One of the things that I get asked most is what lens do I use and that actually depends upon the situation.
When I am shooting portraits outdoors I am normally using my 50mm F1.8 but in studio I shoot with my 24-105mm F4.
The lower f-stop on the 50mm is awesome for adding some beautiful bokeh to the background of my subject and the 24-105 gives me the perfect range to capture either full body or close up detailed shots of mouths, eyes, etc.
