Hello everyone,
I bought the Sigma 17-50mm f2.8 recently and I've had this issue where the camera always focuses at the back of the subject. Has anyone else faced this problem and how did you fix it? I'm using a canon 40D and micro adjustments are out of the question for this camera. Any ideas? |

send to Sigma service center for calibration done on the lens
They need your camera and the lens together to calibrate |

yup at PJU.
Just bring the lens and the camera to their service center. They will take around 3-5 days to calibrate. If the lens under warranty then no charge. |
