Speaking of TC's, my R5 + 500mm f/4 L IS II USM + EF 1.4X III detail is ridiculously good.

But I guess that's not comparable to an RF 100-500 and FYI, I don't consider the RF 100-500 or most zooms to be ideal with teleconverters, sure, the results are okay but sometimes it's just better to crop, you're now shooting at what? f10? How much ISO do you now need to compensate in a lowly lit area, under trees, in shadows, in the evening? Yes new cameras have good ISO capabilities however, the R5 still isn't the 1DX in terms of low light and you will see a hit on sharpness due to your bumping up ISO high, but if you need that reach and still get the shot, that's great.

Side note you can pick-up a used 500 or 600 for around £5.5K - £7K, the RF 100-500 is already almost twice the price of the Sony 200-600.

I've had good success even with the 2x on my 500/R5.
