I really did try to search this but did not find much as maybe my parameters were weak. I purchased from a great FMer what has to be one of the nicest 300 f2.8 non IS lens left on the planet. It could pass for a lightly used year old lens. I have decided I enjoy trying to shoot small birds in trees and some ducks and geese in flight. The only time I usually get to shoot is very early morning so I don't often have perfect light. I am shooting a 7dII. More reach would be very helpful. IS would be helpful for the birds in trees. But the f2.8 is helpful to get shutter speed up.
If this was your two choices, what would you choose?
1. 7dII + 100-400II
2. 7dII + 300f2.8 + 1.4 extender
Your thought are appreciated!!

This is one of the classic lens conundrums. To start out, you can be assured that both options are capable of producing excellent quality photographs, so it isn't a question of one being "good" and the other being "poor."
The most critical differences here are not optical. They are functional.
For example, if you value flexibility of being able to work between 100mm and 400mm, the zoom wins. If you only need to shoot long and only at 300mm and 300mm plus the 1.4 TC, then the zoom might win. If you need f/2.8, the zoom doesn't have it. If IS is valuable to you, the prime doesn't have it. The TC gives you some flexibility with the prime, but you have to remove the lens and fit or un-fit the TC when you change focal length. The zoom makes the range of focal lengths available immediately. If it matters to you, the zoom packs smaller than the prime.
A good way to think of this is to take supposed image quality out of the equation. Imagine that IQ is exactly the same on the two lenses. (It isn't literally identical, but both are very, very good.) Now how would you choose?

Exactly. In decades past the IQ difference between zooms and primes was greater than it is today. But a missed shot from being too tight is still a missed shot. A prime lens of shorter focal length will miss less of those shots, but cropping more than a small amount quickly negates the advantage of the prime. With fine lenses like the 100-400 IS II, 200-400/4 w/1.4x TC, and 400/4 DO II, the choices are more complicated, but it is great to have those choices!
