Report "Hi, i have a sigma 300 2.8 lens i used on my EOS 1N. I finally decided to go digital and have an EOS 10d, the lens just brings up Error on the 10d . Itook it back to Great Western Camera's who sold it to me and they sent it to Sigma, who told me it cannot be re-chipped, i have since been told by another camera shop some independant repairers can do the replacement ,if so have you any names and addresses. The lens is too good to mothball and a new lens is now out of my price range. Any help would be welcolm, Cheers Dave"
