Hi longside 1,
I have purchased Sigma 100 mm lens for my D-70 cam. few month back for Macro photography.... And I double it up as a portriat lens too.... It is a very nice lens, Images are sharp and full of details.....
I am posting my Macro images taken in Sigma 100 mm lens ( Hope If it helps you)
Can't post the portrait, As my subject is not allowing me...
