I might be sounding a bit vague but I am relatively new at DSLR photography and am finding lenses even more confusing.
I would love to do Macro Photography. My question is can a Canon 70-200mm f4 lens be used for Macro too, or is it better to go for maybe a Canon ef 100mm f 2.8 lens. The IS version is quite expensive so not sure if I can stretch the budget for that at the moment.

I have the 18-55 kit lens for everyday photography and am not really impressed with that, so any ideas on a walkaround lens would be greatly appreciated. Also, can the Canon macro lens double as a walkaround lens.

Thanks

Lee
