Hi
i read in a lot of forum , Tamron 28-75 F2.8 is a great lens
i read the optics quaility is superb like the canon ef 24-70 f2.8L and the tamron can deliver the same image quality
well i'm sceptical, doubtful about what i did read
i can't rent a Tamron 28-75 F2.8 because my reseller has every lens (canon , sigma , tokina , tamron , zeiss ....for canon eos but this one
well is really so great this lens , is like the canon 24-70 2.8 , i'm talking about optic/image quality/contrast and af not built quality
thanks
