I recently bought a Sigma 50mm 2nd hand and fear it's got AF challenges as quite a few of my pics, particularly when taken at more than 3-4m away, seem to have randomly back or forward focussed. I've checked the focus point in DPP and the focus definitely isn't right in the end picture. However, I have MF calibrated the lens (-7) and it seems to be good for close up pics.
The person I bought the lens from never registered the lens for warranty with Sigma - he also gave me the original purchase receipt. I've since registered the lens and have had the 3 year warranty confirmed by Sigma themselves.
My question is, if I send the lens in, the name & address on the original receipt is clearly different to mine. Will Sigma be bothered about this (I could say a friend purchased it for my birthday if needed) or are they just bothered about having proof of purchase? Never had to send a lens in for repair/calibration before, hence the question.
Thanks
