Well, it's been forever since i've last posted.. thought it was time to ask for some purchase advice. We are headed to Yellowstone the first week of June. This is our first time for a family vacation, as well as traveling across the country. We have never been to the park before and plan on doing many things along the way (Capulin Volcano, Pilot Butte Wild Horse Scenic Loop, Grand Tetons, and of course as much of Yellowstone as we can see in 5 days). The one issue i'm having is regret.. I know that with my current gear, i'm not going to have enough zoom to really get the animals off in the distance (my longest is a 55-250). I originally wanted to get a new camera (considered the 60d) but read up on investing more in a lens as opposed to a body. I am considering getting the Canon EF 100-400mm f/4.5-5.6 L IS if I can get the funds together. I don't know how much weight that will add to my 450D and I am now one to really carry a tripod with me (I know I know.. ) I know i'll bring one with us, but majority of the time I will be shooting without one since we will be doing a bit of hiking. Any advice? I was hoping to stay under $500 with a lens purchase, but I can only find the 100-400 for $750 used on Amazon (and even then I am a bit hesitant to buy a used lens). I had looked at the 70-200 as well, but don't think it will give me enough zoom either. Do I have other options for zoom in a reasonable price?
