I'd like to see that as well. I saw Tactacam at the ATA Show comparing their camera to the GoPro as it shows the "fish eye" look on deer at 20 yards. The GoPro made the deer look like they were 100 yards away while the Tactacam looked like an unzoomed camera at 20 yards. But, I'd imagine they had the GoPro set to Med, if not Wide. I'm going to do some testing with my GoPro on narrow and we'll see how it looks. I'll post it up when I do it.
Interesting. I remember reading rumors of a cubed GoPro a while back that some people dug up. This must be it. For me, I don't see a fit for it. I keep spare batteries for my GoPro, and use them regularly. I have the Hero 2 which has better battery life than most 3's and 4's, and I still switch batteries out often. I could see the size form factor and the not needed a waterproof housing begin an advantage for some specific applications, though.
I think I'm buying one. I mean its so small, it would work awesome to mount it to your riser like some guys do with Epics to get a video of you drawing the bow back. I thinks its awesome for self filmers wanting to get multiple angles
