Blows me away how good this set up is with the 2x extender, these prove the point very well ;-)

I did a side by side with my RF 600F4 and the 100-300 with 2x TC, and was also completely shocked how close they are in sharpness. The 600 is better, but its not "WOW" that's a big difference better! Its slight.

With a 1.4 I cannot find any difference in IQ from the bare lens. its really an amazing piece

Great lens maybe? But if someone can drop 10k there are other lens combos that would rock out. But maybe an all in one 100-300 2.8 is worth having?

There’s no maybe about the 100-300 being a great lens - it just depends on what someone wants or needs. For me I wanted a fast zoom (using TCs when needed) to travel Southern Africa with vs bringing a larger prime like a 400mm 2.8 or 600mm 4.0

Definitely. Replaced my 400 f/2.8 on safaris. And added greater flexibility.
