hey guys, need your help again. i saw this Tamron AF28-200mm F3.8-5.6 LD ASP Super II-Macro lens for sale. i wonder what type of macro shot can it take? comparable to a true macro lens? when i use my 50mmf1.8 or kit lens to take close up shots, i have to shoot at a pretty far distance to be able to focus.. how about this zoom lens?
