounting rings which can go portrait or landscape.
