The final segment of 2001 includes distorted images like below to convey an eerie sense. How was it achieved? Did Kubrick use a different lens for these shots? Can anyone specify the lenses he used throughout the film? enter image description here

    Yes, he did use a different lens for these shot.

    It's generically known as a 'fish-eye' lens, with a focal length of perhaps 12mm or less [hard to judge as he was shooting 70mm not the standard measurement which is 35mm]. I'm trying to find more detail, as Kubrick & his lens collection is in itself a massive topic - he didn't rent lenses, he bought them outright… or had them made especially for him - one actually by NASA !

  • Whilst I'm still researching, read this Filming 2001: A Space Odyssey, originally written in 1968. [It doesn't spec the lenses, but it's a really good insight.]

This has so far proven to be a long and not entirely fruitful search.

The generic answer to "what lens is it?" is .. it's a wide-angle lens, very wide - a type known as a fish-eye.
Precisely which one may have to remain speculation. There appears to be a discrepancy in recollection even amongst people who were there at the time.

As to the far broader question of which lenses he used throughout the film, that's a bit harder, but I've found what may be a few specifics.

For the shortest explanation possible in what is a vastly complex subject…
Lenses are termed 'short' and 'long', based on their focal length, measured in millimetres. The term 'short' also equates to 'wide' because of the breadth of view they have, but oddly, 'long' is never called 'narrow', it's called 'telephoto'.
'Standard' human vision is considered to be approximated by a lens of 35mm, so anything shorter is 'wide' and anything longer is 'telephoto'.
To confuse us a bit further, 35mm is 'normal' when shooting on 35mm film but as Kubrick was shooting on 65mm film for a 70mm cinema print, then [because science - you really need to look this up if you have greater interest, it could take a book, or several, to cover this properly] you would need a longer lens to look 'normal'.
A very short lens, 18mm or shorter, will start to be able to see such a wide field of view that it feels like the edges distort unrealistically. A regular phone camera will equate to about 18mm, very roughly, which is why you look a bit squished out to the edge if you're caught towards the outside of the frame in a group shot.
A phone camera is not a fish-eye, though, it's what's known as a rectilinear lens [time to visit google again ;)

Right - whistle-stop tour of focal length over… on with the investigation...

A quick search always puts a custom-built 160° f/2 Fairchild Curtis at the top of the list for that particular shot, but it's not absolutely certain. It's also touted as being used for HAL's PoV [Point of View] shots, but that's also not certain [You will see a pattern to this uncertainty developing, it really seems like no-one actually knows for sure]. The extreme wide-angle lens used for some of the PoV shots of what Hal sees may have been done with a small Nikon fish-eye, specifics unknown, not the Fairchild.
The Fairchild would have been able to fill the frame, this looks like a much smaller lens, though still, of course, a fish-eye.
This is far too different from our bedroom scene shot, plus it's either two different lenses, or it was a very short zoom used at two different lengths [the second shot being even wider than the first], and the lens vignettes to black at the edges.


Kubrick was famous as a lens-collector. Most film-makers rent lenses and send them back afterwards. Kubrick bought them, and chose very carefully. He would have batches of ten sent out of which he'd pick his favourite. He would keep lenses and have them modified to fit different cameras, so he could be using a modified stills lens on a movie camera. He even had some of his favourite prime lenses [a prime is, in effect "not a zoom", it has only one focal length] adapted by Zeiss to new, previously unavailable focal lengths.

In an interview with Christopher Nolan on the recent fully re-conditioned analogue transfer 70mm version of 2001, I spotted this still, with Kubrick and his camera, right on the very set we're discussing. Unfortunately it's not the sharpest image and it's difficult to discern more than the basic shape of the attached lens - which is a kind of 'short triangle' section. So that's about all we've got for identification…

Kubrick on set dream-seq

until I found this rather dry old bit of footage from the bastion of cinema, Joe Dunton, Bafta-winning vice president of Panavision and one-time friend and colleague of Kubrick.

From that, I extracted a potential candidate, the Cooke Speed-Panchro, available in 18mm and 25mm variants, which Dunton claims is "Kubrick's favourite lens"

enter image description here

However, I found two more stills of Kubrick on set with camera.
This with a much larger lens

enter image description here

Possibly more like the Angenieux 25-250mm

enter image description here

Which, having looked back at some footage, could feel about right for part of the 'exercise run round the space station' scene in the centrifuge. It's a wide shot, but not line-bendingly wide like our original question shot.

enter image description here

Then, just as I thought I was happy at that, I discovered this reasonably sharp pic of Kubrick… and a lens I can find no mention of - nor can I quite read the text on it,

Kubrick and pana lens

all I can identify is the Panavision logo, which only tells me it's not any of the lenses we've so far discovered.

I discovered this snippet in the LA Times about the Fairchild-Curtis. Quote from Doug Trumbull , one of the effects supervisors on 2001

In a detailed e-mail on the subject, Trumbull said, “Any claim ... that the Fairchild-Curtis lens was used for the HAL [point-of-view] shots is just not true.” He contended that the Fairchild-Curtis image would fill the entire frame of Kubrick’s 70-mm movie, whereas the point-of-view shots of HAL are round and have vignetted dark spaces to the left and right of the 70-mm frame. Therefore the point-of-view lens would have to have been smaller.

However, from the same article…

Frewin, Kubrick’s assistant, recalls that the director used a 160-degree “mapping lens” borrowed from Fairchild-Curtis for HAL’s point-of-view shots and later returned to the optical company. Frewin said Kubrick also used a “normal, commercially available Nikon fish-eye lens” for other HAL shots.

So… if you managed to get this far - it might be the Fairchild, it might not. It might be the Cooke, or it might not.
Rather a long, tortuous and ultimately unsatisfactory conclusion, I'm afraid.

In one last deperate attempt to gain more information, I ran the original shot through photoshop's lens correction. The basic trick is to straighten all the bent lines then see what focal length that would equate to. The downside is Photoshop, like almost all still-image processors, is based on a 35mm frame size.
Anyway, to just about straighten the lines, Ps reckons the lens would have been a 7.5mm. It's no more conclusive than anything else I've done so far today ;-)

enter image description here

Further research - I found a still of the Fairchild in the pod bay… from How Kubrick Made 2001: A Space Odyssey - Part 4: Jupiter Mission [A]

enter image description here

In part 5 of that documentary, we get a shot of the lens used to be HAL's eye - & may be the Nikon referenced earlier

enter image description here


In the movie 2001: A Space Odyssey they used a Fairchild-Curtis custom fisheye lens, as seen on these pictures. Using a fisheye lens creates this specific distorted kind of image.

Panavision setup


In reference to the HAL POV shots, I may be of some help. Decades ago I acquired a 35mm format Fairchild Curtis fisheye from the estate of Cecil Love, who was tangentially involved (early partners) with Linwood Dunn. Before Linwood died, someone asked what happened to the HAL POV lens and he reported he had passed it on to a friend. You can google that.

I corresponded numerous times with Doug Trumbull before he passed, and he said the lens I have would create the right kind of vignetting for those select shots, mounted on a 65mm body. I showed him photos of the lens and images with various sensors behind the lens for comparative study. Curiously, the lens has a serial number of 0001. It is certainly not as massive as the lens they used for other shots in the centrifuge... but for those frames with just the center sphere, Doug agreed it is a compelling argument and provenance.

Below is a transcript of the message from Doug:

Hi Frank,

Thanks for your efforts to determine the use of the Fairchild-Curtis lens on the 2001 vignetted shots of Keir Dullea. I know of the relationship between Cecil Love and Linwood Dunn and Film Effects of Hollywood. Not too long ago I saw a short video of Jim Dickson talking about (and showing) the much larger lens used for the full frame fisheye shots that were extensive in 2001 (around 300, I think). Jim seemed confused about this big lens being "HAL'S EYE", which is incorrect. (A Nikkor 8mm I believe). I would like to know where one of these lenses is and use it briefly as prop in a documentary film I am developing. My understanding is that these big lenses emerged from Todd-AO long ago, and I can imagine that they fell into the hands of Linwood and Cecil, who were both good friends of Jim Dickson. We used these lenses extensively on the shooting of TO THE MOON AND BEYOND, for the New York World's fair, which predated 2001.

Best regards,

    Hi, welcome to Movies & TV. While very interesting, the question wasn't actually about the lens(es) used for the HAL PoV shots, it was specifically about the lens used to shoot the scene where the pod appears in the room.

    @DavidW OP asked "Can anyone specify the lenses he used throughout the film?", so I think this answer partly covers that. Aug 22, 2023 at 6:53
  • @galacticninja - I agree, I interpret the question as being about lenses used for effect such as this shot. The OP uses the term "for these shots", which seems to refer to the bedroom scenes, but could also be interpreted as opening up the question to other similar shots in the movie. Further evidence of this as you pointed out is asking about lenses used "throughout the film". I assume this was not meant to imply that they were looking for a rundown of every lens used in the entire 2 hr 19 min run time, but rather lenses used for shots of this type. Aug 22, 2023 at 12:41
