Thanks Steve, Denise and Don....
this arrangement is usable only for birds that are relatively still....without autofocus using live view is almost impossible with a littel bird jumping around quickly.
I am going to try the same lens combo with my 1D3, it will autofocus but I expect it to be very slow doing it. Also the percieved "reach" won't be as great since it is 1.3 crop factor.
Hopefully I can try it this week. Mostly I wanted to know if I could get adequate sharpness using the 2X TC
