I am having an issues with oddly out of focus video like in this video. I've had some much much worse than this. Here the center is focused but every else is blurry.
I have taken other video where this does not occur even though I don't touch any setting changes other than shutter speed.
At first I thought I had something on the lens but no this problems occurs a lot and I always quickly store the OP back in its case after use.
