Excellent reply

Indeed a non-reporting TC works very well. I was going to question f8, but come to think of it, I usually set my 400/5.6 and 1.4 tamron TC at f6.3 and since I lose 1 stop, that is f8 so I agree with that too. As I’m usually after birds I keep the TC on most of the time, you can never get close enough, and just try and keep the speed up, I use a monopod, except for birds in flight, and even that’s possible with the TC on, just bang away till you get a sharp one. I’ve tried the alternative with the bare lens and more cropping, and for me it’s worse.
