In this patent application (2024-152941) Canon is researching some super telephoto zooms that are most likely some L's. All these designs have internal zoom mechanisms and seem very well balanced, with most of the optical elements near the center or rear.

I think if the long end is a 400mm f/4, then I suspect it will not be cheap. All superteles from Canikony that have >= 100mm front filters are pricey and are L, GM, or S lenses.

The 200-800 front element is not quite that large, but is still reasonable cost wise. It may be a pipe dream, as I've always lusted after the EF 200-400, but if they could land it in the 3-5k range they might have a winner. Even at half the price of a 200-500w/tc, there may be a market, though that would still make it (i'm guessing) $6-8k

Yeah the split happens at exactly 100mm.

Below that you have reasonably priced options like the RF 200-800/6.3-9, Sigma 500/5.6, Nikon 600/6.3, Sony 200-600/6.3 all with 95mm front filter sizes. Beyond that the options become expensive at $5k and up (RF 100-300, Sony 300GM, Nikon 800/6.3).

I also suspect instead of making a dedicated 200-400/4, Canon would rather you just buy a 100-300 and a 1.4x TC for a 140-420 f/4.

I measured the diameter of the front lens of the EF 400mm f/4 DOii some years ago. I can't remember the precise number but it was actually slightly under 100mm. (The true f-number of the lens is ~ 4.2 I recall, and the focal length a bit less than 400mm.)

That might still count as 100mm since theoretically it is 100mm even if the lens design is not quite 400/4 on the dot :p In any case, a zoom will likely need a somewhat larger diameter front element than a prime.

If I win the lottery, or figure out I had a long lost uncle who leave me big money, I'd have a 100-300 with TC for sure. That lens looks great. Truth is I'm getting to the end of my soccer shooting, as my daughter is in high school now, and only has a max of 3 seasons to play, and those mostly being half seasons since she is a club player and there are highschool sports association rules that basically prevent them from playing during the highschool sports season. So the time to get my money's worth out of a lens like that was a few years ago, but I didn't have the cash.

The 100-400vII i bought instead has been awesome though. And its small enough that I'll bring it on a hiking trip. The 100-300 is a bit beefier...

I am guessing that Canon's current production equipment caps out at ~100mm for front elements and that anything larger needs to go through their manual process hence the big cost increase.

An internally-zooming 300-800mm F8 would be very interesting in the "Z" series – as a more portable and affordable alternative to the CINE-SERVO 50-1000mm T5.0-8.9.

Tbh I've been a bit jealous of (the idea of) Sony's 200-600mm F5.6-6.3 given its internal zoom mechanism (which is much preferred for video).

If Canon could put out a Full Frame 300-800 zoom with internal zoom and a servo option, I'd absolutely snap one up for ~$3k or less. (Although I'd prefer a range of 200-600 if I could choose, so as to pick up where the 70-200 leaves off.)
