So I have been looking at purchasing a new lens to open new possibilities. I currently have the EOS XS, with the standard 18-75 lens. I have been looking at both wide angle lens and telephoto lens. What would be the best choice? I know canon has a 75-300, but there are mixed reviews. I know you get what you pay for, but I would like to keep the cost down. That said, I am willing to spend more than the very basic lens. I want something that will last a while without my wanting to replace it 2 years from now. Any pointers? Brands to watch out for? In the telephoto department, I am looking for atleast a 200mm zoom. Nothing less. And for the wide, I would like a higher speed for low light shots. Thanks for any help in advance.
