For the past 17 years I have been using a Sony VX-DCR 2100E; a great Camera it has served me well but the time has come for an up-grade to HD and away from using tapes.
I would prefer a camera comparable to the Sony VX with as good or better sound capture, would also prefer Sony as the batteries would be the same at least in think so.

As most of my video involves wildlife a zoom not less than X20 is required.

What do you suggest?
