[Leica] IMG: this is VERY strange (OT)

[Jim Nichols]

Adam, I was aware that a Blue Sky/ f/16 image on my X-E1 shows a couple 
of spots, has for more than a year, but never shows up except in an 
occasional skydiver image, where I just clone it out.  But, seeing 
something similar with the X-T2 was a surprise to me.  Thanks for 
raising my curiosity.  I have never cleaned a sensor.

I then increased the sharpness with Focus Magic.  As you can see, I have one large spot near the center and two smaller ones in the top right, all of which I was surprised to see.
