As with lenses i am complete noob! I have bought Sony A200 as i am on tight budget, with standard 18-70mm lens! I am not really satisfied with this lens as there is not enough zoom and no macro capability at all! What i am looking for is all round lens for beginner with little zoom and some macro capability! I have went thru forum and this gets even more confusing as i am begginer! So I have rounded up my search to Tamron 70-300mm F4-5.6 Di LD Macro or Sigma 70-300mm f4-5.6 APO DG as i read they good for the price and they offer some zooming and macro goodness. And here is the question as i will stick with them for few years, will they offer me what i am expecting or should i spend a bit more and go for Sony 70-300 equivilent? Or maybe should i go and buy something like this Sigma 28-300mm f3.5-6.3 DG? Any suggestion and help will be highly apreciated!!
