The only regrettable part at large is that a lens can get bad reviews, unless, of course, the push-pull-user admits to his deviant behavior. Anyones guess on that?

I used this push/pull method on my 100-400II occasionally for many years with no ill effects at all.
However, I agree that if someone is yanking or slamming nearly the full stroke of the zoom back and forth continuously for hours each time they use the lens it would likely cause some type of failure eventually. However, in real world practical use, neither of those scenarios would apply. I would imagine not even shooting sports such as football would require it more than a handful of times per game.

Have you ever had any experience with Canon's 100-400 V1 It was a push pull design zoom.
For me, it was my favorite way to zoom, second behind that is the Sony 200-600 with its short throw, half turn to get to 600 from 200.
Any of the other longer zooms out there is not balanced well in hand, when you try to use them as a push pull.

No, I never got the V1. The 400/5.6L was my main lens for several years before I got the v2.
I would prefer a shorter throw for sure. It is the one thing I would change in the 100-500 design too, obviously together with the converter limitations as a very close Nr2. (small pun there, I imagine )
Ok, so I had the 200 to 800 out, and tested the zoom ring. At 200, the 200 mark on the lens is top dead center, aligned with the lens function button. When zoomed to 800, the 200 mark ands up down by the IS on//off button. This is just more than a quarter turn. Maybe about 100 to110degrees or so (quarter turn is 90degrees).
Ef 100-400vII is just over 90degrees. A little less.
Agree. Just got home and unpacked the 200-800. The throw is longer than on the 100-500 for sure but not uncomfortably so, something I would have expected.
But is this a zoom that you'll be actively changing the reach a lot? I think most will park it at 800mm and only pull back every now and then.
I did like the push/pull zoom of the original 100-400mm EF lens but my first made a suction sound as if it was pulling every spec of dust in the area into the lens.
I'll be glad to put up with the extra twist if B&H would send me a shipping notification...

Regardless of how much you zoom or don't zoom, you aren't turning the ring much more than any other 4x zoom. So seems to me the "4 turns to zoom" statements in the YT videos are just an example of people having to find something to say.

I saw one lady with the 600DO this past week. First time. I've seen a number of locals with the 800DO...usually 800DO over one shoulder and 100-500 over the other.
I think Nikon is putting Canon and Sony to shame these days for wildlife lenses.
The pendulum continues to swing. It's Nikon's turn now, but it will swing to someone else shortly.

B&H. I was slacking, took me 15 minutes from announcement to pressing the Buy button.
I ordered mine at Adorama early on November 2, 2023, but it seems they aren't delivering. At least I heard anyone saying I received the lens from Adorama.
And yet another backorder notice from B&H.
Not sure why I'm anxious. It's not like I've got a trip planned until the end of February where this lens will come in handy.
If I were impatiently waiting for this lens, I think I'd be placing orders with several retailers. Especially the little guys that always seem to get a few in once in a while. Whoever ships the lens first wins. All the others get canceled. It's not like you get charged before your order ships.

I ordered mine from Adorama a few minutes past midnight on the release date. I got mine shipped about a week after the first release batch.
So one delivered from Adorama at least. Unfortunately for us, this waiting is not uncommon for launches since COVID.

If you want to take this strategy, please sitck to the big online retailers. Small shops can really get sunk by these things. They may order many more than people actually end up buying, and then are stuck with the inventory. On a larger scale, those orders filter up to Canon, who then may allocate production time differently, slowing other products, and puts out notices about not being able to produce enough for demand, then allocate to key accounts, leaving mom and pop waiting still longer, only to find no buyer in the end. Its a false economy for everyone.
Canon and B&H can afford a bunch of cancelled pre-orders. Many shops cannot.

I think you are over thinking this. If anything, the smaller shops will be fat and happy because word would get out that they have stock and they'd be making good sales. Supporting the smaller shops is important. It's not like ANY retailers (including the big boys) are getting hundreds of these or any other newly released products in and setting on shelves. Remember the R5 craziness? As soon as a retailer got a couple in stock, word got out quickly and they were snatched up in hours. This lens will be no different.
At least on the Nikon side, when a hot new product is just out the door, small shops in good standing with Nikon are the best and easiest way to get the product in the first six months or so. The large stores simply have so many orders that getting one from them involves a very long wait, on average. This more or less even distribution of first samples is good for keeping the smaller stores alive (no they won't stock more than they get orders for, typically) and the larger stores do fine because of the huge number of customers they have. At a later point in time, when the initial demand has subsided, only the large stores typically can afford to keep stock. So they are the fastest way to get an established product that has been on the market for a while.
I don't know if Canon has a similar distribution policy for first orders, though.

Sadly no. Mom and pop shops without an major online retail component have much slower turn times. Just find a few shops in botique industries like this, astronomy, etc, and you'll find the same story. I was in fact made aware of this 'false economy' struggle by a group of small business owners suffering from just this.
I would like to know how many a place like B&H Gets on release day though. Dozens, hundreds, or thousands? I think in the R5 days someone said they had tens of thouands of pre-orders, and were getting low digit thousands per shipment. Not sure we'll ever know the real numbers of course. The one camera store left in my state got zero.
