Did you use a hood with that shot? I have found that "bloom" sometimes come from the lack of contrast when not using a hood, and having lots of light coming from an angle.
Can you do some ISO 100/200 test shots with the lens at F2.8? It's difficult to tell if there is any missed focus in that image due to the subject and high ISO. If the lens is somewhat sharp but slightly mis-focused, it can just be a minor focus correction to make the lens acceptable.
I can post it before noise reduction too.
Lets see, Yes I did use a lens hood and the light was coming into the room to the camera left (as I'm sure you can tell) so definetly from an angle. along with some lights on the ceiling. I inspected the image at full size to see if it missed focus too but coudln't decide where the focus fell at all, it all looks soft to me.
I will try some test shots at a lower ISO and re post.
thanks!
