Rob, 

I was a little surprised to see the same thing you did.  It looks like 
"veiling glare" to me.  I associate it with older single-coated lenses.  We 
all know that Pentax has wonderful lens coating technology; maybe there is 
some internal reflection in the inner lens barrel that only occurs when the 
aperture is wide open?
