So I bought the shutter release maybe 18 months ago or so. The battery was supposed to be good for 30 hours and I only got 2.5 out of it. I emailed the company to see if they would send me a new one and they basically said no way. I kept the battery out of the release except when I was using it. So it wasn't that. Well lucky for me I didn't like the digital part of it and I could still use it as a manual release. But last night, using it for the first time in about 9 months due to other things going on, it didn't work at all. When I held the button it would open the shutter, when I let go it would close. But I couldn't get it to lock open. When I did it it would open, then as soon as it was locked it would close. Then when I went to press it to unlock it it opened then closed when I released it. Is there a problem with it, with the camera? Or am I missing something as simple as a setting on the camera with AF or something? Now when I use bulb in the dark I have it on MF not any of the AF modes. So I don't think that could be it? But maybe I'm wrong? When I press it it's not trying to focus or anything like that. When I used it the last time I can't remember if the button came up slightly when I locked it. Or pressed in when I went to release. In my feeble memory I don't think it did. I'm so hoping this is just this crappy release and not my camera! Any ideas?
