Whatever... I don't think we can help children. If you want our help, try coming to meet up in our outing. I am sure some of us would be able to help you check your camera more properly. However, since Sony say everything is fine, I suspect something else is wrong.
Though... I find it odd that you claimed Sony would need to test the camera body for a few days, yet immediately able to find another lens to test and replied to Titan10k?
and
Looking at the date you posted, less than 1 day different?
No point whining like children (that seems to very post you wrote in this thread). I think, most of us would be willing to try test the camera with our own lenses. Just sign up the outing and do let us know.
Edit: Or... Tell us where you stay, if any of our bros stays near you, think you can ask to meet up and let him check it.
