Patent: Canon EF 200-600mm f/4.5-5.6 IS

FWIW, Sigma has its 120-300/2.8 OS. With a 2x TC it'd be a 240-600/5.6
https://photographylife.com/reviews/sigma-120-300mm-f2-8-dg-os-hsm
This lens retails for about 3600 USD.
So I figure a Canon 200-500/5.6 would cost roughly 4-4.5k.
Now, I wonder, would such a lens be neither fish nor fowl?
Too expensive for amateurs and casual users, and maybe the pros and rich doctors would gravitate to the long primes.

I wouldn't. I wouldn't trade my Sigma 150-600C for a 600/4II straight up if I had to keep it and use it. A prime just won't do the job.

Most willing to spend that kind of money would just go for a used 500mm f4.

Not sure if something changed with the original story over at PR, following the link in the OP.

That article clearly states this is an L lens (in the title of the article). This was dropped with the title here on CR.

Also of note, this is a non-IS lens. IS is not listed in the title nor is there an IS element noted in the patent. IS was added with the title of this post.

I didn't read all 14 pages of this so maybe this has already been discussed.

P.S. I've read a couple speculations of DO elements but there are no DO elements specified in the patent. Lookup the patent for the 400 DO II.

Wow - sign me up for that stubby 'little' 600/4 DO BR!!!

You would not be able to handle that beast without weights training!!

A better option for Canon would be a 300/2 DO with optically matched 1.4x and 2x converters!

Surely the 600DO would weigh less than the regular 600, and plenty of people hand hold/carry that. No weight training required!

Me thinks "handling" is a very subjective term! ;)

Sure, but Neuro and I are talking about the same thing, I think - namely, carrying round and using, with or without support. I have the 500, but use it with the 2x extender, so the weight difference is negligible (less than a pound). I am tremendously weak and unfit, but I manage. So I think we disagree with anyone claiming 'handling' (meaning hefting, carrying, or shooting with handheld) would be harder with a 600DO.

Exactly. Handling. Like this:

That's basically me! Except I'm younger. Ahem :)

That's pretty impressive handling by the looks of it - what if the wind blows?

That was a blustery day at Sachuest Point National Wildlife Refuge in Rhode Island – temps in the low 20's °F, winds were >20 mph sustained with gusts over 40 mph. At times I could hear the lens hood sounding like a pipe organ. Here's a shot from the day:

Not great, but then neither were the conditions. This was shot handheld with the 600 II + 1.4xIII, taken during a hike of ~3 miles, followed by scrambling down ~40' of wet rocks to get to sea level.

OK, far too challenging for me but as they say "where there's a will there's a way". Certainly good exercise!!

Wait, that was you??

And the lens hood does seem rather a wind sock sometimes.

Yep. The photographer, not the ducks. :)

*Waves*

But who photographs the photographer? ;)

A photographer friend of the photographer's. :)
So a photographer photographed a photographer who was out doing some photography and then posted the photograph of the photographer on a photography forum….jeez, this is confusing! ;D
I could imagine how it would get tiring on a long day out, it IS a monster of a lens!

My Sigma 120-300 OS (non-Sport) cost me "only" $2600 AU and the new Sport version retails for much more than that. Lucky I have the same optical formula albeit none of the other enhancements. The problem with this sort of comparison is I still find it hard to believe Canon these days will have a 100m+ diameter lens (even say 105mm and round-up numbers like Sigma) and NOT charge big-white price for it.
