Question: How does this remote work with the A7r ? There is NO menu item for "Remote". The "Shoot" menu contains nothing, whereas  the Alpha 77 and Alpha 57 do.
Document: Have a Sony Alpha 57 and decided on a lark to buy a wireless remote. It does work, but there are a few things to note: the A57 camera has to be in wireless remote drive mode, so make sure that you have it in the right drive mode. The IR sensor is on the grip, so it will only work out in front of the camera. Additionally, the IR on the remote is not strong enough to cleverly bounce off of any reflective surface.
Amazing!!! I love to shoot HDR bracketing with my Sony a7 and don't want any camera shake. The stupid camera doesn't have a self timer for bracketing so you're bound to get some shake and this little guy works perfectly. No programming necessary. One thing to note the ability to shoot with a remote is disabled by the Sony A7 camera by default you need to dig into the menu system to enable the remote. Amazing product for $10
This is a great little device. it works perfectly with my Sony A7r. I am primarily a landscape photographer, so keep in mind the camera's IR sensor is on the front of the camera so if you are using this device to trigger the camera on a tripod, you need to aim the Remote Control from just slightly in front of the camera on the right side. This is not a problem, you just need to be aware that it will not work from directly behind the camera.
There's not much more to say than it's a simple, slim IR remote with immediate and 2s delay functions.Only owned it for a day or so, but it works perfectly with the a6000, out of the box (after enabling IR remote in the camera's menu, of course).
Rating: 5 of 5  Very quick delivery. Worked just fine on my Sony A6000 after I'd set the remote to &#34;on&#34; on the camera menu. Fires every time, I have yet to try it outdoors at a long range. Definitely worth buying.
I like to shoot landscape, night scenes and HDR.
Just received my remote and it worked easily with my Sony A7. After I turned the remote control on in my menu list of the camera I was able to click away using the remote. I have not tested it at great distance yet, but holding the remote behind the camera I was still able to activate the shutter. Can't give it a five until I give it a full test, but so far so good!
The IR Remote Control works perfectly with my Sony Nex7. It only had to be set within the camera menu, and was ready to use. Shooting is fast and precise just immediately after you press the Remote Control button. It is light and small enough to be carried along with the camera. It very helpful in many photographs situations, as slow speed shoots, self photographs, etc. Also, the relation price/value is perfect. I do recommend this product!
I am quite satisfied with this affordable yet reliable IR remote, and I endorse it for any Sony shooters looking for a nice remote solution.Yes, the camera does have IR!Since Sony's manual does not address IR, these steps are necessary for it to operate. Under Menu select Toolbox (on far right), then select # 3, and finally turn Remote Control to &#34;On.&#34;Works like a charm!I suggest storing with the battery out to prevent it demise.
Just press and go! Easy. I have a Sony alpha 7. Carrying case has a slight smell, but who cares?
Answer: A7/A7R menu, turn "Remote Ctrl option to "On"" (default is off). It works.
