Question: Will this remote work for the Sony Alpha A100?
Document: This little remote works well with my Sony Alpha NEX-5. The remote has to be in view of the camera sensor to work, but there's a 2 second delay button, so you can push it and hide the remote real quick so it doesn't show in the photo.
So excited about this wireless remote for my Sony alpha, but It doesn't work. No Blinking light, no camera response when It is on remote mode.The Battery works, 3.2v measured but trying changing the battery's position but It never worked. Really dissapointed :(
When I received it, I could not work with it until I read Amazon's reviews that help me because the manual inside the box is useful.In a Sony Alpha a57, you should go to the &#34;shooting options&#34; and select remote o wireless (the others options there are 10 seconds shooting, 2 seconds shooting or single shooting)
This worked perfectly with my Sony Alpha A55 SLT camera. To get it to work on an A55, first remove the plastic strip from the remote control (used to cover battery contacts.) Then, turn on the A55, press the left directional button on the control button/pad (drive mode- has timer and continuous shooting icons).
Shipped quick. It works awesome. You dont have to point the control directly at the camera. You can point the remote in the direction where the sensor on the camera is located (on the right of my sony alpha a390)& it will still work. For example, if the camera is facing me, I can point the remote to my left and it will work.However, if I point it behind me or to my right it will not work. Overall,works good!
Hi,Recently I purchased this remote but not able to use it. I have a sony alpha 230 DSLR. I'm not able to configure the remote to work with my camera. The instructions I got from the remote package didn't help either.I'm rating LOW because proper instructions are not given.Once I find the remote working, I will re-rate this product.
I had a hard time deciding between this Opteka RC3 remote and the more expensiveSony Alpha RMT-DSLR1 Camera Remote (Black). However, I have found that only two buttons of the Sony remote work for taking pictures, and they are the two small buttons too close to each other on the top left; interestingly, all the other buttons on the Sony are only for playback functionalities. For taking pictures, this Opteka is identical to the tripled price Sony brand, and it was a no-brainer for me.
I got the remote and instructions were a bit fuzzy. On my Sony Alpha A57 the Drive mode must be set to remote Cdr. Once I figured that out (Read the book) it works fine...duh!With my camera this remote seems to work either from the front of my camera or behind at closer range. Once I got the correct remote cdr setting, it works very well. Nice little application for tripod work if you are alone.
useless - does nor work with my Sony Alpha A65 - no reaction( disappointed totally, wasted money, will send back
I was very skeptical that this little wireless controller would work. I does work with my Sony Alpha 390. Like many other reviews, the instructions are worthless. It took a couple of minutes to figure out how to use it on bulb setting but I finally figured it out. It is a cheap item but for the price I believe I will get what I paid out of it.
Answer: No, I have the A100 as well and that one requires a remote with a wire. It doesn't have a wireless option.
