I just wanted to know which lens most people preferred when using the 1.3 crop camera for portraits.
Set up a target simulating a portrait subject. Place your camera 8 to 10 feet from the "subject". Using whatever lenses you have, find the focal length or focal lengths that allow you to frame the "portrait" the way you would like to. Then you can tell us what focal length(s) you may be interested in and we'll recommend specific lenses.
This isn't rocket science, but you have to make some decisions before we can really help you.
