Doesn’t that diagram at 1:04 show the relation between needed IR light and aperture?
Doesn’t that look like a proof of my idea described in comments to MATBOCK Tarsier Eclipse video here: https://ssdaily.tempurl.host/2013/09/05/matbock-tarsier-eclipse/

    You think, not?
    The same situation – smaller aperture.
    And the diagram says “more IR light needed”. (Just because smaller hole lets less light in.)
    Looks like a tradeoff? For me – yes.
    Is it significant? The answer is individual.
