once bitten twice shy....as my old sigma 70-300mm APO lense was made obsolete by canon DSLRs err99.....& sigma no longer re-chipping it.
just wondering if any canon user still encountered any err99 on the new DC lenses....just in case buy liao kena err99, etc.....
also, how about the Tele-converters, either sigma or canon, any problem?
