Value is a personal choice. What 'many categories' are you talking about? From your comments, it's apparent that you believe Nikon's 600/6.3 and 800/6.3 lenses offer 'more value'. I would argue that lenses costing ≥$4K are niche products, and that Canon's RF 100-400, 600/11 and 800/11 lenses offer much better value to a much larger number of people.
Value is usually measured technically in BANG for BUCK, so the Nikkor primes, banging much higher than they are bucking, have a good value, as they are seen as alternatives for the big fluorine elements primes. The RF 100-400 is ok value but leaning on the cheap side, the 600 and 800 also pretty good value.
You also mentioned f/1.4 primes. Do two lenses, one wide angle and one standard, comprise a category? Or is the category 'f/1.4 primes'? If you are going to compare them to Canon's f/1.4 primes of the same focal lengths and ignore that the latter are L-series lenses, then you would also say that Canon's RF 45/1.2 is a much better value than any of Nikon's f/1.2 S-series primes? Or would you say that's not a fair comparison?
The two Nikkor primes are excellent value, particularly in comparison to the bottle bottom that is the 45mm F1.2 (which I have and like very much, but value? It's a fun lens but not good value. RF 28mm F2.8 is good value! Canon VCM series, bad value but nice lenses for whom needs the video features and not being able to recognise which lens they're picking up (joking of course). Nikkor 1.2 monsters? Worse value of all.
The VCM lenses are L-series lenses, with L-series optical quality. Calling them a worse value than consumer-level lenses is silly, IMO. Yes, they are more expensive...and they are professional series lenses. I get that you don't like that the RF 35/1.4L (like other wide/ultrawide VCM lenses) requires digital correction of distortion. So let me leave you with an image from a review of the Nikon 35/1.4 without CA correction. Would you be happy with that uncorrected image, or would you say that digital correction is needed? If it helps, you can view the image while listening to
the appropriate music.
You're talking to the wrong person if you think I have anything against digital corrections. But when digital corrections - which should enable to bring sharper and more compact lenses for a lower price - are sold at premium prices, than value is gone (no digital correction will bring back those BUCKS!)
Yesterday I had the chance to test the Z8 + 800mm f6.3 for two hours. It was awesome! I know exactly one like this won’t ever come from Canon - even not for this nice price!
Summed it up pretty well!
For the their respective full frame mirrorless mounts with focal lengths in the telephoto/supertelephoto range:
- Canon – 12 zooms, 12 primes
- Nikon – 10 zooms, 9 primes
- Sony – 12 zooms, 10 primes
How is Canon is lagging way behind? I suspect your answer boils down to something like, "
They're not making the telephoto lenses that I personally want." IMO, it's always good to be in touch with objective reality.
Out of curiosity, does the 75-300 count in the 12 Canon zooms?

That should be a -1. Jokes apart, it's clear that Canon has a big hole in the 4k-6k range for bright telephoto (Sony 300 2.8, Nikkor PF, Sigma 300-600). You are blinding yourself with side arguments imo. And just to end on a friendly note, I love Canon gear and respect much of your opinions, I always learn from your comments here
EDIT: forgot to show appreciation for Hendrix. Here's to digital corrections and being forced to use DPP to get a decent JPG!

(joking... maybe?)
