I was talking to a camera store in Calgary about my Sigma 18-200 Sigma lens which is being sent back for warranty work. The sale guy told me Sigma could calibrate my lens to match the particular camera I have, (Nikon D70S). He included this in the work order.

I bought my camera and two lens from these guys so I feel quite comfortable with the info I get but.... *huh?* I've never heard of this.
What do you think?

Mel;
thanks for this.
I learned something new.
I got a reply from Sigma:


Calibration are for lenses that may be exhibiting a front or back focus issue.
If your images are looking ok and not out of focus then no calibration or adjustment is necessary.
If you do have focus issues with your lens I would recommend that you contact Gentec International as they are the distributor and service center for Canada.
