I would jump on the RF 70-200 if it had a extension tube available. I use my EF 70-200 f2.8 all the time at sports events with the 2x extender. But, as far as I know Canon doesn't have one compatible for that lens. I have done research, but I didn't realize the focusing distance was that long.... Some things to think about. Thank you for the information.
You are correct that the RF 2X Extender cannot be used with the RF 70-200mm.
Why not just get the RF 100-500mm? That will give you almost the same range as the EF 70-200mm + 2X + EF to RF adapter. The 100-500mm is not much larger or heavier than your combo. Of course, you won't have the f/2.8 aperture the way you do now, when using your 70-200 without the 2X. At the short end the RF 100-500mm is f/4.5, while out at 500mm it's f/7.1. It's actually f/4.5 from 100 to 150mm, f/5 from 151 to 253mm, f/5.6 from 254 to 362mm, f/6.3 from 363 to 471mm and f/7.1 only from 472 to 500mm. So it's almost a match for your "140-400mm f/5.6 combo" for much of the focal length range. At 300mm and upwards image quality is certainly better with the RF 100-500mm!

If I were still shooting weddings or similar portraiture the RF 85mm f/1.2 would be at the top of my list. But I avoid weddings now (
), so my choice would be the RF 85mm f/2 IS STM instead.... much smaller, about 1/3 the weight, smaller filters (67mm instead of 82mm) and very similar image quality. The f/1.2 lens is slightly sharper at f/2, but they are nearly identical at all smaller stops. Not to mention, the f/2 lens has 5-stop IS, is much closer fo focusing (0.5X vs 0.12X) and is less than 1/4 the price of the f/1.2!
Hey, I love big glass! But only if I really need it. And there are things like background separation and a dreamy look that an f/1.2 lens can do, which lesser lenses can't.
There's also now an even less expensive Viltrox 85mm f/1.8 available for RF mount ($400). No IS, but in other respects I've been pleasantly surprised by the the quality of some other Viltrox products I've used. I'll have to check it out more closely.
