Just an fyi...I have that Sigma lens. It is the best cheap AF macro I have found...not true macro...but pretty decent 1:2 @ 80mm. A good deal for someone who has that spare kit lens laying around.

What do you mean by "not true macro"?

"true macro" is normally said to be 1:1 ratio, so that the object being photographed will occupy the same space on the sensor or film. 1:2 means that the object takes up half the space on the sensor as it does in real life.
