Yep these horrible pictures posted taken under terrible lighting, no exif data, nor a hint to the forum where the focus was.
For that matter hollow complaining about the most uploaded version of iPhone yet on Photo sites that don't compress your shots like so many here have linked the shots they are complaining about.... yet they are not aware their pictures are compressed. While there very well might be an issue I have yet to see many true problems with pictures other than the way they were taken.
33 page thread and the better Apple Centric web sites/forums have totally ignored it has anyone wondered why? Yet the most respected testing sites have not mentioned anything in their testing other than heavy handed jpg conversion nothing those in photography haven't seen before ( Nikon/Canon).
Good luck to those that truly have an issue.
