Hello, I'm looking to buy a small, lightweight HD video camera to take with my on my backcountry hunting trips. I am most interested in a good optical zoom (for filming the big ones from long distances), durability, weather proof, small in size. Does anyone have any good recommendations on which camera would be the best, and where to buy it? I'm trying to avoid just walking into walmart or best buy, picking one, and taking my chances. Any input would be appreciated. Thank you for any help!
