Or a very very high zoom to get a similar effect.
No real reason for this question, just a random wonder I had. Basically the effect this would have on perspective might be interesting, and I wonder if any movie used this kind of shot for more than a couple of seconds.
- Not a telescope, but Barry Lyndon was shot using lenses designed specifically for the Apollo program to capture the dark side of the moon. - The large aperture of these lenses allowed Kubrick to shoot scenes lit only by candlelight, and helped make every frame look like a painting. - That’s quite impressive. Is this it? https://www.youtube.com/watch?v=YQE73GDo4So - Yes, that’s a good example, though there are several other candlelit scenes in the film. - It might not be Kubrick’s most exciting film when it comes to plot, but it’s certainly remarkable and unique when it comes to its cinematography. - Definitely a must see (at least once) if you’re interested in cinema as a visual art. 
 
 
- Little gimmicky how much it’s used but the movie “Phone Booth” has tons of these shots. It’s like half the movie. 
- Poor Things has a bit of this, as well as a ton of other very interesting lenses. 
- I don’t have specific movie examples, but the narrow depth of field of a zoom lens would certainly require careful cinematographic considerations. It would be hard to compose a shot that has a typical foreground and background, without accepting that the background might be massively blurred. But I can sort-of see the appeal of having things chronically out-of-focus, as a way of hiding “obvious” details from the audience, until the focus changes and makes the big reveal. - Maybe such a film would be trying to artistically emulate human “tunnel vision”, where depth perception is severely reduced. 
- Not sure if this is exactly what you’re looking for, but the opening scene to The Conversation uses a high-zoom shot: https://www.youtube.com/watch?v=wlwdpNw1FW8 - Eye in the Sky also prominently features long-distance/high magnification shots from the perspective of a drone/UAV. - This is precisely what I meant, thanks! 
 
- Rear Window has a lot shot though a telescope, or at least it’s intended to look like that. Not sure if AH did it for real. 
- Rear Window? - Cosmos? 
 
- I think you’d find the aberrations problematic for the speeds needed for live action. I think you’d need custom optics to get low enough f-stop and likely some very expensive custom achromatic lens stacks to correct most of the visible wavelengths.
