Sigma Lens question.

[dizidav]

I have a Sigma 400mm Prime lens, it works fine on my Canon 20D, but brings up Error 99 on my30D, anybody any ideas on this, I have had a look at the Sigma site, but it dosent seem to list this lens.

probably need's to go back to sigma to have something done to it, the name of which evades me but had to have the same done when i bought my sigma that was used on a 10d and stuck it on a 20d, re-calibrating or re-chipping

Yep, needs rechipping.
