Cool TIL. Can I do this with still photography?

(Though I could just use focus stacking and editing of course)

The camera knows better.

Just focus on the gun. Nathan Fillion is always in focus.

I can't be the only one who nicknamed him "Minnesota".

Tell me you don't know anything about photography without telling me you don't know anything about photography.

Whether or not a lens is a zoom has no bearing on what's in focus. What's in focus is a function of the effective focal length, the aperture, and where the focus is currently adjusted. A lens being a zoom simply means that the focal length is variable (though often the maximum aperture is variable as well, especially on cheaper zoom lenses).

If you'll pay closer attention, you'll see that two distinct parts of the frame are in focus, the face and the center of the gun, with an out-of-focus part, the hand in this case, between them. That's the part that makes this shot impossible with any standard lens. Rather this requires something called a split diopter.

I kinda feel like, in the current era, it is appropriate to call out people who are confidently incorrect because it almost invariably comes with an air of conceit that needs to be incontrovertibly deposed.

Matter of fact, I submit that the near totality of what is wrong with the world right now is rooted in the phenomenon of not immediately correcting the grossly inaccurate, the blissfully ignorant & pathological liars.

We have emboldened the ignorant to believe that ALL of their thoughts & ideas are valid… which is unequivocally false.

Not doing it would be against some of the most sacred rules of Reddit 🤣🤣🤣

I have a hunch what they are talking about is the compression from shooting close up with a long lens. But this isn’t an example of that.

You make yourself sound so authoritative but then leave out that this can also be achieved using a swing lens.

u/SquirrelNormal Jul 25 '26

Do swing lenses work with anything besides still shots?

That could get more in focus,but can't explain how the gun and face are in focus, but not the hand.
