I fitted this combination on the RP while questioning the idea of trading this for a RF 800mm.
I believe the 100-400 is a better lens. But for birds, 400 is somewhat short.

Suggestions and opinions?

Thanks.

I have the original 100-400 and tried it with a Canon 1.4x (II I believe), but was not happy with the results so I can't imagine a 2x would be very good.  The 800 would definitely be better in terms of IQ.  But with either combo you'll need a lot of light.
