Regardless. The answer is to buy a Sony.... 🙂
I am just kidding!!!!
Post an image taken with it, go into options and lock the mirror up (or put it in live view mode) without lens on it and look at sensor no touchy touchy though... Dont go all fingers and thumbs messing your sensor up thinking you can shift it.
I think you may need it looked at.
Hope it works out ok.
