Has anyone sent a lens (and body) to Sigma UK to be calibrated?

What was the turnaround time like and did they do a good job?

I've just received a new Sigma 30mm f/1.4 from my insurers and a focus adjustment of -10 is not enough to get it sharp.

TIA.

I've just answered the poll honestly.

I don't own a K-r.

The poll could have perhaps done with a little more thought.

That's the most amusing thing I've seen in a long while.

Does it grate cheese, or do anything else useful?

Are you sure you're not ballsing the whole thing up in the first place by 'recalibrating' your lenses.

Seems like a huge opportunity to bias your tests to me. A little knowledge is a dangerous thing and all that.
