Since you state there are Tamron lens problems with Canon or Nikon bodies please tell me which ones they are? I have never heard of Tamron having compatibility problems. I own a Tamron 20-40mm F2.7-3.5 SP lens and it has worked on all my EOS bodies from Elan IIe, EOS 3, to 10D and others without fail. Allegedly Tamron uses the Canon AF code for which they pay Canon to do so to ensure 100% compatibility with AF lenses, so please substantiate your claim. Peter K
