Seems to be the lens.  F50/2.8 Macro.  Am going to move lights (tomorrow)
and see what happens.  Haven't seen a spot akin to this since a the early
version of the Tamron macro.

My A100/2.8 Macro does that. It sucks because it is such a good lens otherwise. On my lens, it's a reflection of the sensor off the rear element. If you are lucky, it will be off the filter you were using.
