I've just got an XT, moving up from point and shoot digital cameras, and am wanting to learn more about photography, so I'm definitely a beginner. Anyway, I have some old lenses from a Canon- a 100-300mm 1:5.6, and a 35-70mm 3.5-4.5. I don't want to spend tons on lenses, I just want some decent ones to learn on until I decide to move onto a better system. Are these decent lenses for a beginner to learn on? Should I look into getting an other ones to round out my collection? I'm going to be taking a lot of landscapes, so I was particularly interested in knowing if I need a more dedicated wide angle lens that won't break the bank.
Thanks!
