Does the 200-400 zoom sucks dust? How is the in built teleconverter, useful ? Not sure if I want to use the in built one and make it a slow F5.6.

Internal or external makes no difference - any 1.4x TC costs a stop of light.

I understand that but in the field there would not be enough time to remove the lens (in dusty surroundings), put a teleconverter and then attached the lens back, by that time, the tiger would be gone home for dinner.
