Does anybody know what happened here? It is one of about 6-8 photos out of over 700 taken on the same morning. This is the first time I have experienced shots like this. In Lightroom, the metadata shows it to have been shot at a speed of 1/1000 sec and ISO of 100. The F stop and mm numbers are blank. This was one of two in a row. The shots before and after of the same bird are fine?
