What's the battery life on those? I'm in the market for one, a local shop up here sells a Sony with a wrist strap screen and controls for $199 Canadian.
OK, I'd say the battery life for a single battery on the Afunta might be about 1.5 hours or so. A 32 gig microSD card will store about 4.5 hours of video at 1080P resolution, at 30 frames per second. You can buy additional batteries for the Afunta camera and have them charged up and ready to go. I still need to come up with a good setup for containing all of the pieces/parts while in the tree, to prevent dropping them.
Let me say this about your $200 Sony sport cam. It sounds like an almost ideal setup. With my Afunta, I always have to take off my helmet to access the controls to turn it on and off. With your Sony, you get to leave the helmet on. Because of the trouble I have to go through to turn it on and off, I sometimes tend to just turn it on and leave it running, which ends up killing the battery for when you really need it. With the little screen on your wrist, you also get invaluable feedback with regard to what the camera will be looking at, whereas I operate in the blind, and only find out later that it was not pointing where I wanted it to be.
The only thing I don't like about Sony is the fact that they fairly frequently want to force you to use their proprietary memory card formats, instead of using industry standard SD cards or MicroSD cards. Their cards being proprietary means that you'll be paying more for the media, probably.
Another thing I have to say about Sony cameras, and this is a spec that you'll need to check for, is that they tend to use Zeiss lenses in their cameras. Zeiss lenses are some of the best and sharpest lenses made. All in all, sight unseen, I think you'd be happier buying the Sony camera with its set of kick-ass features than you would with the Afunta camera. Down the road maybe you could buy some of the cheaper Afunta cameras to have available to mount in the tree, to catch some additional camera angles, if you felt like it.
I'd say spend the extra money on the Sony, and avoid wanting to rip your hair out.
