[OM] E-M5 sensor reflections?

The last couple of days I've been taking photos of the interior of my 
house to make some sale photos for when it goes on the market on 
Saturday.  <http://www.chucknorcutt.com/2712/index.htm>
I haven't done this for about 8 years and I had to re-learn some hard 
lessons on dealing with mixed incandescent, daylight and fluorescent.  I 
probably should have used flash and filters but I didn't have enough 
time for such sophistication.

So, using only ambient light, I ended up with a lot of photos having 
deep shadow areas in an attempt to keep the highlights under some sort 
of control.  Some photos required rather extreme manipulation of 
exposure, shadow and highlight controls in PhotoShop.  It was not common 
but several shots show what I think is a light spot caused by reflection 
from the sensor.  See the left side of the back of my easy-chair in this 
shot <http://www.chucknorcutt.com/2712/familyroom1.htm>  I think it's a 
reflection from the fluorescent fixture in the background.  This is not 
very visible in the the actual tiny images used on-line for advertising 
the house (same size as the thumbnails) but I still found it unexpected 
and disturbing.

I was using the mZuiko 12-50 at 12mm throughout.  I suppose it could be 
this particular lens but I haven't had a chance to test any other. 
Anyhow I've never seen it before but have never pushed shadows this 
hard.  Anyone else seen this sort of effect from the E-M5?
