Thank you for your replies. I shoot mostly with a 28-105, 28-80. Basically anything. Haven't really 'specialised' yet. Heard n read many good things abt 85/1.8. Does the 105/2.8 macro fill in the functions (namely, portraiture) of the 85/1.8? I'm thinking of using it with the D100 to take pix of my daughter.
