I'm been thinking about x2 TC III for my 400mm f2.8 IS II. It would be nice to have 800mm range for wildlife. I'm little concern about IQ loss
Don´t be. It is still great. Take it to a store and try it out. You will be very pleased. The attached image is a 100% crop
5DIII, 1/1000s, f5.6, ISO400, handheld.
