I am fairly new to DSLR's and I need your advise on buying a new lens for my Canon EoS 300D. I am looking for a lens with lots of zoom and maybe a Macro Feature. I am also wondering if its possible to combine to different lens. Also I was looking to buy a 2x teleconverter to go on the new lens.

Please give me your opinions and advise on these 2 items
