I am a new member and this is my first post. I have a Canon Eos Rebel camera with a broken kit lens so it is time to spend some bucks on a lens or two. I take mostly landscape shots so a wide angle lens is perhaps the way to go?? I'm not sure I understand the difference between a zoom and a telephoto lens, which is embarassing since I am an optometrist and actually had a fair bit of training in optics once upon a time. Anyhow, I would like good lenses so they will last a long time (as I improve) and I have a reasonable budget. Suggestions please! And thank you.
