Just got an EOS 10D, I planned to use my existing lenses, these are Sigma
28-135 and 70-300, Because I had read about some compatibility issue with
Sigma lenses and the possibility of them needing re/chipping, I contacted
Sigma UK with model and serial numbers and they confirmed that both lenses
would need re/chipping at £32.99 each ouch!!!
However now I have the camera I have tried both lenses and cannot find any
function that does not work, anyone know what the compatibility problem is
supposed to be and what is not supposed to work.
