Anyone faces problem using Sigma lens?

[Galdor]

hey galdor, u can send the lens in for calibration at sigma for no charge at all. i sent in my A700 and 24-70mm and got it back in less than 2 hours. now, it is almost perfect except for the inherent softness at 2.8

Thanks for the info bro, I've brought it to them before and they mentioned that they have to order some parts for the calibration since it's an old lens. Anyway I have sold the lens.
