MTF ratings of modern minolta lenses?

I am looking for ratings of newer minolta lenses, for example the 28-75mm f/2.8 D or 100mm f/2.8 macro D. Can someone suggest where to find this information?

Hi rohit
there is a lot of info and useful links on www.dyxum.com
Hope this helps

I am looking for ratings for mf sigma 300mm f/2.8 is it beter than tamron sp 300mm f/2.8 ?

These two lenses have been extensively reviewed in many sites including photozone.de...........the 28-75/2.8 D has a sibling called Tamron 28-75/2.8.
