Tested the lens, it is ok. The camera is functioning aok as well. maybe a fluke?
Maybe the photography gods telling me to find my knitting needles and that I have been a very bad knitter since I have barely knit a thing since I returned to photography?

Seriously though, I guess I won't worry about it unless it happens again.
But, if any one does come up with a reason, I am open to reading about it!

Thanks for all of the input/response!
