seen this lens in the web Sigma APO 70-300mm F/4-5.6 DG Macro. how come this is a "macro" with such a long zoom?

I have been reading up on the sigma macro lenses. It seems that some of the sigma macros are not true macros, as in, they are not 1:1, the simply have the ability to focus at a close range( ie they have a short min focus distance)

hehe, think S n T marked all their lenses with Macro --- for original definition of Macro lens-- there must be at least one floating element in the structure, so nowadays, things changed a lot. -- even a magnification glass can call itself “ Macro” liao:bsmilie:

and a macro shot means at least 1:1 or even big @ beginning, now it changes too. --- changing with time, hehe

For Sigma and Tamron to have macro on their lens mean shorter focusing distance likewise macro lens but not yet to true macro.
