With the TC that works out to f/5.6 vs. f/8 and saves me a stop of ISO… Those just answering your question with regards to flight photography.

For general bird photography throw in the ability to use the 400 DO II/2X III combo at 800 for hand held photography….

Artie, Given the flexibility of the 100-400, what are the reasons you’d opt for the 400DO other than f/4 vs f/5.6
