I currently have the 2xTC III + 70-200 II combo and it works well except in low light (as expected). I had previously the 2xTC II and the IQ was inferior to this combo. Still, you pay for having the zoom flexibility instead of prime 400mm 6.5L higher carrying weightmwh1964 said:Had the 2xTC III for use with the 70-200 II, but felt I just ended up with a cumbersome heavy combo. Probably should have chosen the 1.4 EX instead also giving me f4 and not 5.6.
