Photozone.de formerly reported compatibility problems between most older Tokina lenses and the EOS 50/E and 500N. This is not verified (by means of that I can't seem to find anyone else who'd confirm those issues from first hand experience) and thus a more or less curious information. Also reported were the 2.8/100 (problems with EOS 100), and batches of the 2.6-2.8/28-70 and the 2.8/28-80 (problems with EOS 1V, 3, 30 and 33).
