Macro Photography, also known as close-up photography, is the photography of small objects. A macro lens is a lens that offers a magnification of either 1:1, (1x) or sometimes only 1:2 reproduction.
I'm looking for a macro lens. I have 28-105mm Nikkor which gives me 1:2 Magnification Ratio (whatever that means). I found another lens, Tamron 90mm Macro, which has magnification ratio of 1:1.
