I know it's been a while since anyone has posted on this thread but just in case someone browses through who is wondering about portrait lenses. I thought i'd mention the Sigma 105mm f2.8 macro. I've used mine on a crop and a full framed body and i adore it for close up portraits indoors and for details such as eyelashes. It's even great for full body portraits outdoors. It is tack sharp, has nice bokeh, has OS and it's pretty cheap at around $500-$600!
