My tip? Sell it and buy a lighter camera. I had one for a while and while it was a great camera, it was just too heavy to lug around all the time. I always figured it was heavy duty enough that you could beat someone to death with it and then take their picture. I held onto my F3HP for a long time but finally sold it a couple of years ago when it became apparent I really wasn't going to use it and a friend would. I've still got my F5 though- I have no plans to sell it.
