iphone camera issue

[widgeon13]

I have taken many pics with the iPhone and never had this problem but just recently it is auto focusing on the plexi windows of the plane so I get a very blurry pic. It used to focus on infinity and all my pics would come out nicely. Anyone having a similar issue and any idea how to effect a change. I'm not using the zoom, it just happens and I can't tell until I download to the computer. I have tried to have the camera close to the glass and also a few feet away and the problem seems to be consistent when close to the glass but if I back it off I end up with partial shot inside cockpit.

Here is what I am getting more frequently now.


Took this a minute after the one above.


Here is what I used to get regardless of where I held the iPhone.
