In your opinion what's the best camera for filming hunts?
The Kodak Playsport Zx3 is a great camera for filming outdoor hunts. I picked a used one up on ebay for about 60 bucks. They film in 1080p HD and it is great quality. The only negative side to the camera is that it doesn't film great in low light conditions, which unfortunately is when much of hunting happens at dawn and dusk. One thing I made sure to do is buy the Zx3 and not the Zx5, mainly because the Zx3 has a removable battery pack where you can bring an extra into the field. Hope this helped.
What's the price point? The best are 15k-20k Sony or Panasonic
I have seen a number of small cameras that are imbedded in sun glasses or can clip to your hat. They have been showing them at a lot of events around Alabama
Lots of great options out there. I have a Canon GL2 that is a good camera, but it is not HD or the cheapest. Whatever you choose be sure you get one with a Manual Focus option and look into a shotgun mic or something that will pick up sounds better than the onboard mic.
