Hi everybody, my aim was to go to Tanzania this summer; but there are a few matters. All I have is: Xti + tamron 17-50 2.8 with UV and CPL + EF-S 55-250IS 4-5.6 with UV + 2gb lexar pro 133x + 8gb a-data speedy + tripod + camera bag. Do I really need the battery grip, or a second battery will be ok? Do I need more space for storage? I'll take my 30GB Ipod with me and I have the tool to transfer pics from the camera to the ipod without a Pc, but it requires such a long time. Is the 55-250 long enough?? I can't afford the 100-400! I will probably sleep in a tent...how long before recharging the batteries? Will I be able to charge them everynight? Shall I buy a small and tiny tripod? Mine is quite big (even if low-weight) Any other tips and hints??
