“ Ah quindi anche con l'anello originale canon r/ef i tamron non funzionano?...e com'è possibile visto che I tamron ef hanno la stessa montatura che i canon ef? „
Non è una questione di non entrare nella baionetta, il problema è l'essere o meno compatibili con l'AF delle R, il Dual Pixel, introdotto solo sulle reflex più recenti per l'uso in Live View (e ricordo che sia Sigma sia Tamron hanno dovuto lavorare di reverse engineering per far funzionare le proprie lenti sul mount EF).
Sia Sigma sia Tamron dicono che le lenti non compatibili con il DP si possono usare sulle R...in manual focus.

Sigma note the following:
DC Lenses – You'll need to set 1.6x crop manually in the EOS R menu – they're designed for APS-C bodies! They hope to bring out a firmware update to this.
And to quote Sigma on these exceptions:
SIGMA 24-70MM F2.8 DG OS HSM | ART
It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens's OS function is in operation.
It may stop the focus driving from infinity to closer focus distance while shooting video with AF.
SIGMA 60-600MM F4.5-6.3 DG OS HSM | SPORTS
It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens's OS function is in operation.
SIGMA 100-400MM F5-6.3 DG OS HSM | CONTEMPORARY
It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens's OS function is in operation.
It may stop the focus driving from infinity to closer focus distance while shooting video with AF. „
