Re: Calibrate Sigma 18-35mm (Nikon)

OK. I think Sushieater covered the subject in his post so not a lot to add.

If after the infinity calibration,  the focus is still in-accurate under the same lighting & target ( by this I mean that you get the same degree of focus discrepancy in multiple "runs" for the same distance (e.g. at 0.9m , 3m , 5m etc)) or If it is inconsistent at the same distance (e.g for different runs at 3m you get varying degrees of in-accuracy) then I am afraid you will need to make contact with Sigma.
