Hard to go wrong with any of the listed cameras. I am partial to the Sony and Panasonic series of cameras, although Canon and JVC do a great job also. Just make sure that the lens will do what you need and that you have a pair oftghe highest capacity batteries that you can afford. Maybe a car recharger in case you will be driving for long periods from sight to sight. An aftermarket charger will usually have an AC and car DC adapter with it. Don't forget a lightweight tripod if you can squeeze it in.
