No, that's what so infuriating. One day I go out and focus is junk. The next I shot under the same conditions and it's spot on. Making me crazy. Tam says send it back; if nothing else it will get a clean and polish.
Normal mix, but got a new first sighting at the Arb, a spotted towhee. Been trying for three days to get a shot, but he was too fast flitting through the bushes till today. Not great, but at least it documents it.
