guys, help me
which of this lens is the best?

sigma 70-300 APO DG macro f4.5-5.6
tamron 70-300 Di macro f4.5-5.6
new minolta 75-300 f4.5-5.6

all lenses is on the same range price (less than 1k)
same aperture and focal lenght
but the sigma is APO
and both sigma and tamron are macro
minolta had a great reputation in dyxum, but for the price, is it worthed?

very confusing

I need your review, thanks a lot
