I'm in love with the idea of this. Actually pre-ordered one but after a year past the original "ship date" I cancelled it.
I spoke extensively to the soloshot sales crew when it was first announced to understand it:
-Has to be fast enough to follow the action
-Could have multiple tags (I think 15) predefined in the app and just click on the number of the person that has the ball on your phone to move the camera.
-Has a "manual mode" in the app. You can connect from an ipad and swipe left/right/up/down and zoom in and out.
After cancelling my order I've come back to it a few times as again, I'm in love with the idea of it. Unfortunately I dont know its "there" yet.
It does look fast enough to follow the action of a soccer game, though after filming a few games on a manual system, I'm not sure there are many motorized systems that will be able to follow some quick passing without zooming out. *obviously without having used it, this is conjecture.
The tags are $149 each and need to be charged. Not sure of the battery life but I imagine it could be done between games but the cost alone for 11 players would get pricey. This assumes the kids could swap bands as they are subbed out. Most probably you would need 13-14
The app still does not have the manual mode. I believe for my needs (filming soccer), this will be the route I need to take. My concern is the lag from me inputting directions on the ipad to the camera actually moving/zooming. I've used a couple of "remote cameras" (zoom/start/stop only) and there is typically a 1-2 second lag for any interaction. That would be unacceptable for filming a game like soccer.
I have seen soloshot 3's for rent and when the app supports manual mode, I will probably take one for a spin.
