If you want good zoom buy a screw on lens. Most cameras come w/ a threaded lens and you can buy one to fit pretty much anywhere online. I have an older sony w/ 25x optical zoom and i bout a 5x telephoto lens for bout $100. So now i can have an effective 125x lens. Its great for late summer scouting, but only at long range (you get the tunnel effect if your not at about 18x zoom). But if you want to use it for filming durning a hunt i suggest buying a 2-3x lens then you dont get the tunnel effect. When looking for a camera check the lens diameter thread, 37mm is typical, check online and see what type of lenses you can buy that fit it.
I got my add ons for my camera here:
