I recently bought a canon t1i with the 18-55 kit lens. i already have a bag, a 16GB card, and an extra battery. I am going on a trip here soon to tennessee and then to north carolina, and will be shooting the whole time. I am wondering if i am gonna regret not have a zoom lens to have with me. I dont have a large budget so im only looking to spend maybe 200 bucks if i need one. im also looking at getting a couple filters such as a circular polarizing filter and an infrared filter just to mess around with. CN: what do i need to go traveling with a canon t1i kit?
