New venture into Macro
I want to expand my interests into Macro photograpy. Up to now I have used my CP4500 or my 300D with a Sigma 50-500 for small subjects.
My questions are
1.What are the advantages of a dedicated macro lens?
2.Also I don't understand the magnification ratios quoted in the tech specs for macro lenses.
3.Can a macro lens of say 150mm be used for general photography?
Can anybody suggest a suitable lens? My budget is c£300. Possibly either Canon/Sigma/Tamron
