I purchased an Mp6(2013 model) over a year ago. The last few pulls all my morning pictures were foggy and blurry. I told them about it and sent it in.I just received a brand new MP8! Thanks for the great support!
Depending on where it is and the weather may not matter. I have a cam that's always down in a bottoms next to a ag field and it's always got fog or blurred in morning with right weather conditions. Hopefully you don't have any more problems though.
