My hope is that this lens will perform f/8-11 technically on pair or very close to GM, as I would use it exclusively for landscapes. But if the 1.000 USD price point proves correct, I'm not holding my breath. I wish I am wrong, very wrong.

It’s not so much the AF but the need to advance the ISO due to less light. Also the BG is more in focus compared to the faster teles.
I would be interested to see a comparison of a RX10 MKIV @ 600mm and F4.0 verses the 100-400 with a 1.4X TC yielding 560mm at F11. The RX10 has a much smaller sensor but a 3 stop advantage over the 100-400 with a 1.4X TC.

Yes, if it's that good at f8 - f11 it will be a winner with the landscape crowd.

I don’t think you need the TC to get rx10 equivalent photos if you have an R model. With A7rII/III you can get 600mm-equivalent in crop mode, which gives you 18mp with f/6.3 (rx10 is 20mp). With the RIV you get the same in 26mp.
Your comparison would make sense with A7III/A9.

You won't realize a three stop advantage in the shutter speeds, because equivalency only works for angle of view (assuming you have the same aspect ratio). The RX10 is not a 600/4 lens, it's a 220/4 lens with a 1" sensor, which will behave much more like a 600/8-ish.

Actually, I was concerned with the ISO comparison since the FF camera has lower noise than the 1” sensor. In my experience a very low shutter speed is possible, even for human subjects, with the RX10. Maybe your figures are one reason why?

The 100-400 with a 1.4x would be at f/9, not f/11.

Sony TC should work right?

Does a FLD element make it worse for infinity shooting?

I hope it will be considerably cheaper than 100-400GM and not that far off optically (and closer to 1kg would be a plus as well ). I also hope this will be the last lens to complete my lineup .
I read on another site it is supposed to be "C" indeed...
The 100-400GM is a pretty high bar to compare against. The saving grace of the 100-400GM is that it's already incredibly sharp right from wide open (except maybe @300mm where it takes a drop), so shooting at f/5.6 @ 400mm is not an issue AND it has one of the best OIS/IBIS combinations I've experienced which further makes up for the f/5.6 aperture on the long end.
I keep seeing people say it's OK for a lens to need to be stopped down to f/8 or f/11 to get sharpness for landscapes shots and I say not really. If you are using a 400mm lens for landscapes DOF is not an issue and usually it's all about light - getting enough of it because most of the time there is not enough to keep the shutter speed up (even on a tripod) and the ISO down.
This new lens needs to be incredibly sharp right from wide open as the f/6.3 on the long end is going to make it even tougher to use in many landscape type situations. Also it needs to work really well with IBIS of the Sony cameras and have great OIS too for any hand-held shots.
We'll see soon enough if they have a winner or it's just OK.

Both the current Sigma 100-400 and 150-600 are pretty good already wide open (probably one of the main reasons they are F6.3 at the long end instead of F5.6), although none of the two can touch the GM100-400, which is in another league IHMO (my GM cropped from 400 to 600 was actually sharper than the Sigma @600mm, in fact I've sold it afterwards, even because it was adapted of course)
So curious to see if Sigma found some more mojo to imbue in this mirrorless version

If it comes close to the Sony 100-400 then it is a winner given the Sony is 2.5x the price of the Sigma.
