Sigma 70-300mm f/4-5.6 DG Macro APO

Its a bad lens if you think it will shoot like a prime with astounding speed and accuracy and be sharp at f5.6 300mm.
However if you shoot within the limitations of this lens, you will find that its a great lens vis-a-vis the cost that sigma is selling it at. It is definitely better than any 70-300 in the market. The tamron is the closest but suffers from excessive CA and noisy motor.
I use it with my D50 and I prefer shooting at f/8 at 300mm. It is quite sharp then.
The macro is relatively good but only for flowers and butterflies.
I am a nature photographer and I feel its a great companion to have on the treks for those who like to shoot everything from the moths to the mammals.
