Canon readies the RF 200-500 f/4L IS with the discontinuation of the EF 200-400 f/4L IS 1.4x

The RF 100-300mm f2.8 is an exceptionally sharp lens and it’s AF speed and accuracy are also one of Canon’s finest

True. The Sony 16-35/2.8 weighs about the same as the Canon RF 14-35/4 IS. Personally, I'd choose the extra 2mm over the extra stop of light (actually, I already traded the extra stop for lighter weight and IS when going from the 16-35/2.8L II to the 16-35/4L IS).
I wonder how the Sony lens will handle coma and astigmatism? This new lens may be good for astro, assuming Sony's bodies have stopped eating stars.I also wonder if it will require digital correction of barrel distortion.
Me too. F4 + a bright wide-angle prime for special occasions, like night sky or astro.
I feel like Canon missed an opportunity to make the 14-35 a little longer, maybe 14-50 F4. That would have made it the perfect travel lens and even a high-end standard zoom for APS-C.

It takes the TCs very well, too. I can’t see myself using it with the 2x, but 140-420mm f/4 will make a great lens for field sports/events.

I suspect that not making a high end standard zoom for APS-C is an intentional part of Canon’s strategy. They want to push those interested in high end lenses into full frame bodies.

The 90D replaced the 7Dii. They had the sales figures and didn't decide to make a 7Diii even though some vocal 7Dii clamoured for it. The R7 - by nomenclature if nothing else - is the high end APS-C body whether it is replacing the 7Dii or the 90D. As I said... A 'true replacement" is whatever Canon defines it to be
Canon makes some announcements but prefers to "surprise" us. They have an internal roadmap for bodies/lenses for sure.
Maybe a RF300/2.8 will be released in the future but logic would tell us that other "gaps" should be filled first if EF lenses are to be discontinued.

Are you willing to elaborate? I was considering getting the 2x for the 100-300 since it takes the 1.4x so well. I have not used the 2x TC before and would welcome any feedback you have on the combination.

Certainly. Apologies for any confusion, I wasn’t suggesting the performance with the 2x is lacking. My primary use for supertele focal lengths is birds, and for that I have the EF 600/4 II that I usually use with the 1.4x, because 600mm isn’t quite long enough. But if I need 600mm, I’d use the prime and not the 100-300 + 2x.
I did post a comparison here:
RF 100-300mm f/2.8L IS USM
Post your images from Canon's fifth 'great white' RF lens and first big white RF zoom, which is also the first big white lens to be designed for RF from the ground up (the first four were adapter±2xTC 'bolt-ons' of the EF 400/2.8 III and 6004/ III, at least from an optical standpoint). This...

My 2cents. Canon restructure the line up so it's not 1-to-1 equivalent to DSLR-era.
R100 = 1000D. See you when I get new passport photos; (
R50 = M50 & x00D
R10 = xxD mix x60D/x50D
R8 = RP & R in-between, taking components from previous mid-high-end cameras and reasonably dumb it down
R7 = xxD & 7D-series in-between
R6 = 7Dx 5Dx Mix
R5 = 5D 5Ds in-between
R3 = 1Div 1DXx in-between

Thank you so much! I appreciate the input! My birding lens is the Nikon 800mm, so I was considering the 2x to fill in more of the sizeable gap between the 100-300 and the 800.Certainly.

In your context, it almost replaces three lenses. A 70-200 /f2.8, a 300mm f2.8 and a 400mm f4. That's impressively versatile.

AFAIK some time ago they've added the option for uncompressed RAW files, which solves the issues you mention. The downside was (not sure if that's still true) that their RAW files were big, since they did not implement lossless compression, at least initially.I wonder how the Sony lens will handle coma and astigmatism? This new lens may be good for astro, assuming Sony's bodies have stopped eating stars.
Now, the reason why the option for uncompressed RAW files was not there from the beginning is well beyond my old brain to fathom

I am pretty sure that every manufacturer has internal roadmaps that are not published outside. Those roadmaps are usually updated regularly, so getting a hold of one may not be very valuable unless it is the latest current one. I appreciate it when manufacturers release roadmaps publicly, but none of them does that regularly and I have to question whether the public roadmaps are identical to the internal ones (at the time of release) or are tweaked versions used as a marketing tool in the hope to entice new customers / excite existing ones.
The secrecy of internal roadmaps is not a necessity, it is a business decision. Some companies are more forthcoming than others for different reasons.I suspect that the RF lenses were on this road map and were influencing the EF linage long before any of us were even aware of the RF developement. I think the secrecy of this road map was essential back then but less so now. The fact that the EF 70-200 f2.8 mkIII was just a coatings update to the MkII...making way for the innotave RF version (all of these features could easily have been made on the EF mount. The fact that Canon never addresses the EF 50mm f1.2 L replacement...but bought out it's effective answer in the RF mount are just two examples.
The fact that there wasn't a ef 300mm f2.8 mk II or a ef 500mm f4 mkIII shouts volumes too. I suspect that the RF 100-300 f2.8 and RF 200-500 f4 were on this map an long time ago and shaped the direction of big white lens developement.
While I agree that the 200-500mm f4 will probably be heavier and bulkier than the ef 500mm f4 II, it will be an exceptional optic. Canon do not drop the ball often and lenses like the EF 50mm f1.2 L are rare. I suspect the weight of the RF 100-300 F2.8 and 200-500 f4 will be addressed in about 5 years time with the mkII version
But, in general, the more the market leader a company is, the less forthcoming they tend to be. I do not have any data to say whether being secretive with roadmaps is a good or a bad thing from the manufacturer's perspective. I do understand it is frustrating for customers. I know I would be happier knowing that the mythical RF 35mm f/1.2L is on the roadmap!
I agree with you that Canon had started investing in RF and divesting from EF long before they announced the "birth" of RF. And exotics have particularly long development times due to the time it takes to prepare and test the larger elements.
