Ok so my next question is regarding a good telephoto zoom lens. I'm going in to the brick and mortar store tomorrow to see how much range difference there is between these two. There's a big price difference here $600 vs $300, but I don't mind paying the money for a better lens if it's something I'll be more happy with and be able to get higher IQ pics out of. I've got a Canon XSi and I'm looking for something I can take hiking with me MAINLY for close landscapes... I don't really care for really wide landscapes... I'm more of a cool picture of a tree and a rock in a creek kind of guy ... but I also want to use it to capture some some wildlife. I also plan on carrying a tripod so I can try out some HDR. Wondering if the range of the 300mm will be worth it or not, plus several reviews on Amazon say that IQ drops beyond 200mm on this lens. Is a 70-200 a good tele lens to go with as long as I'm not planning on trying to watch birds from several hundred feet away? Is there another lens < $600 I should consider? (I prefer EF to EF-S, for later body upgrades). EDIT: See some samples of the types of pics I'm looking for in #6 Thanks!
