Hi, I live in New York City and have an interest photographing objects (everything is up for grabs) that are up close, far away, moving, landscape, ball games, and shots of people in various neighborhoods. Of course, I will be using it while travelling anywhere I go like Morocco. I'm planning on purchasing a Canon Mark II and was wondering about the lenses that could help me capture my desired images. Since the Mark II is already expensive for me can anyone recommend a lens that combines zoom with telephoto or is that not a reality? If those are sold separately, then what are good choices for the three lenses I could use that are below $800. Thanks!
