When I put the RF 2x behind my RF 100-300/2.8, I get a 200-600mm f/5.6 so for me, not much interest in this lens. That combo is $10K, which is where I'd expect this lens to come (and that's not factoring in US price increases from tariffs).
Hoping for a new 600/4 with a built-in
How disappointing, unbelievable, yea only recourse now for good canon lens is to wait for the new RF 400 and 600, hopefully they get released in first Q of 2026. Its really disappointing that folks reported the 200-500 in the field, what a bait and click jokeWhen I put the RF 2x behind my RF 100-300/2.8, I get a 200-600mm f/5.6 so for me, not much interest in this lens.

Nonsense. They'll just build it in the US entirely from domestically-sourced materials. So. Much. Winning.Truthfully, there is a high likelihood that the purchase of any new Canon gear will be nuked by the politicians.
I really would not count on an expensive supertelephoto lens to impact Canon's market share. If sales begin to slide, they'll do things like lowering prices, expanding the selection of less expensive products, etc. Which sounds a lot like what they've been doing recently.I guess Canon is still selling more cameras and glass than the competition. Maybe if sales begin to slide, Canon will decide to step up to the plate. I was hoping for a 200-500 f4 L lens. Canon is too slow to react. If it weren't for the great customer support, I'd have jumped ship.
Nikon's 600mm f/6,3 (!!!) is 5200 EUR.I wouldn't pay more then 3k€ for this f5,6!! really guys!
I m hardly thinking about to switch to Nikon to have and use Canon EF, Sony E and Nikon Z!!! all in one system!!! this is the way! Not this shitty high priced or missing lenses what Canon is doing!
Canon is doomed in the tele area! There are soooo many great and "cheap" lenses - but not in the Canon section! You have to pay 500-3k€ or >12k€
Canon is always Doomed no matter what. Before full frame mirrorless they were doomed. then it was no rf mount apsc. Then it was no third party autofocus. now it's ohh the new super tele zoom is going to be too expensive and it's just a rumor. Doomed...Nikon's 600mm f/6,3 (!!!) is 5200 EUR.
Really?
Nikon’s PF supertele Z lenses have been out for 7 years now. You can see the effect of that by the huge increase of Nikon’s market share…but you have to really squint and probably some psychedelics would help.Canon is doomed in the tele area!

Not singling you out in particular but a few people have said why bother when you can put a TC on the 100-300, but as I mentioned above, you can add one to this lens and go longer. From a bird photography perspectives, 600 isn't all that long. And you can't stack RF TCs, so for me the 100-300 would be of little use (though I still covet it).I really don't see the point in Canon releasing a 300-600 mm f5.6 lens especially since that with the RF 100-300 mm f2.8 x 2x TC I get a greater focal range at the same f-stop. Yes, I would expect the 300-600 mm f5.6 to be sharper, but I have shot a lot with the RF 100-300 mm f2.8 + 2x TC and the results are very good.
IMO Canon should have made a RF 300-700 mm f4-f6.3 lens. That I would have purchased. The RF 300-600 mm f5.6 I just don't see buying unless they make it significantly lighter than the RF 100-300 f2.8+ 2x TC. Missing the 200-500 mm f4 is a bit of a disappointment.
Agree that with the RF 100-300 f2.8 the maximum focal length is 200-600 mm f5.6. My concern with the 300-600 mm f5.6 is that adding a 1.4x TC gives you a 420-840 mm f8 lens. Sony just released a 400-800 f6.3-f8 lens for 3K USD and I think Canon is going to struggle to hit this price point against their competition. Lastly, at least for me f8 is awfully dark.Not singling you out in particular but a few people have said why bother when you can put a TC on the 100-300, but as I mentioned above, you can add one to this lens and go longer.

That certainly occurred to me (as one who said why bother because of the 100-300 + 2x), but for birds I’m using the 600/4 + 1.4x anyway.Not singling you out in particular but a few people have said why bother when you can put a TC on the 100-300, but as I mentioned above, you can add one to this lens and go longer.

The 600+1.4 is gold standard of course, although I don't think I would want to carry something that bulky any more.That certainly occurred to me (as one who said why bother because of the 100-300 + 2x), but for birds I’m using the 600/4 + 1.4x anyway.
Fair enough; I'm used to the 800 f/11 and RF 100-400 (plus extenders!) so f/8 doesn't seem dark at all any more!Lastly, at least for me f8 is awfully dark.
