Still, it is kind of odd. Wouldn't a 600mm f/6.3 prime be cheaper to build than a 150-600mm zoom?
But tougher to sell, I think.
Yes, all of us who prioritize quality and reach at an affordable cost will recognize that a prime makes the most sense economically and technically. But we are a small market.
If you shoot for a living and what you shoot needs the reach of >= 500 mm, then the $8-$12 K investment in the industry-standard 500 f/4, 600 f/4 etc. is what you are going to do.
If you are a hobbyist or a weekend-warrior type photographer then you probably cannot justify $1-3K on lenses, and if you can, then that zoom is going to appeal to you a lot more because you don't know or care about any extra quality for the prime.
Add to them the large market out there comprising folks who actually do prefer the convenience and flexibility of a zoom as long as quality is sufficient for, e.g., web and (small) print such as for the few newspapers that still exist or non-full-page image for magazine spreads: sports and other photojournalism.
Also add the folks who use the term "zoom" when they mean "telephoto", and in fact characterize reach in terms of "my Gillette camera has 10x zoom, I want that for my Canon", and have never heard of the term prime, and quite content to take a full-auto shot of Eurasian tree-finch occupying the middle 5% of the frame sitting on the telephone line at the end of the yard under an overexposed sky and over suburban dreck, a.k.a. the marketing folks primary targets, who would be happy to drop $2K for their hobby glass as long as it has lots of features like a zoom and DX-RGG-WOWZA coatings and hyper-ultrasonic-focusing and crystal-good-vibration stabilization.
Compared to all of the above, we are a relatively small, niche group, the impression given by the dominance of our presence in these forums non-withstanding): folks who need the reach, and have the technical know-how to recognize the trade-offs between a zoom and a prime and still prefer the latter, and cannot justify the expense of a high-end 500/600 f/4).
And, so you can see, from a marketing/selling perspective the zoom makes so much more sense of the prime.
Especially since, when it comes down to it, the overwhelming majority of us will end up buying one of these zooms anyway given that nobody is going to make use the 600 f/6.3 we want due to the calculus described above!!!
