Nikon has a new patent for a 75x zoom lens designed for 1″ sensor

Nikon has a new patent for a 7.4-600mm f/2.8-6.3 lens designed for cameras with 1" sensor (20-1620mm f/2.8-6.3 equivalent) - this is a 81x zoom to be exact (described as 75x zoom in the patent). Maybe this will be for a new super-zoom DL camera similar to the Coolpix P900, but with 1" sensor. Here are the details:

  • Patent: 2016-156901
  • Published on September 1st, 2016
  • Filed on February 24th, 2015
  • Zoom ratio: 75.5x
  • f: 7.70 - 67.58 - 581.59 (focal length)
  • Fno: 2.75 - 5.02 - 6.44 (aperture)
  • 2ω 92.58 13.446 1.5466 (angle of view)
  • BF: 1.00 - 1.00 - 1.00 (backfocus)
  • TL: 210.44 - 273.47 - 321.86 (total lens length)
  • Inner focus (between the 4th and 5th group)
  • Vibration Reduction (3rd group)

In the past 2 years Nikon has filed several patents for lenses designed for 1" sensor.

    Nikon 1 may yet live

      Nah, strikes me more like a P900-type DL camera in the making.

      I have to say that I don’t understand how those smaller elements are going to grab the all the light coming in from those larger elements.

      • Bob Thane

        That confuses me too. My best guess is that the m8-m15 group moves back and forth in the lens, depending on focal length and aperture. At 7.7mm it can be close like that and still capture enough light, and at 582mm it could move back to capture more of the rays coming through the large elements.

        • Eric Calabros

          m7 and m8 are both flat, but size difference is huge. It would be interesting someone draw ray lines on this.

        • Spy Black

          Yeah, that may be it.

            That’s brilliant, thanks man. I figured it would work that way, but this makes it very clear.

        At the wide end, it is a retrofocal style lens. Front element is a negative power lens that gathers the wide angle light into a narrower light cone and focused down by a positive power lens. Because of that, the positive power lenses can afford to be small. At the long end, they shift about the lens groups to make it a telephoto. https://en.wikipedia.org/wiki/Ang%C3%A9nieux_retrofocus

    This camera like their initial DL series cameras might be vaporware that Nikon execs have been smoking and hallucinating Nikon dominating the camera market.

    • knappeduivel

      It is a lens, not camera.

  • MSC

    A little help requested with reading the blueprints. Am I right to see 30 elements (!) in this lens?

    • Shutterbug

      It’s not unusual to have that many elements.

    • DaveR43

      I think the ‘m’ numbers are the lens surfaces, not the elements. I see 15 elements, maybe one more:

      L1 – 4 elements
      L2 – 4 elements
      L3 – 4 elements
      L4 – 1 element
      L5 – 2 elements

      I’m not sure of the implication of FL.

  • MonkeySpanner

    If you need to go 24 – 1500, I guess this is your lens (if it is ever made).

  • Espen4u

    Lot’s of glass for a small’ish sensor camera. Don’t get me wrong theese type of lenses will sell (fun factor), but they’re not for me.

  • Aldo

    Nikon seems to be the answer to debunking lunar conspiracy theories… soon we’ll be able to see the landing sites from earth.

  • BG

    Surely, it will be tack sharp center to corner at all focal lengths… :-/

    • PhilK

      It is possible to make outstanding quality, very high zoom-ratio lenses. Take a look at what the lenses used at major sporting events for television broadcast are capable of.

      They just happen to be very large and extremely expensive. 😉

  • 75 is 580 / 7.7 so I guess the quoted range is for marketing purposes or they don’t consider performance at the extremes to be good enough and plan to restrict the zoom mechanism.

  • JL

    If you compare it to the lens layout of a common 150-600 full frame lens, this lens has almost the same size, maybe it’s a bit shorter. So this will not be the average travelers’ lens, you must be a dedicated 1500mm shooter to buy this huge “compact camera” or 1-Nikkor lens.

  • The P900 is pretty awesome, but the sensor size and the lack of NEF capture is definitely limiting it to B-roll type work. To have a ~1600mm lens in a compact body with a 1″ type sensor, (assuming that it’s actually decently sharp, and offers NEF, thus making it more than just another stereotypical superzoom) …that’d be something I would want!

  • Dino Brusco

    I really wonder why instead of such nonsense they make a 18-180 fast and corrected enough, for 99% of everyday task.

    • PhilK

      If Nikon doesn’t build it for that class of camera first, some competitor will.

      Personally I’d rather see Nikon be the one making these sorts of pioneering products first. Absolute optical quality is less important for that class of cameras than flexibility and marketing buzz is. The P900 provided a huge PR/marketing boost for the company. They could absolutely use more of such things. 😉

  • Szu-Ping Lee

    Being a wide-angle guy, I have always wondered why most fixed lens cameras’ wide end stops at 24 mm (eq.) and not wider. It will be killer if Nikon can make a decent 20-120mm zoom for 1″ sensor. Nothing in the market at the moment can touch that.

    • PhilK

      Generally speaking, because there are more and more optical compromises that must be made to build zooms into superwide territory, unless you want the lens to cost $3000, be the size of a battleship, have lots of distortion, be unsharp, have a tiny maximum aperture, and so on.

      • Szu-Ping Lee

        PhilK,
        I know that wider angle is more difficult to design and maintain quality. But I don’t think extending out slightly to 20 mm will be all that hard, especially for a 1″ sensor and with distortion correction. The old way of thinking is that 24 mm is wide enough, but nowadays many people demand wider. That is the reason why Nikon has a 18-50 in its DL line. I currently use a Sony RX100 IV and wish its wide end is at 20 rather than 24 mm, even though it is a fast lens. I look forward to some day they will give us a good quality point-and-shoot with 20-120 zoom.

        • PhilK

          There are many things that are technically possible, but are not practical for either practical or marketing reasons. (Camera too big/heavy, f/stop too slow, price too high, etc.)

          Any company that makes a consumer product has to consider these things very carefully. You cannot build a product that is either so expensive that few will buy it, or so technically impractical that no one will be willing to put up with its compromises.

  • JoeFunny30

    I’ll buy that
