Sony 200-600 vs 100-400 + Birds in Flight (Sony a7III)

A comparison of tracking birds in flight with the Sony 200-600 G and the Sony 100-400 GM teleconverter, shot on the Sony a7III. 👉Discover our new community forum: You can find detailed image comparisons between these two lenses on my website here: Note: I mentioned that I used tracking sensitivity 5 in the video.

But even with it set to 5 both lenses locked on well and there were probably only a couple of instances where having it set to 1 would have helped.
