I just sent back 2 sigma lenses for AF adjustment and routine check-ups, and I got an "estimate" back from them today for $90 + $10 shipping for 1 lens. The other is under warranty.
Does this sound about right for a calibration fix?
There was no information on what they were going to do or what was wrong with it.
I replied to their email with those exact questions but haven't heard back yet.
Anyone that was dealt with Sigma please chime in......
Just thought i would ask here before I send payment.
