To look for CA or purple fringe, you need to shoot at day time or with
higher color temp light source, the tungsten dose not do very well. But for
your image, I see something near the center.
Here is an image taken with OM 35-105 zoom wide open. Just looking at the
warm light source it is pretty good too.

Sorry for the poor quality, it was taken at ISO3200 handheld, no NR.
