Where in the Canon page does it mention the issue with Tamron lenses? I have the 17-50 F2.8 VC which was faulty in the first place however this just compounds the issue.
Its a issue previously mentioned.
Previously mentioning an issue is not the same as Canon acknowledging. Canon acknowledged the issue for certain Canon lenses, only.
Precisely my point Cornell. The Canon Page does not mention Tamron Lenses. Now I am not sure if it necessarily has to mention them however it chooses not to and only mentions their lenses. I have written to Tamron Service Dept in the UK with links to this site and await a response although I am not holding my breath. I had my lens with them over Xmas/New Year so I am not sure if they will have made the modification required at that point when they were checking the lens over.
