It's the new targeting system!
Kidding, seriously though I would call customer service. Looks like there might be a micro drop of water between the lens and the image sensor or something (or otherwise a problem with the lens/sensor).
@fburnham Ever hear back from support on your issue?
You might be surprised. If the moisture is held between the lens and the actual Image sensor it would already be so thin as to not spread out.
Take for example a 2 megapixel image sensor; the entire surface area of the sensor can be only a few mm in width/height, so even a near imperceptible spec of liquid could cause a significant size obstruction as your seeing.
