Thanks for sharing. I am currently using EF 100-400+1.4III + adaptor. A bit front heavy.

The combo has a bit more reach at 560mm than the 100-500mm at the long end.

If I go with the 100-500, I will not use the RF 1.4x because it is darker, so that 60mm is lost

Not at all - the EF 100-400 is f/8 at 560 with the 1.4x attached. The RF 100-500 is f/7.1 at 500.
