Sorry. I should have been more explicit. I want to set up my camera on a tripod pointing at birds on my feeder and trigger the shutter from behind the camera. The Sony and similar remotes won't work because the remote sensor is on the front of the camera.
You were explicit enough Warren with what you were looking for information on - it's just unfortunate that the a330 doesn't accept a 'wired' remote because there is nowhere to plug a wired one in it... but only works with the wireless remote. The link to the video on YouTube was 'on the off chance' that it would give you some idea if the remote the presenter was using would have helped you do what you wanted...
watched it and I don't believe it would help you - even though it does show the camera shutter being operated from behind
the camera instead of 'in line of sight'. His 'spiel' does say it will operate 15 to 30 feet away
from the camera... hence why I wondered if it would help you achieve what you wanted to do - - - even if it meant placing the camera by the feeders etc., and 'in line of sight' OR 'at an angle' to allow you to operate it. You know the area you have to work with/in while we can only make some 'possible' suggestions to help you work round your situation.
If you are not able to change your set up for camera placement and 'your' position (in some hide maybe?) then the only option left to you is to change the camera to one that accepts a wired remote controller - as has been suggested by others. Whatever you decide to try and do I'm sure we all wish you well with overcoming the issue.
All the other Sony cameras I've had (and listed in my first response) have been and are a pain in the butt for operating with the wireless remote. They work the same as on your a330 - in front of the body. The only difference is that they all will take a wired controller as well as work with the wireless remote BUT the a7rii uses a different wired remote and not the old Minolta (which I have a ginormous long one of) as well as a couple of short ones. So I'll have to go get one for the a7rii. Yet another annoying thing about Sony.
