Most lenses from 35mm on up on Vista have very little distortion, if any at all.
    That is incorrect. It has been debunked many times. If the object distance is the same the geometric distortion is the same, optical design notwithstanding. Simple geometry

    The point is that there absolutely is a difference between FF and s35 and the idea that it is irrelevant to go FF and that you can get the same look on both sensors is just not true except when the intention is to match them up. Being able to match them does not mean them being equal in all ways.
    The real cinematographers position the aperture where the story calls for- not at the widest possible opening. That's called a creative choice...

    The "real" cinematographers absolutely do that and they usually choose exactly as I mentioned they do. But the "real" cinematographers also choose according to their own artistic preference or the director's preference. I would love to hear you bash Fincher for not setting his apertures "according" to the story since most he has done has been done wide open except edge cases like Mank. But since you call Meizler incompetent, I guess you don't consider him a "real" cinematographer because he shot wide open like he did?

    He is absolutely a very accomplished pro. He made a creative choice that fit the story. Orson Welles and Gregg Toland also made such choice in Citizen Kane. It happened to be deep focus..
    Arguably shooting Helium with a 20mm f1.4 lens would give indistinguishable result....

    Right, optical design not-withstanding. That's the key point. In this scenario, Meizler was comparing shooting on an 18mm Super Speed (which optically has a lot of distortion) to shooting Vista on a Zeiss Supreme 35mm (which has very little distortion).

    Generally speaking, these new FF cine lenses have very little distortion from 35mm up.

    Of course, but he could as well shoot with 18mm MP , very little distortion

    Ah. I see you didn't read my post. In terms of the format jump, 1.6X in this case in the example shown.

    and vice versa- 1.4 is the f-stop.
    also, to be clear- that calculation was just an example of a stop compensation for an FF(44) lens at f1.4 (hence the 1.4x) to equiva-lens for S35 (31). Just to avoid this comedy of errors and waste ;-) typing energy in the future

    Love those tests.

    OK lets compare:

    Here is your 18mm Master Prime on S35:

    And here is the Zeiss 35mm Supreme on Vista (Alexa LF):
    https://www.youtube.com/watch?v=DqfWvGNkoJc

    I'd say these feel pretty different, even if you allow for the slight variance in framing.

    The 18mm feels like a wideangle.

    The 35mm feels like a telephoto.

    Feels pretty different to me. Look how compressed the background. Looks telephoto. Whereas the 18mm Master Prime look wide-angle.
    Of course it looks more telephoto. Apples to oranges. Either compare 25mm on lf to 18mm MP on S35 or compare 35mm on lf to 25mm MP on S35. At the same distance. I thought we had that down....
    with 1 stop compensation of course etc, etc...
