haiz, darn, went to Sigma Service center after school today to fix my 17-50 background focusing problem. reach there then i found out i need to bring my camera along too.

so i asked them if i can bring tml, then found out servicing needs appointment

. so i say i will make an appointment tml, and they say cannot

, so i say thursday, they say cannot, so i say friday, they say can. also took their updated cataloge to drool over the lenses.:xmas: cant believe the size of that 300-800 monster.
anyone has experiences with sigma service b4? the other CSer using this same lens as me said they were pretty difficult and stubborn to handle. right now feeling intimidated by the 1to1 servicing on friday, later unable to re-enact the background focusing problem and end up bringing my lens back.
