I love Alpine Labs. I think my Radian is awesome, and I jumped right on the Spark when I was prepping for a trip. And, as a wired or infrared remote, it’s great, although the shutter button is a bit squirrelly at times.
But the phone app is frustrating, and it flat out doesn’t work with my Sony A7RII. The time lapse feature acts like it’s working, but the shutter never activates. Even the single frame option doesn’t work—the phone just vibrates without doing anything. There’s no troubleshooting on their website, so there’s little I can do to see what might be wrong.
I get that Sony’s stuff is harder to work with than Canon or Nikon, but if you can’t make it work, then you shouldn’t sell the product for that market until it does, flawlessly.
I’ve updated firmware on the device, and maybe some day an update will fix the problems, but more likely, the Spark will end up in a drawer, forgotten.
As I said, I love what these guys are trying to do, and I’ll keep working with my Radian.
