Regarding your Sigma lens, if you don't have the manual at hand you can check at Sigma website about the MFD. Please select the correct lens, compare all the letters at the lens barrel with the list, there are 2 recent models. One is labeled "Macro" and should have a fairly short MFD, so maybe you got the other one?
Ok i have check the sigma website...Minimum focusing distance is at 40cm...then i believe i have stand too near to the object...as i think i am not 40cm away from the object...that why out of focus....and also if i am far away from the object...does it mean i can get a better focusing and also a sharper image???

Cant do manual focusing????? Turn the focus ring on ur lens?!?
Stop down and ur autofocusing will work better. Correct me if im wrong. 500D has a f/2.8 cross type AF sensor in the middle. The rest are not as good. so AF will work best if and only if ur using f/2.8 and slower, and u have selected the center autofocus point.
u mean the f2.8 af sensor is in the centre autofocus pt?? so if i want have to use other pt to focus i will have to increase my f number??
shoot further away?
then crop the photo? u dont need to fill all ur viewfinder with the image u know?
ur lens will still hv to be fast enuf at wide open for the more sensitive sensor to work though. sry for being confusing :S
