Digital BW, The Print

Paul, 

No--that's not true--many are using Sigma, Tamron, Tokina lenses on the XT with no problems whatsoever, but you may have to have it rechipped by Sigma--which they do gladly.  Many have had older Sigma lenses rechipped.  Get in touch with Sigma and see what they say.  Also--Error 99 is an error on Canon cams that covers a lot of territory.  You may just want to try using an eraser on the contacts and try again.  It may just be something small like that--which is what I would try before sending it to Sigma--or remounting it.  Don't worry about it not working with Sigma lenses.  Sigma is usually the one with the most problems (others think that Tamron and maybe even Tokina have a 'quiet' agreement with Canon so they don't have to backward engineer, but Sigma is very good about dealing with these problems.

  Well, Canon has joined the club.  The new Digital Rebel XT gives me "Error
  99" with my Sigma 24mm.  That code means the camera is incompatible with
  many (all??) third party lenses.
