So, Kevin and Logan have "bullseye" halos which look to me like multiple reflections from a filter external to the camera. What filters are you guys using?
Ben has a strong case of the more complex reflected microlens diffraction pattern. I had a quick play and managed to ameliorate this to a reasonable extent but not enough that I was happy.
I probably won't get a chance to do much more until the weekend and will report back on any successes... or failures
