Just great. Had my 150-500 lens about 2 weeks and it fall within the serial number range.

Sent a note to repair center. Will post further info when I know more.

LOL I think all sigma lenses have to be recalled for calibration
It's not just the 50-500 issue anymore

info I got back from Sigma

The defect that they are talking about is complete AF failure.

If the lens is operating normally then I would not worry about it at this time.

If your lens no longer Auto Focuses and you are only able to do manual operation then I would contact me back at that time and I will instruct you on how to send it in.
