However, some 3rd party lenses continue to work just fine, so it seems that Sigma just didn't do a good job of making their lenses "Canon EOS compatible." ------------------------------------------------------------------------ --------- The only lenses that have not needed to be altered were Tamron. Sigma, Tokina, and some other small players need to be re-chipped to make them 100% compatible. Like anything else, I would imagine Canon charges for the code needed to make 3rd party lenses 100% compatible. So let me ask this, how many of you are running MS-DOS programs on Windows XP? Typically you upgrade as you go along so if a 15+ year old lens is not compatible its much the same as wondering why you may run into issues using the MS-DOS version of Lotus 1-2-3 on Windows XP. Better yet, how many of you are upset because your 8-tracks will not work in your new car's CD player? Did you expect the car manufacturers to have an adapter? Give it a rest, complaining will not change things. At least Sigmna is doing what they can and rechipping the more modern (less than 10 years old) lenses, as it Tokina. And if it were your business would you really want to make a lens you sold 15 years ago compatible since you would lose money in doing it and lose a potential sale of a newer lens. After all, it is a business.
