Jim, needless to say, it is another cloudy, rainy day in the PNW so have just taken some test shots with my 1D4. The AF in AI Servo works this time, and AF in One Shot mode works with a Tamron 1.4x DGX TC.
Hopefully will get to test with 70D tomorrow.
Just for anyone\'s interest, the serial number on my first copy was 0018XX and on this copy is 0070XX. Seems to confirm this is from Tamron\'s second shipment to North America.
